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.

I was ready to order a bearing kit since both bearing numbers matched up and the kit included a Seal plus the Spindle Washer. I was unable to locate a number on the seal so when I called to order I was lucky to have Sandy take my order... she knows her stuff. Sure she could of just took my order and gave me what I asked for but she wasn't comfortable not having a seal number and had me go measure it. As I was doing this I located a set of very small numbers on the rubber lip of the seal. I gave her the numbers off the seal and she was able to cross reference it and discovered it was not the same seal for the kit I was about to order. She found the correct kit had the bearings and seal as an exact replacement. Only "issue" we both thought odd was as a kit it didn't include the Spindle Washer where the other kit did. Not a big deal I just ordered the washers too. 442599

Rolling down the road without issues. I replaced all bearings on my tandem axle boat trailer last year this year I upgraded the surge drums to hydraulic over electric with disc brakes. Definitely a great upgrade would recommend to anyone with drum surge brakes.

The bearing kit for the 6k Dexter axles will be either # BK3-100 or # BK3-110. There are a couple of differences between these two sets. Set # BK3-100 includes a cotter pin and a 10-36 seal which has an inner diameter of 2.250 inches and outer diameter of 3.376 inches. Set # BK3-110 includes...

  • Timbren Axle-Less Suspension System Compatible with Jeep for Matching Trailer
  • For the Timbren Axle-Less kit compatible with the bolt pattern of 5 on 5 like a Jeep, you would need the 2,200 lb capacity # ASR1THDS03. The spindles on the Timbren system are a little larger than their thru-axle counterparts, so the 3,500 lbs # ASR3500S06 will only fit larger hubs that won't have the bolt pattern you seek. Using # ASR1THDS03, you can then use the Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly...

  • Recommended Disc Brake Conversion for 7,000 lb Dexter Axles
  • On your 2018 Montana 3791 RD, with Dexter 7K axles, we do have the parts but not in a kit for axles that large. I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs # K2HR712D along with Bearing Kit # BK3-100. I recommend using grease # L11390 and cap # F001520 instead of doing the oil bath simply because if a seal fails you can melt your bearings and cause more issues than what grease would allow. Then for the electrical aspects, I recommend the HydraStar Electric-Hydraulic...

  • Replacement Bearing Recommendation for Dexter 6,000 lb Axles
  • We have two bearing kits that could fit for your Dexter 6,000 lb axles. The difference is the seal size. The part # BK3-100 is the kit that has the correct bearings and a seal with an inner diameter of 2.25 inches. This is most likely what you need. The other options is the part # BK3-110 which has a grease seal with an inner diameter of 2.125 inches. You would need to measure the outer diameter of the spindle your seal rides on to determine which kit you'd need.

  • Recommended Parts For Adding Disc Brakes To Tandem Trailer With 6,000-lb Axles

First, you can use the Kodiak Disc Brake Kit, part # K2HR526D. This includes the hub and rotors for one axle. You will also need a bearing kit, part # BK3-100 for each wheel. Since the lug nuts, part # CE11051 are not included, you can purchase them separately. For a grease cap you can use part # F001520. For a 24-ft long brake line kit...

  • Bearing and Seal Recommendation for a 6k Dexter Axle
  • You will need to pull off your current hubs to remove the bearings and seal to get the numbers so that we can determine for sure what you would need. But MOST likely the correct kit you would need would be the part # BK3-100. This kit comes with outer bearing # 15123 and inner bearing # 25580 and seal 10-36 # RG06-070. This is the most common bearings and seals used on 6k Dexter axles, but you need to verify your bearing and seal numbers to be certain.

  • How To Replace Bearings and Seals on Unknown Brand and Size Trailer Axle
  • To find the proper bearings you will need to remove your current hubs. Once you remove the hubs, you can remove the current bearings and look on the face of both the inner and outer bearing for a number printed on it. If you give me those numbers, I can help you get the replacements you need that may or may not have the same number. If you can't get a number off the bearings, then you will need to take a digital caliper # PTW80157 and measure the spindles. The spindles will need to...

You did a great job of providing me with lots of information, which makes my life easier but in this case I couldn't find anything. You'll need to pull one of your hubs, and get the reference numbers from the inner and outer bearing, from which we can determine which races and seals are needed. If you can't make out the reference numbers, you'd...

  • Recommended Disc Brake Kit for Airstream Tandem Axle Trailer
  • To convert to disc brakes, you will need to check the bearings on your current hubs. If you pull the hub you should find on the inner and outer bearing a number printed on each. Those numbers will help to confirm the fit on your spindle. If you can't find this number, then you can measure the spindle with a digital caliper like # PTW80157 where the bearings would rest on the spindle. I've attached a photo to assist.

  • Hub Recommendation for an Old Mobile Home Axle
  • It sounds like you have found the correct hub and drum assembly. The Trailer Hub and Drum # 42656 that you referenced recommends inner bearing 25580 and outer bearing 15123 which are the exact measurements you gave.

  • For a Lippert 6k axle you have two options. The part # BK3-100 and the part # BK3-110. The difference would be the size of the inner diameter of the grease seal. The part # BK3-100 comes with seal that has inner diameter of 2.25 inches and the part # BK3-110 comes with seal that is 2.125 inches. For a 7k axle by Lippert you would want the part # BK3-200 if the seal diameter needed is 2.25 inches or part # BK3-210 for inner diameter of 2.125 inches.

  • What Parts Needed When Replacing Disc Brake Rotors # KHR12D on Boat Trailer
  • When replacing the disk brake rotors on your trailer it is recommended that you also replace your bearings, races and seals at the same time.

The bearing kit for this rotor is part # BK3-100. I have included an article that covers the process of replacing bearings, races and seals on a trailer hub. The Kodiak...

  • Replacement Hubs for a 2003 Venture Boat Trailer Model 2250 with 6-Lug Hubs

Since you have a boat trailer you might be interested in Kodiak hub # KH42655S which is stainless steel so it won't corrode. It uses inner bearing 25580 and outer bearing 15123. Another option is hub # 8-213-5UC1 which uses the same inner bearing but a different...

The weight threshold at which brakes are mandated varies by state, so you might want to check that with your state police or highway patrol. If you decide on an idler hub (no brakes), I'd recommend the # 42655UC1 hub from Dexter Axle. The bearings, races, grease seal, lug bolts and grease cap are included. The hub will have more than enough capacity for your application. This hub would use the # R50642 spindle. For...
