Expert Answers about Bearing Buddy

  • Recommended Bearing Buddy and Bearing Kit for Malone MicroSport Trailer
  • The Malone MicroSport Trailer # MPG460G does have the 1.98 inch inner diameter hub. I confirmed this with the manufacturer. To add bearing buddies, you simply need the # BB1980A for chrome or # BB1980A-SS for stainless steel. You will not need to replace the bearings to install these caps. You can simply use the LubriMatic Economy Size Mini Grease Gun # L30100 and add the marine trailer wheel bearing grease # L11399 that matches what the axle comes with. When installing these, you...

  • Bearing Buddy to Replace Tie Downs Turbo Lube Oil Bath 48394 Cap?
  • Yes, Bearing Buddy # BB2441T-SS replaces Tie Down's Turbo Lube oil baths. I ran out to the warehouse and double checked that the outer dimension of the threaded portion matches the 2.33" of your Turbo Lube 48394 cap. You will want to remove the oil from the hub using shop towels and a mild detergent. Let them dry completely before packing them. Bearing Buddy also recommends using a High Performance Silicone Gasket Maker like Loctite's # LT37467 for the installation.

  • How to Measure Hub to Select Bearing Buddy Grease Cap
  • I reviewed your photo and other photos of your H-F 90154 folding trailer and it appears to have grease caps far larger than 0.984-inches. It sounds like you were quoted a bearing dimension, not a grease cap dimension. What I suggest you do is remove one of the standard grease caps and measure the inside bore of the hub. You will need a caliper like # PTW80157 to measure to the nearest thousandth of an inch, e.g. 1.234-inches. You can then use the linked page to check for a Bearing Buddy...

  • Bearing Buddy That Fits 2.7 Inch Hub Bore
  • We do have a Bearing Buddy which fits a similar dimension as the 2-3/4" you referenced but I do recommend using a digital caliper and measuring your hub bore size to the thousandths of an inch to ensure you get the correct fit. For a 2-3/4" hub bore the closest fit we have are Bearing Buddies that fit a 2.717" hub bore, the Bearing Buddy Bearing Protectors - Model 2717SS - Stainless Steel # BB2717SS and the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated # BB2717. I...

  • How to Keep Grease From Coming Off My Outer Bearing
  • I recommend using a Bearing Buddy to keep the grease in your hub and on your outer bearing. Bearing Buddies replace the grease cap in the axle hub and prevents wheel-bearing failure. They also keep water and dirt out of hubs and bearings. You will be able to use the same grease you are using and will need a grease gun similar to # L30132 to load grease into the Bearing Buddy. All the grease will end up flying off your hub it is not contained. The key is to pack enough grease into the...

  • Replacement Dust Cap or Grease Cap for Trailer
  • We do have replacement dust caps. You will simply need to use a digital caliper like # PTW80157 to determine the size needed. I've linked the page to all your options to assist. I've also linked the page to the bearing protectors that have the integrated grease zerk to maintain them.

  • Recommended Bearing Buddy Kit for Carry-On 5X8G Trailer
  • Based on my research, your Carry-On 5X8G Trailer uses hubs that have a 1.98 inch diameter pilot hole. With this in mind, the correct Bearing Buddy Kit will be one that fits 1.98 inch hub bores like the part # BB1980A-SS. These will replace the grease cap in the axle hub and prevent wheel-bearing failure by keeping water and dirt out. They will also provide easily accessible grease fittings and makes adding grease to the bearings quick and simple. I have included a short installation video...

  • Shorelander Wheel Hub Stud Recommendation

  • Recommended Bearing Buddy for 2 Inch Hub Bore
  • We have a few Bearing Buddy Bearing Protectors available that are designed to fit a hub bore of around 2 inches in diameter, but not one that measures 2 inches exactly. I recommend using a digital caliper like # PTW80157 so you can take an exact measurement of your existing hub bore. For example, the Bearing Buddy Bearing Protectors # BB1980A-SS are designed for 1.980 inch diameter hub bores while the Bearing Buddy Protectors # BB2047SS are compatible with hub bores that have a diameter...

  • Compatible Bearing Buddy to Fit Axle Hubs with Reliable Oil Caps Installed
  • When trying to remove the broken Reliable oil cap you may need to use a hammer and a long flat head screwdriver. Placing the screwdriver head on the outer edge of the cap, lightly tap the screwdriver to force cap to turn in the desired direction to remove from the hub. Be careful not to put the screwdriver inside hub to try to remove the cap. It could slip and damage the threads on the inside of the hub. To make sure you will receive the correct Bearing Buddy for your trailer's hubs,...

  • How Much Grease Should be Added to the Bearing Buddy Bearings
  • In order to add grease to a bearing buddy such as the Bearing Buddy Bearing Protectors part # BB1980A you will need a grease gun like part # ALL940798 and the appropriate bearing grease like part # L10320. Once you have obtained both the grease gun and grease you can fill the bearing buddy. 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...

  • Bearing Buddy Grease Caps for Hub Bore Dimension of 2.05-Inches
  • Bearing Buddy bearing protector grease caps are made in many sizes and we carry those most often used in recreational trailering. You can see all Bearing Buddy parts we have by clicking on the page I linked for you. Bearing Buddy grease caps are made both with and without threads so you'll want to check your hub bore to see if it is threaded or not. Click on the appropriate type on the page. For a dimension of 2.05-inches you can use a Bearing Buddy kit in size 2.047-inches, such...

  • Is There a Bearing Buddy that is Threaded Comparable to a 2240?
  • I contacted Bearing Buddy to see what threaded cap they recommend for your application to convert from oil bath to grease. They said that the Bearing Buddy Bearing Protectors, # BB2441SS, is most likely the application for your trailer based on the 2240 question. This Bearing Buddy threaded grease cap has 12 threads per inch, as does # BB2080T-SS, but there are other threads like the # BB1980T-SS which has 24 threads per inch.

  • Replacement Spindle Grease Seal Set for L44649 Bearings and 1.980 Hub Bore
  • I tried to find your previous order with us to see what you already have but I was unable to. Regardless, the correct seal set for your # L44649 bearings with a hub bore of 1.980 is # BB60005. These seals are neoprene with greased stainless steel rings like you're looking for.

  • Bearing Buddy and Standard Grease Caps to Fit 1.98-Inch Hub Bore
  • All Bearing Buddy bearing protectors have the same depth, just different diameters. Also, some are threaded to fit threaded hubs while others are not. If your spindles have a grease zerk fitting on the end you will not need to use a Bearing Buddy; that grease zerk means you have EZ-Lube spindles which provide an alternate way to maintain your hubs grease level. For such spindles use part # RG04-040 If it is the actual castle nut that hits the inside surface of the Bearing Buddy then...

  • Bearing Buddy for 2-3/8" Grease Cap
  • A measurement of 2-3/8" is equal to 2.375" and there are a number of bearing buddies that are close to that measurement. In order to determine the exact replacement you need, you'll have to use a digital caliper such as # PTW80157 and measure your hub bore for the exact measurement. Your other option would be to take a look at your outer bearing, as that will also tell you what you'd need. Bearing Buddy # BB2240 fits a 2.240" hub bore and works with 1700 series outer bearings.

  • Recommended Seal For Bearing Buddy Protectors
  • The Bearing Buddy Bearing Protectors - Model 1980A-SS w/ Auto Check - Stainless Steel (Pair) # BB1980A-SS are designed for that blue seal to expand and eventually have visible grease around that edge. I've attached a video that shows this installation and grease application for you. The grease needing to be applied almost every trip is not normal, so I recommend the Spindle Grease Seal Set # BB60002 to contain your grease with a tight seal intended for this application.

  • Bearing Buddy Recommendation to Replace Trailer Hub Cap Measures 1-7/8 inch
  • Just under 1-7/8 inch would put you very close to what the Bearing Buddy part # BB1781 is designed to fit as it fits hub bores that measure 1.781 inch. Ideally you'd verify this with a digital caliper like part # PTW80157.

  • Will the 2.047 inch Bearing Buddy Fit a Bore Size of 2.012 inches
  • I believe that the bearing buddy that you hub bore diameter that you saw was the 2.240 inch size, part # BB2240, which will be too big to fit in your hub bore size of 2.012 inches. The next step up from the # BB1980A that you purchased (which fit hub bore size 1.980) will fit the hub bore size 2.047 inches and is part # BB2047. Since you want the fit to be as accurate as possible this size will be too big. I called Bearing Buddy and my contact confirmed this. Custom-built trailers can...

  • Replacement Dust Cap/Grease Cap For Older Boat Trailer With Cap Measuring 2.312 Inches
  • For your boat trailer I recommend the Bearing Buddy Bearing Protectors - Model 2328 - Chrome Plated (Pair) # BB2328. These are designed to have extra grease and keep water out of your hubs so they can be completely submerged. If you are looking for a standard grease cap, the closest we have to your 2.312 measurement is the Fulton Grease Cap - 2.333" Outer Diameter - Drive In # F001601 which should work.

  • Bearing Buddy Recommendation for Threaded Hub Bore
  • Bearing Buddy does have options for thread hubs like what are seen on oil bath setups. We only have three options though: # BB1980T-SS for a 1.980 inch diameter # BB2441T-SS for a 2.441 inch diameter # BB2080T-SS for a 2.080 inch diameter

  • Installation Method for Parts Included in Bearing Buddy Spindle Grease Seal Set # BB60002
  • The flat steel washers included in the Bearing Buddy Spindle Grease Seal Set # BB60003 are the first part of the 4-piece assembly to be installed on each spindle. These are followed by the L-shaped steel seal ring, then the O-rings. The actual large grease seal itself is installed into the hub's bore and then mates up with those other three parts already on the spindle. The linked video illustrates the last 3 items but does not the flat steel washers.

  • Difference Between Bearing Buddy 1980 Models
  • The model 1980 Bearing Buddy simply means that they fit a 1.980 inch hub bore. There is one difference of note between Bearing Buddy Bearing Protectors # BB1980A (Chrome Plated) or # BB1980A-SS (Stainless Steel) and the Bearing Buddy Bearing Protectors # BB1980T-SS which is that the latter - with the "T" in the part number - means that it is threaded and fits internally threaded hubs.

  • Bearing Buddy Spindle Seal Kit For Hub Using L68149 Inner Bearing
  • The Bearing Buddy Grease Seal Kit you referenced, part # BB60002 would be the appropriate replacement seal for your hub. It is compatible with your L68149 inner bearing and is the proper replacement for your existing 10-19 seal. The two most common causes of seal failure are 1) Using a single lip seal instead of a double lip and 2) Overfilling the hub (or a combination of the two.) A double-lip seal incorporates a spring into the seal, providing a tighter seal around the spindle. To...

  • How to Measure to Determine the Correct Grease Seal on a Trailer Hub
  • I could not find any information on the seal number you listed so yes, you will need to take an accurate measurement of the outside diameter of your existing seal, or the inside diameter of the mounting surface for the seal in the hub. You will also need an accurate measurement of the spindle at the seal surface. I have posted a photo to show the dimensions you will need to measure. A dial caliper will provide an accurate measurement to determine the correct seal for your hub and spindle. I...

  • How Does the Spindle Seal Set part # BB60003 Install
  • I attached a picture that shows a diagram for how the Spindle Seal Set part # BB60003 would install on a spindle. Installing the shoulder ring first gives the O-ring something to press against so that it can seal better. Reversing the order would defeat the purpose. I attached the demo video you referenced as well.
