59mm dust cap 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 loose if hammered into position too frequently even on the first insert.

Once the dust cap is home, stop hitting it. An extra hit can actually make it loose-fitting.

Question: Should I fill my grease cap full of grease.

Answer: No, the purpose of the grease cap is to catch excess grease when the bearing cavity is pressurised. Pressurisation occurs during rotation at high speed.

Ideally, the grease cap should be inserted dry, however, grease is generally in oversupply during the greasing process.

Grease will exit the bearing cavity at high speeds and during the initial heating and cooling process. Note: Grease never re-enters the bearing cavity one caught in the grease cap.

What is the purpose of the grease cap?

  • To catch grease?
  • Or to prevent the ingress of dust?
