Dexter Dust Cap
Like most dust caps, the Dexter dust cap is a compression fit. A compression fit means the lip of the dust cap is larger than the hole it fits; therefore, it must compress to lock into the hole.
What size Dexter Caps are available
- 1.98 inch Metal Cap (50mm)
- 2.441 inch Metal Cap (62mm)
- 2.75 inch Metal Cap. (39.85mm)
Some Dexter hubs do not have machined chamfers in the boss and rear of the hub.
Insertion can be difficult. Using a pipe of the correct diameter can greatly improve the ease with which the dust cap can be installed.
Dust cap can become lost if hammered into position too frequently, even on the first insert.
Once the dust cap is home, stop hitting it. Extra hits 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 from the bearing cavity.
Generally, grease is 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 finding its way into the grease cap.
What is the purpose of the grease cap?
- To catch grease?
