Expert Answers about Grease Caps


  • Bearing Buddy Recommendation for PWC Yacht Club Trailer Model WC112
  • To know which Bearing Buddy will work for your PWC Yacht Club Trailer, you need to get a measurement that is as accurate as possible. I recommend using a set of digital calipers like the # ALL641130 to measure the inside of the hub opening the Bearing Buddy will be used on. Once you find the inside measurement of your hub, you will be able to tell which Bearing Buddy will work. If your hub is 1.98 inches, part # BB1980A-SS will work well for you. Another way to find out what will...

  • Which Oil Bath Cap Do I Need on a 2003 EZ Loader Trailer
  • In order to determine the correct oil bath cap you'll need to measure your hub bore or find the weight capacity of your axle. If you have a 3500 lbs. axle or a 1.98 inch hub bore you will want part # XLPROLUBE1980 or # XLPROLUBE1980KIT for a kit that includes caps, seals, and oil. For 5200 or 6000 lbs. axles that have a hub bore of 2.440 inches you will need # XLPROLUBE2440 or # XLPROLUBE2440KIT for the kit.

  • Replacement Boat Trailer Hub with Inner Bearing L44643
  • Repairing your boat trailer doesn't have to be a nightmare. I will help you to make it a sweet dream instead! You really should have both bearing numbers to ensure you get the right hubs for your trailer. The good news is you have to take the hub off anyway if you are going to replace it. Both of your bearings are likely L44643 but to be sure I would like to know the outer bearing number as well. If they are indeed both L44643 then hub # 8-258BTUC1 will fit if the wheel bolt pattern...

  • How to Pick Out Replacement Grease Cap for Trailer Hub

  • Which Bearing Buddy Do I Need on My Utility Trailer
  • Since the 1.98 inch is just slightly too large then more than likely the 1.968 inch # BB1968 is going to be your fit. To find out for sure which Bearing Buddy you need you can check your bearings. If your outer bearing is M12649 or 07100 then you need the 1.968 inch. If you have outer bearing models L44643, L44649 or L44640 then you will need a 1.98 inch Bearing Buddy # BB1980A. Or if your outer bearing is model 09067 then you need the 1.938 inch # BB1938.

  • 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 # ALL641130 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...

  • Replacement Bearing Buddy Grease Caps for Boat Trailer Used in Salt Water
  • It is possible to over-fill a hub when a Bearing Buddy is in use because they make it so easy to pump in wheel bearing grease. Usually the victim of an over-filled hub is the inner grease seal, however, not the Bearing Buddy itself. You'd blow out your inner seal long before you'd push off a Bearing Buddy in normal circumstances. You may have installed the wrong size, or not fully seated them in the hub bore. If your inner grease seals are still intact (no obvious grease leakage) then...

  • Do I Need To Grease my Bearings Before or After my Road Trip
  • You will only need to add grease if it is needed. If you too much grease you will blow out the grease seals which will end up as a mess. Bearing Buddies have a spring-loaded piston that keeps pressure on the grease in the hub. The closer the piston is to the outer edge of the Bearing Buddy, the more compressed the spring is and the more full the hub is. You should be able to look at your Bearing Buddy # BB1781 and see how full it is to determine if you will need more grease for your trip.

  • What Causes Grease On the Inside of Boat Trailer Wheels
  • The guy you were speaking with was telling the truth. If the Bearing Buddies are overfilled, you will indeed blow out the grease seal. The excessive pressure will push the grease out through the rubber portion of the seal. Using a double lip grease seal that has a radial spring inside it which makes the rubber seal grip the spindle more tightly can help reduce the likelihood of the seal blowing out. Also, when adding grease, pay close attention to the piston surrounding the grease zerk....

  • How to Pick Out Bearing Buddy for a Trailer Hub
  • Sounds like you are looking for a Bearing Buddy. But nothing we offer is for that small of a size. Not even standard grease caps are offered in that size either. It is possible you aren't measuring the correct area though. In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver...

  • Bearing Buddy and Spindle Grease Seal Set Recommendation for 3,500 Pound Axle Trailer
  • Typically, 3,500 pound axles use an inner bearing # L68149. However, it is a good idea to double check that this is the inner bearing on your trailer. For a trailer that has an inner bearing of L68149 with a 1.980 Bearing Buddy, you will want to use the Spindle Grease Seal Set # BB60002. It looks like you previously ordered the Titan Disc Brake Kit # T4843100. This kit uses the L68149 inner bearing. For these disc brakes with the 1.980 Bearing Buddy, the # BB60002 grease seal set will...

  • How to Determine What Replacement Grease Cap is Needed For a Premier Dual Axle Dump Trailer
  • I'm assuming you're speaking of a grease cap that's driven into the hub bore. Grease caps are available in different sizes. There are two good ways to determine which size you need. One is to locate the reference number off of the outer wheel bearing. Finding the outer wheel bearing would lead me to the reference number of the race, which would lead me to the grease cover diameter. Or, you could use a digital caliper like # PTW80157 and measure the inside diameter of the hub bore, as...

  • How to Pick Out a Bearing Buddy for a Echo ATV Trailer

  • Troubleshooting a Loose Bearing Buddy Fit
  • Unfortunately, the bearing buddy cannot be expanded in any way. What you would want to do to ensure a good fit for your bearing buddy to the hub would be to measure the inner diameter of the hub bore with a dial caliper # ALL641130. Once you obtain the proper hub bore diameter then you will want to choose a bearing buddy based on that measurement. The next size up bearing buddy for your hub would be the # BB2047. I have added a few videos for your convenience.

  • Solution for Bearing Buddy that Won't Accept Grease
  • Moving the wheel could help allow the grease to make its way into the hub of your trailer, but it could also be a clogged zerk fitting. There isn't an easy way to unclog zerk fittings so you may just need to replace the Bearing Buddys with the part # BB1980A. It could be dried up grease on the other side of the Bearing Buddy too. You would want to remove them and try cleaning them from the inside.

  • Do Bearing Buddies Allow Air to Escape as they Add Grease to Hub

  • XL Kodiak ProLube 1980 Castle Nut Washer Recommendation
  • Do you have an overly large castle nut washer? It seems odd that the washer is too big to fit in the cap of the # XLPROLUBE1980KIT. Since this kit is designed for 3.5k axles the correct replacement washer should be the # 5-23. This washer should be very similar in size to the castle nut.

  • Measuring a Trailer Hub to Find the Right Bearing Buddies
  • Are the hubs the same part? Or different parts or manufacturers? Is the lo0ose side hub damaged at all? That is strange that the 1.781 would fit one side and not the other. To determine if # BB1810 will fit I recommend measuring the hub bore ahead of time. The measurement has to be as accurate as possible so use calipers, such as # PTW80157, to take the measurement.

  • How to Measure a Trailer Hub or Dust Cap to Find the Right Replacement Dust Cap
  • You can measure either the outer diameter of the part of the dust cap that fits into the hub OR the inner diameter of the hub where the dust cap goes using calipers such as # PTW80157. Calipers are needed because the measurement has to be as accurate as possible. I also might be able to figure it out based on the outer bearing number which you should be able to see without taking the hub off.
