  • Insertion of any dust cap can be painful.
  • Using a pipe of the correct diameter will significantly improve the ease of which the dust cap inserts.
  • 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. Extra hitting can make the grease cap, 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 from the bearing cavity. Your grease cap should be inserted dry.
  • 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.
  • It never re-enters the bearing cavity one caught in the grease cap.
