2t Parallel Galvanised Australian Dust Cap fits 63.5mm or 2.5 inches

2t – Parallel Galvanised Australian Dust Cap fits 63.5mm or 2.5 inches.

Dust caps are a pressed metal compression fit. Compression fit means the cap is a little larger than the hub opening. The lip on the cap is squeezed as it is held into position.

Caps lose compression after multiple uses. When this occurs, replace the dust cap on your trailer.

It fits the following Hubs and bearing sets;

  • Parallel
  • Two Tonne

Some hubs do not have machined chamfers in the boss and rear of the hub. Insertion can be brutal. Using a pipe of the correct diameter can significantly improve the ease with 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 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 from the bearing cavity. Your grease cap should be inserted dry.

Grease is generally in oversupply during the greasing process. The 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 once caught in the grease cap.

What is the purpose of the grease cap?

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