When to replace it?

Replace the dust seals whenever you replace the oil seals, and as soon as they are cracked. Check the size (in the name) or the original part number.

Fitting tips

1. Lift out the old dust seal with a plastic tool, without scratching the inner tube.
2. Clean the groove in the fork leg and the tube.
3. Grease the lip lightly and press the new one in flat, by hand.

Frequently asked questions

Is a new dust seal enough to stop a leak?
No: the leak comes from the oil seal. The dust seal only protects it from dirt.
