Product Description

?

This O-ring creates a tight seal within the spindle lock assembly, helping prevent oil leaks while keeping dust and debris out of the gearbox. Made from durable rubber and measuring approximately 0.25 × 0.25 × 0.25 inches, it supports reliable protection and long-lasting performance. Replacing a worn or damaged O-ring helps maintain proper sealing, protect internal components, and ensure smooth tool operation.

Pin cap came off the pin that holds the gear while removing or installing grinding discs. The reason is that the hole Where the pin goes through the housing was warn.

Removed the guard, then removed the 4 phillips screws from the housing. I Put a little grease on the gears. I Seated the o-ring inside the housing (seat is Inside where the pin goes through the housing) Then I put the pin in the hole (grooved end out) with a small amount of grease on the pin to hold it in place while you replace the housi ng. Once you screw the housing down, then rotate the shaft to be sure the pin is not in the locked position so that it is protruding from the hole as far as it can. Place the spring over the pin, and place the cap on, aligning the hole over the pin, then take the adjustable pliers and clamp down until the cap pops onto the pin. Reattach the guard.
