American Bearing Buddy ™ fits 1.98″ American Hubs.
For a tight fit, clean then coat the contact surface with lock-tite.
Some hubs do not have machined champers in the boss and rear of the hub.
Insertion can be difficult. Using a pipe of the correct diameter can greatly improve the ease of which the dust cap can be installed.
Dust cap can become lose if hammered into position too frequently even on the first insert.
Once the dust cap is home, stop hitting it. The extra hit can actually make it loose-fitting.
Note: It is essential Locktite is applied when bearing buddies are inserted into hubs to help prevent them becoming dislodged during transit. Some hub bosses can vary by as much 0.2mm. This variation in some manufacturers hub sizes can cause a loose fitting bearing buddy. We recommend a medium strength locking compound on all bearing buddies.
Question: Should I fill my grease cap full of grease.
Answer: No, the purpose of the grease cap is to catch excess grease from the bearing cavity. Your grease cap should be inserted dry.
Generally, grease is oversupplied during the greasing process.
Grease will exit the bearing cavity at high speeds and during the initial heating and cooling process. Grease never re-enters the bearing cavity one caught in the grease cap.
Care must be taken when loading grease through the grease nipple.
