Bearing Buddy

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…

The portion you need to measure is not the cap, but the the hub bore. Remove the grease caps and measure the diameter of the opening the caps occupy. This is the hub bore. You will need an accurate measuring devices like a set of dial calipers that…

Hey Erick, the correct size Bearing Buddy to use with the axle part #e75SR is part #BB2441 which has an outer diameter of 2.441 inches.

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

It does sound like your bearings are a #L44649 (1.063" inner diameter). If they are original to the trailer they may be pretty worn, which is why your measurements may be off by a few hundredths. Also the seal #34823 that can be used with the…

You'll basically just need to remove as much of the oil from your hubs as you can and then pack them with grease instead of oil. Oil seals and caps seal better than grease seals and caps so to make the conversion you want to make is not hard at…

Thank you for providing all the information. If you are going to replace your entire idler hub you would want the Stainless #KH84545S or Galvanized #DE36VR idlers hubs since its on a boat trailer. These will come with the Inner Race #L68111 and Outer…

Hey Jon, so the Bearing Buddy seal kit part #BB60002 that you referenced is the correct fit based on your bearing numbers.

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…
