Replace your existing grease cap with a Bearing Buddy to ensure a safe, easy way to monitor and control the level of grease in your axle hub. To adjust the amount of grease in the hub, use a grease gun to add more through the appropriate fitting. Adding grease moves the Bearing Buddy spring-loaded piston outward 1/8".

The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The interior of the Bearing Buddy is pressurized, preventing water from entering the barrel and diluting the grease.

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 can damage the inner seal.

You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

The product is good, but he shipping leaves something to be desired. More communication would be better, as well as a better shipping process. I suppose you get what you pay for when it comes to shipping.23975

• What Size Bearing Buddy Is Needed For A Hub Bore Size Of 1.940 Inches On A 1951 Utility Trailer
  
• I have a Bearing Buddy Bearing Protector, # BB1938, which fits a 1.938 inch hub bore. This would be the closet to your measurement of 1.940 inches and should work in your hub. The next closest size I would have is the Bearing Buddy Bearing Protector, # BB1968, it fits a 1.968 inch hub bore. The Bearing Buddy Bearing Protector, # BB2047, you have referenced fits a 2.047 hub bore, which would be too big for your trailer.

• Recommendation for a Bearing Buddy for a 2.044 Inch Trailer Hub Bore Diameter
  
• For a hub bore of 2.044 inches, you will need a Bearing Buddy that is slightly larger, like # BB2047, that you have referenced. You can also use Stainless Steel model # BB2047SS.

He goes over some of the various methods of securing them into the hub. It w
