Bearing Buddy Operation

Replace your existing grease cap with a Bearing Buddy to ensure a safe, easy way to monitor and control the level of grease in your axle hub. To adjust the amount of grease in the hub, use a grease gun to add more through the appropriate fitting. Adding grease moves the Bearing Buddy spring-loaded piston outward 1/8".

The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The interior of the Bearing Buddy is pressurized, preventing water from entering the barrel and diluting the grease.

An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This prevents overfilling that can damage the inner seal.

You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

Video Transcript for Trailer Bearings Races Seals and Caps Rebuild

Speaker 1: Today we're going to take you through the rebuild process on a couple of hubs. We've got an idler hub, and here we've got a hub and drum assembly. Works with electric rigs, but this can also work for just standard discs, if you've got a disc brake style setup.Basically what we're going to show you is how to get all of the bearings out. How to remove the seal. How to remove the race's if they're damaged, then get them replaced in the proper manner. We'll show you how to use an easy loop hub, which we have here.The first thing we are going to need to do is, get the grease cap off the end.

It can have either a rubber plug in it like this one does, or it can be a solid metal cap.These are pressed fit in there, basically by tapping on them on the back side. To remove them, a deadbolt hammer is typically what we're going to use. We're just going to start tapping as we go around. You'll see a little separation start right here, and slowly it'll work it's way off.Now the next step's going to vary a little bit depending on your axle setup. Do you see this is going to have a keeper that goes around the nut.

And that prevents that from being backed off, or removed. A lot of times you'll have a castle nut, which will have just little tabs that stick off, and there will be a cotter pin that passes through it. Just depending on your application, you need to get the keeper for the nut off. This style we just kind of pry out. A cotter pin you would just remove of course.Once we have that off ...

We'll start to take off the nut here, and the washer that's in behind it. Now yours should look a whole lot more dirty than this. There should be a lot of grease packed in, and through the hub, this one's brand new. We thought it'd be nice to show you the components before the grease was on .. Of our washer that comes off.And then here we're going to have our outer bearing.

Continue to pull that. We're gonig to have our inner bearing here. That sits in the backside of the hub. And we didn't put it in yet, we will show you how to put it in. But a seal would typically be covering the backside here. We'll show you how to use a seal removal tool, or another tool. To get that pried up and out. To get an access to that inner bearing.Now for a drum style like this, that process for disassembly is going to be just the same. One thing to keep in mind if you're using a disc brake setup. You'll have to remove the caliper before the disc is going to come off.Now once we have the spindle exposed, as we said this is going to be really greasy. We want to get all the grease removed, and the first thing we'll do is inspect it. We want to make sure that it looks just like what we have here. Everything's nice and smooth. We don't see any kind of discoloration, or any marring on the metal. Indicating that our bearing's got hot.If you do have any of those symptoms, at this point it's time to replace those bearings. You don't want to repack them. Get new bearings, and put in there. You might have a bearing that's come apart in here. Another surface to ensure is in good condition, is where your seal is going to go. That helps seal all the grease inside of our hub. With a damaged or broken seal, that grease is going to seep out. Either out of the hub, or in this case into our brake assembly.Now if your axle has brakes, we're also going to check the disc. Make sure it doesn't have any issues, or your hub. And this is going to be a hub and drum assembly. The brakes are going to ride on this machine surface. You're going to check that for signs of excessive heat, discoloration, or cracking. And this is our magnet surface. We'll check that surface for the same issues.Now inside the hub regardless if it's a disc brake, it's a drum brake like this. Or just a standard idler style hub. You're going to have an outer race. Would be right here, it's a small tapered piece of metal your bearing sits in, and rotates on. That's basically the outer portion of the bearing.You have the same thing here on the backside. This is called the inner race. Now if those show any signs of wear, overheating, or cracking. Those are also something we'll need to replace, which we'll show you how to do in just a minute.Now, with your brake assembly exposed, if you do have electric brakes like we have here. It's a good idea to check all the components for wear, cracking, maybe missing pieces. Check your pad thickness to make sure those are in good shape. Basically if you have a non working brake assembly and you put everything back together, you're just going to have to take it apart and do it all over again to get back to the brake assembly. This gives you a really good option to be able to change them out.And most applications are going to use a four, or maybe a five bolt flange to hold them in place. And you'll just remove the lock nuts, or sometimes you'll have a hex nut with a lock washer. You want to remove those, and then simply slide your assembly off after you cut the wiring.The friction material itself should also be checked for any kinds of cracking, or overheating. If you have any grease inside the system at all, it's likely it's gotten on those pads. It's a good idea to get those changed. Now as far as the removal of the races go, it's going to be just the same whether we're using an idler style hub like we have here. A drum brake like we have here. You can basically see where the idler is, here in the middle of the hub. It's going to go all the way around there, and we just have this extra material here to provide our braking surface.Now if you're doing a disc brake style job again, it's going to be just the same here with the races living inside of the actual hub portion. You'll just have the discs there for the brakes to make contact. We're going to use this little bit smaller one, it's a little bit easier to manage to show you how to get these out. We've talked about where the races are. The outer here, the inner being closer to the inside, but on the backside of the race there's a little lip. That lip's meant to stick out just a little bit further than the hub, and provide us an area to put our tool on, and help to drive that out.If you look all the way through there on that inner race, you'll see that little lip that sticks out just from the hub slightly, and it gives us enough area to use our tool on. Now generally to remove these you're going to use a punch, similar to this. Some guys will use a screwdriver. Or a piece of pipe. If you have a piece of pipe that's small enough to fit inside of that diameter, you can take that down through and allow it to rest on that lip.Use our punch, and then just need a hammer. And we'll start working that out. We're going to tap all the way around. Kind of equally, and evenly apply the force to get it to come on out of the bottom for us.You can see now as it starts to come out there's going to be a little gap created between the hub and the race. And we can just keep going, bringing it on out. Then you can inspect the inside of the hub surface there. Make sure no damage or anything has occurred, and repeat that same process for the outer race if you plan on removing and replacing that one.Now in the outer flat edge, you can see we're going to have our tapered edge on this side. If we roll our race over to the flat side, typically there's going to be a manufacturers part number on there. That will help you identify which race it is, that you need to go back in your system. If those are rubbed off, worn off, if you can't read them. You can measure the outside, to outside diameter of the race here. It's a good idea to use a micrometer to get it exact.Now here's your basic micrometer. And again, the outside of the race is what we're going to need to measure. You want to go . I set the thickest point there. Looks like this one's going to be about 1.98. That's going to be the measurement you'll want to supply.Now while we've got this out, let's also look at the proper way to measure our bearing. Instead of the outside for the bearing, we need to measure the inside diameter. That's going to be pretty simple. Let's pull that out, find the largest measurement we can. Which here, looks like it's going to be 1.03. With that information, we'll be able to get the correct bearing, and the correct race, so they'll fit together properly and make a full bearing kit for us.Now here's the race, we're going to show you how to get this put back in. Basically just going to press fit inside of our hubs. We need to get it down on there. Kind of like that. And you'll have a couple options. A lot of times you're going to see do it yourself or at homer, just going to use a wooden block. Just place it on there. That's going to get you started, but at that point you'll struggle in getting it to go all the way down into it's seat.Now to take care of that problem, there are several seal drivers that are available. Seal and race drivers that are available out there on the market. It's designed to fit down inside of our race, inside of our hub and get it down there where it needs to go. This is part number ptw83020, has several different sizes, even if you have multiple trailers it's going to do the job.Now the side with the angle on it, is designed to fit down inside of our race. If we use the other side, that's going to be for driving your seal into place. Just want to hold it, and take it on in with your hammer. You'll see, you just want to insure that our race is all the way up against that line on the hub where it's supposed to mate to.Now when it comes time to pack your bearings you're going to have several different ways of doing this. You can just use your hand, is the traditional method. That's going to be the method probably reserved for the very occasional trailer work kind of situation. If you do it once or twice a year, probably get away with it that way.Next you would go to a, kind of a sandwich funnel style almost. If you look inside of there, you can see the bearing. It's located between the two pieces. Just use a grease gun. Start filling that with grease, and that's going to fill our bearing for us. And the third, with this one you're just going to place your bearing down and in. It should be pretty close to center. And then we've got our cone her that's going to go down and secure that.Now I think this style, wastes a little bit more grease than what this style will. This has a dust cap. You can see, you can keep your grease in there, put your dust cap on there and save it for later use. This will be if your going to do it every couple years. And this particular style would be if you're a more regular user.Let's start by showing you how to use a bearing packer. Similar to this. Again, we've just got our grease inaudible 00:11:07 here on the top. And then just slowly start to fill it. Now I like this style quite a bit. I think even regular users might enjoy it, because you can get a really quick visual look at that bearing. You're not going to have to overdo it, or have to much grease.You can kind of see in there now, we're starting to get grease to come out of it. Couple more pumps, we'll be good. You can see we've got grease coming out all the way around. Where all of our bearings are. Got a little bit of excess there. Just take that around the outside of it. And then we should be able to lift it off. And now you can see what we we're talking about. Just a little bit of excess there, that you're just going to wind up wasting.Now we'll take our bearing, we're going to place it right down in our race. And then we'll cap off the back with our seal. Right now our seal's going to fit in just like our race did. It's going to have a little bit of a pressure fit to it. Now very often in this situation, I see people using the four by four method. Kind of here, just placing that on and tapping it. As an option though, if you do have one of these. You can see that's designed to fit right on the top of the seal. And help drive it in.The biggest thing here is, just going to be getting it driven in squarely. You can see, this side's in a little bit further than this side. I'm going to start this side first. Now since we didn't have the opportunity to show you before, we're going to take a look at pulling a seal. Now this is a seal puller, we carry this on our website part number ptw1219. This is meant to hook underneath the seal. And then you kind of pull up on it, and just like our race you'll have to work all the way around that edge. Just bringing it out a little at a time.If you don't have that available. Another option would be a screwdriver. You just kind of get that under the seal, and turn it. And see, that'll allow you to also pop that out. We've taken care of our race. Our inner bearing. Our seal. The last component, before we put our hub back in place is going to be our outer bearing. Now with this bearing, I'll show you the hand packing method.This is definitely . Slightly dirtier method than the bearing packer. When we get grease on our hand we want to look at the larger side of the bearing. This is the smaller side. We have a larger side In between the inside and outside there's a gap. We can see our rollers in there. We want to grab that, and use that gap and shove grease inside of it. Now this is going to take a little bit, you want to work in the same spot until you get the grease pushed all the way through. We can see on the top there we've got a little bit starting to come through.And once we push it in the bottom, and you see it start coming out the of the top in those little drips, it's going to indicate that, that section's fully packed. Just need to work all the way around their outside edge now and do the same thing. Alright, once that's all the way around . The bearing will be ready for use.Now one more thing I like to do. We can see our inner bearing there, and our outer bearing. Well between the two, got a pretty big gap in there. If you'll take a . Pretty good amount of grease. We're just going to go all the way around. See how we can go all the way around the inside and just line that really well. The more grease we have in here, the less chance we have of any moisture getting in there, which can cause corrosion, rust, pitting. Pretty much things we do not like when it comes to bearings, races, and hubs.Put plenty of grease in there. And then this one does have the easy lube spindle, that'll even fill it in more. Now we can get our assembly slid on. I like to keep my thumbs on that outer bearing, just to prevent it from . inaudible 00:15:28 pushed off there. Now we can put on the original hardware that we removed, in taking off our hub the first time. In our case, we had our washer and our nut.Now most commonly you'll see pliers similar to this being used. We basically want to get that tightened down. Once it's fully tightened down you'll feel some resistance in the hub. We back it off just slightly. That'll give us a little bit more freedom of motion there. Something you don't want however . Is any movement in, or out on your hub. You want to be sure that everything is compressed, and you don't have what's called end play. Which would be the play in and out.Once we've got that set, then you'll put on whatever tight keeper yours came with. Get that put back in place. Now with an easy lube style hub, you're going to place your grease gun on the end, and then you can just fill the remainder of that hub up.Now for your typical applications, you're either going to have a solid cap, or a cap that'll have a rubber plug in it. A solid cap's going to be for an axle without the grease inaudible 00:16:51 here on the end. Goes on there. Just knock it on with your rubber mallet. Same with the one with the plug. Just gives you a removable area there, be able to cap that off.We'll show you how to put that on. Now as alternatives as well, a lot of times on boat trailers and marine kind of situations. You'll see a bearing buddy. This is going to apply a little bit of pressure on the grease, you'll fill it up. This kind of comes out just a little bit. That applies constant pressure on the grease to make sure we don't have any air, or anything like that. Then there is also an oil bath hub available. Now this is going to be for use with seals that are going to be designed specifically for oil bath use. You'll have to change that seal.We're using a double lip seal. There are also single lip seals available. Of course a double lip seal is going to give you just a little additional security. Keep that in mind when you order. But let's get this knocked on there now so you can see how that works. We just want to take the cap, we're going to center it. This is going to be very similar to what we did with the seal. And then just gently start tapping it around the outside. And it'll seep down on there for you.It's really going to be the same thing that you'll do with any of the end caps. Now with this side done, it's a good idea to take care of all the other hubs. Get them all on the same maintenance schedule. And as long as you'll periodically check the grease, take your trailer out for a trip occasionally. Just to keep everything lubricated. It should extend the life of these parts, and give us years of good service.

Liked these until the 4th and last one I removed to tighten the nut. Wasn't too happy with this one. I thought they would be one piece. Took a large pair of water pump pliers and a crowbar to get the insert out. Needless to say I had to order a replacement. I'd have given it 4 stars until this. 704679

  • Bearing Buddy Bearing Protector for 7,000 Pound Trailer Axle
  • The most common hub bore diameter for 7,000 pound trailer hubs is 2.717", for which the Bearing Buddy Bearing Protectors # BB2717 will work perfectly. With that being said I still highly recommend verifying your existing hub bore diameter with a digital caliper like # 301-17068 to be certain, as not all 7,000 pound hubs are created equal. I have attached a short video review on this set that you can check out as well.

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
  • Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

  • Bearing Buddy Protectors for 7,000-lb Dexter axles
  • Thank you very much for your follow up question. The Bearing Buddy Bearing Protectors # BB2717 are designed to work with outer bearing model 14125A and outer bearing cup (race) model 14276, which are commonly found on 7,000-lb Dexter axles. Most grease caps on 7K axles have a flange diameter of 2.722 because they are made of very thin metal and are designed to slightly crush when they are pressed into the hub bore. The Bearing Buddies don't crush as easily so they are made closer to...

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
  • Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • Bearing Buddy Compatibility with Dexter 6000 lb Axle
  • I'm assuming there is a typo in the ID you gave. Based on the Dexter 6K hubs, it appears you may have a 2.72 grease cap. That is the closest I found to the size you gave. The Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated (Pair) # BB2717 would be the fit for that model. If you can give me the numbers on your hub, I may be able to pin point the correct kit for you if there is one.

  • Selecting Correct Bearing Buddy for 8-Lug Hub on 7000-lb Axle on PJ Dump Trailer
  • Selecting the correct Bearing Buddy bearing protector for your 8-lug hubs requires that you know the hub's bore where the grease cap (or Bearing Buddy) fits. This requires using a precision digital or dial caliper and measurement to the nearest thousandth - 3 decimal points. You also want to note whether you hubs are threaded or non-threaded as we offer both types of Bearing Buddy. For example, we offer an 8-lug hub for 7K axles, part # 8-219-4UC3, and this hub's bore happens to be 2.720-inches...

  • Will Bearing Buddy # BB2717 Work With AL-KO 7,000-Lb Axle
  • You will want to use a digital caliper like part # PTW80157 to measure the inside dimension of your hub to make sure you get the correct Bearing Buddy. The Bearing Buddy Bearing Protectors, part # BB2717 are designed to fit a hub bore that is 2.717 inches diameter. If your outer bearing is a # 14125A, then the # BB2717 would work for you.

  • How to Remove Bearing Buddy Bearing Protector From Hub
  • The best way to remove a Bearing Buddy Bearing Protector like # BB2717 is pretty much what you've been doing. Because the fit inside the hub bore is pretty tight, you just have to take a rubber mallet (or wood block) and firmly tap it around the sides until it's unseated and loosened up enough to pull it out by hand. This process is briefly shown right at the beginning of the video I attached below. If your Bearing Buddy came out in a couple of pieces it was likely damaged in the removal...

  • Can Bearing Buddy Bearing Protectors Be Used on EZ Lube Trailer Spindles
  • You can indeed use Bearing Buddy Bearing Protectors on the EZ Lube spindles for your trailer but as you mentioned you will first need to cut off the zerk fittings. The zerk fitting would prevent a proper fit but once it's removed you're good to go. If you are blowing seals though with the E-Z Lube spindles I would first check to make sure you aren't over filling the hubs with grease. Using a double lip grease seal will also help this. The Bearing Buddy Bearing Protectors # BB2717 that...

  • Bearing Buddy for Trailer Hub that Has Bearing Number of 25580
  • Since you didn't specify which bearing of your hub is 25580 I am fairly certain that the correct Bearing Buddy you would need would be the part # BB2717. But you will need to measure the bore where you old grease cap sits currently to verify that it is 2.71 inches in diameter.

  • Which Bearing Buddies Will Fit a 2-7/16 Inch Hub Bore
  • You will likely need 2441 model Bearing Buddies: # BB2441 for chrome or # BB2441SS for stainless steel. Your hub bore will be slightly less than this if it is exactly 2-7/16 inches and that ensures a tight fit. The hub bore should really be measured using calipers such as # PTW80157 because the measurement has to be as accurate as possible.

  • How Does Inner Bearing Get Grease When using Bearing Buddy
  • Bearing Buddy pumps grease into the center of the hub all the way back to the grease seal. A double lip seal should be used to prevent grease from blowing out the seal when added. When the hub and seals and bearings are first assembled, they should be packed. After a period of time and when you want to maintain the grease on the bearings, the grease would travel from the zerk fitting on the Bearing buddy through the outer bearing. It would then fill the cavity inside the hub and continue...

  • How to Measure for Selection of the Correct Bearing Buddy Bearing Protectors
  • There are two ways to measure to determine the correct size of Bearing Buddy Bearing Protectors you will need. The First way is to measure the outside diameter of the bearing cap installation surface. If the bearing caps are removed gently without deforming them then this is the easiest way to measure. You will need to use a Dial Caliper to take these fairly precise measurements. The other method of measuring also requires the use of a dial caliper. You will need to measure the inside...

  • Recommended Hydraulic Brake Assemblies, Actuator, And Brake Lines For Dual Axle RV
  • For your conversion to hydraulic brakes on your 7,000 lb dual axle RV, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7. These assemblies are side specific and are labeled for you. These will work with your current hub and drum assemblies. For installation and adjustment, you will want the Brake Adjustment Spoon for Drum Brakes # W80630. If you need the mounting bolts for these assemblies, I recommend # BRKH12. If...

  • Installing Bearing Buddy Bra # BB23B
  • As a first step, make sure you are using the correct Bearing Buddy Bra for your application. The # BB23B you mentioned is sized to fit Bearing Buddies that fit hub bores ranging from 2.240 inches to 2.562 inches, or model #s BB2328, BB2328SS, BB2441, BB2441SS, BB2717, BB2717SS, BB2562, BB2562SS, BB2240 and BB2240SS. Applying a very very small bit of grease (I am talking tiny) to the outside of the Bearing Buddy will allow the bra to slide on easier. While sliding the bra into place,...

  • What is the Reaction When Two Greases Aren't Compatible?
  • It is true that some greases do not play well together but this is based on type of grease and not on brand name. When incompatible greases are mixed, the different thickener types with cause the mixture to harden and not release any oil or do the exact opposite and soften too much so all the oil releases. Either can obviously cause bearings to fail quickly. I've attached a chart to assist and have also linked an article to further addess the different kinds of grease.

  • Does Using Bearing Buddy Replace Need for Trailer Hub Grease Seal

  • How to Determine Correct Bearing Buddy for 2011 Newmar Kountry Star 5th Wheel Trailer
  • In order to determine the correct bearing buddy for your 2011 Newmar Kountry Star 5th Wheel, you will need to locate the outer bearing number or take a precise measurement of the hub bore using a digital caliper like # PTW80157. This will ensure you will find the correct buddy bearing. For example, the Bearing Buddy Bearing Protectors # BB2717 fit a 2.717 inch hub bore and works with outer bearing models 14124 and 14125A. It is commonly used with 5,200 - 7,000 pound Dexter Axles, which...
