  • Bearing Buddies for a Boat Trailer with 2.308 Hub Bore

The spinning of the wheel and the centrifugal force then causes the caps to wiggle free and fall out. Given that your hub bore measures 2.308 inches the best match would be a 2.328 model such as # BB2328. It will be a tight fit, which is what you want. To drive them in flush place a block of wood against the Bearing Buddy and tap the wood all around, not just in...

I also might be able to figure out the size you need based on the outer bearing number stamped into the side of the bearing.

If you are pumping your grease into your hub with a grease gun you should note that you should only continue to add grease to the hub until you begin to see the outer bearing move or you see grease seeping through the outer bearing. If you pump the grease slowly and rotate the hub, you should not blow the grease seal. Once you see the grease seeping through,...

  • What Could Cause a Trailer Oil Bath Cap to Crack

It is unlikely that it would get that hot unless there was no oil in the hub so you will want to check that for sure. Also if the caps were over-tightened that could stress them and then, once moving, the centrifugal force could cause further damage. We have several different oil caps, see link, but...

  • What is the Bearing Buddies Bearing Protectors Purpose
  • The Bearing Buddies are designed to protect your bearings by keeping water and dirt out of the hubs and bearings and ensuring there is enough grease inside the hub. If you are not experiencing any problems or visually see any grease leaking out of the hub, then you shouldn't have to repack your bearings regularly. I recommend checking your hubs once a year to inspect the condition of your brakes. If you notice any grease leaking out of the hub, then grease could have been compromised,...

  • Grease Cap Recommendation for a Trailer Hub
  • In order to know what grease cap you would need you need to get an exact measurement with a dial or digital caliper. Tape measures aren't accurate enough since you are looking at the difference of .07 of an inch. If it measures 2.44 the part # RG04-080 would be the correct cap. Most likely this is what you have but I attached a page that has all of the caps we offer, select your outer diameter needed from the filters.

  • How to Choose Correct Bearing Buddies for Trailer Hub
  • You'll want to choose a Bearing Buddy based on the inside diameter of the bore of your hub. You can use a digital caliper to determine this. Also, if you know the outer bearing reference number, we can determine which bearing race is compatible with that bearing, and find the outside diameter of the race, which is equal to the diameter of the hub bore. I've linked you to our selection of Bearing Buddies. The filters on the left side of the page will help you choose the correct Bearing...

  • What is the Outer Diameter and Thread Pitch of Bearing Buddies # BB2441T-SS

The thread pitch is harder to determine. There are approximately 9 threads per inch (only three threads on the actual product) and it is coarse threaded as opposed to fine threaded. These Bearing Buddies are designed to replace Tie Down Turbo Lube oil baths.

  • Finding The Right Size Bearing Buddy For Utility Trailer
  • You'll need to use an accurate measuring device like a digital caliper to measure the inside diameter of the hub bore. A ruler or tape measure wouldn't be accurate enough. I have attached a photo of a hub that shows where the measurement should be taken. If you measure and find the opening to be 1.98 inches then the Bearing Buddy I recommend is part # BB1980A-SS.

  • Grease Cap Recommendation for Hub Bore of 2.3125
  • Sounds like the part # F001926 would work as a standard grease cap as it is designed to fit hub bores of 2.333. However, this is a pretty short cap at only 1.281 inches. The other solution you have would be a Bearing Buddy like part # BB2328. This is designed to fit hub bores of 2.328. Bearing Buddies are similar to grease caps, except they have a zerk fitting on them that allow the spindle to be lubed easily.

  • Using Bearing Buddies on 10K Axle With Oil Bath Hubs
  • Although they're most frequently used on boat trailers, you can use a Bearing Buddy on just about any trailer. You'll want to make sure to install a double lip grease seal, and be careful not to overfill hub. Even with a double lip seal, many folks tend to overfill their hubs and end up blowing out the seal (myself included.) I did some research, and found that the hub bore of the typical 10K axle is around 3.5 to 4.3 inches in diameter, which is larger than any of the Bearing Buddies...

  • Issue with Bearing Buddy Leaking Grease from Overfill Port
  • Generally speaking bearing grease has so little water in it that significant expansion due to freezing temperatures is unlikely. Higher operating temperatures within the hubs while underway would potentially thin the grease but again not cause much in the way of expansion of its volume. Typically Bearing Buddies are used on boat trailers to keep water out of the hubs. Since boat trailers are not often used in extreme cold weather this may be why we have not heard of thermal issues like...

  • Bearing Buddies Needed for Al-KO 7200 lb Hubs
  • To determine which Bearing Buddy you need, you'll either need to measure the hub bore (inside diameter of hub where grease cap inserts) or provide me with the outer wheel bearing reference number. With the bearing number, I can find the corresponding race for the bearing. The race's outside diameter will match the diameter of bearing protector you'll need. I would recommend replacing the grease seal as well. Use a double lip seal to help prevent blow-out. To determine which seal you'll...

  • How to Remove a Bearing Protector from a Trailer Hub
  • Bearing protectors like Bearing Buddies are a very tight fit in a hub. If you cannot wiggle it out by hand then using a rubber mallet and tapping it (not hard but firm) first on the left, then the right, then the top, then the bottom, then repeat, will help loosen it up so you can pull it off. I have included a link to a video as well that should help. Removal of the Bearing Buddy takes place right in the beginning of the video.
