Bearing Buddy installed diagram

Bearing Buddy Operation

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.

These bearings Caps look great. I looked forward since I received my order. Unfortunatly I only installed these Bearing Buddy protector grease caps last week. I tried last spring before to launch the boat, but the diameter of the caps was a little to large for my hubs. I brought them to a machine shop with one of the old dust caps. 445954

  • Recommendations for Bearing Buddies and Grease on Dexter 7,000 lb Axle
    Bearing Buddy Bearing Protectors like # BB2717SS will not work with E-Z lube axles unless you remove the grease zerk fitting like you mentioned from the spindle. Once that grease zerk is removed, then the Bearing Buddy will work as intended using the spring loaded design and integrated grease zerk to keep the bearings well lubricated and maintained. When adding grease, you need to be careful not to mix styles of grease as they aren't compatible in most instances. So you will either...

  • Should Bearing Buddy System Replace Sure Lube Hub Setup on Trailer
    By Sure Lube you mean like an EZ Lube setup that has zerk fittings on the ends of the spindles to grease through the middle of the hub? That's what I was able to find when Googling your setup. If so, you can install a Bearing Buddy over this style of hub but it's typically better to stick with the EZ Lube setup as it applies grease in a way that's easier to reach the bearings. If you can get me the diameter of your hub where the grease cap fits I can get you a cap with a removable center...

  • Oil Bath or Grease for HydraStar Disc Brake Kit with Actuator for Tandem Axle Trailers
    In regards to the bearings, trailer bearings nowadays are generally made overseas; there may be some exceptions here and there, but they generally aren't standard trailer bearings. The bearings and seals that come with the HydraStar Disc Brake Kit with Actuator for Tandem Axle Trailers # HSE7K-T1 are of the highest quality and you won't have any issues. As far as changing from grease to oil bath, that is not recommended for trailer hubs. Oil bath hubs can be problematic because they...

  • Bearing Buddy That Fits 2.7 Inch Hub Bore
    We do have a Bearing Buddy which fits a similar dimension as the 2-3/4" you referenced but I do recommend using a digital caliper and measuring your hub bore size to the thousandths of an inch to ensure you get the correct fit. For a 2-3/4" hub bore the closest fit we have are Bearing Buddies that fit a 2.717" hub bore, the Bearing Buddy Bearing Protectors - Model 2717SS - Stainless Steel # BB2717SS and the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated # BB2717.

  • Availability of Bearing Buddy to Replace 4 Inch Diameter Oil Cap
    The largest Bearing Buddy available is a 2.717 inch diameter # BB2717SS (stainless steel) or # BB2717 (chrome plated), which means you wouldn't be able to convert your oil bath hubs to greased ones. However, we do carry the direct replacement for your Dexter Oil Cap Kit number K71-148-00, the Redline # RG04-270, which includes the cap, gasket and plug and is designed for 9K-15K Dexter Oil Bath Hubs like # K08-288-90.

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
    Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
    Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • Replacement Bearings and Seals for Converting 8K Oil Bath Dexter Axle to Grease
    I believe I was able to find the bearings and seals that you need, but you'll want to double check on your end by removing the hub and looking at part numbers just to make sure. Inner Bearing - # 25580 Inner Race - # 25520 Outer Bearing - # 02475 Outer Race - # 02420 Grease Seals - # RG06-070 (2.250" ID and 3.376" OD) When it comes to the oil bath caps from what I could find yours should be part # RG04-230 which has an OD of 2.875" and nothing we have is that fits that.

  • Replacement Brake Shoes for Dexter 12x2 Nev-R-Adjust Brake Assemblies
    Assuming that you have the Dexter # 23-458 and # 23-459 Nev-R-Adjust brake assemblies, you'd need the # K71-676 for the right side and # K71-675 for the left side. The correct Bearing Buddy for you will depend on which outer bearing your hubs use. 15123 or 14125A are the most common. If the outer bearing is 15123, you'd use # BB2441SS. If you can't make out the reference number on the outer bearing, you can simply measure the inside diameter of the hub bore. For the 15123 outer bearing,...
