Expert Answers about Grease Caps


  • What is the Depth of Bearing Buddy BB1980A-SS One Installed in Hub Bore
  • I went to our warehouse and pulled a sample of the Bearing Buddy kit # BB1980A-SS that you referenced so I could measure it for you. From the shoulder (the point that remains outside the hub bore) out to the outside edge of the stainless housing the depth is 37mm or 1.46-inches. The flexible plastic dust cap will add roughly another 3mm or 0.12-inches to that depth if installed on the stainless housing.

  • Can Bearing Buddy Bearing Protectors Be Used For Hub Bore that Measures 1.99 Inches
  • I went to our warehouse and measure the Bearing Buddy protectors, part # BB1980A-SS that would be the closest size you need. They all measure 1.983 or 1.982 inches diameter. If you measure your inside hub bore and find it is smaller than the 1.99 inches you asked about then the # BB1980A-SS would work for you.

  • Can Air Escape Trailer Hub Seals When Filling with Grease with Bearing Buddy
  • Grease seals are not air tight so the air would be able to escape as you fill the hub up. They are tight enough to keep the grease in though. Grease does breakdown over time so you do occasionally need to add more. The grease seals are also not totally sealed. They do a pretty good job sealing but in general contaminants can still find there ways in.

  • 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.

  • Where to Measure to Pick Out Bearing Buddy for a Trailer Hub
  • Actually the dimension you are looking for when picking out a Bearing Buddy is on the hub and not the spindle of the trailer. You need to remove the cap of the hub and then measure the diameter of the bore with your mic and that is the dimension needed. See picture. The part # BB1810 that you mentioned is the correct Bearing Buddy if you have a bore of 1.81 inches.

  • 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.

  • 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.

Also, when adding grease, pay close attention to the piston surrounding the grease zerk....

  • How To Determine What Bearing Buddy Bearing Protectors Will Work With Trailer Hub
  • A tape measure is really not the best way to measure the hub bore on your trailer to find the right size Bearing Buddy.

If you find your hub bore measure 1.781 inches then part # BB1781 would work great for your trailer. If your hub bore measures 1.980 inches, part # BB1980A would be a great fit.

  • Bearing Buddy and Spindle Grease Seal Set Recommendation for 3,500 Pound Axle Trailer

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.

Or, you could use a digital caliper like # PTW80157 and measure the inside diameter of the hub bore, as...

  • 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 # PTW80157. 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.
