  • Drive pin removal

    Does anyone have a good method for removing the drive pin from the gearbox clutch cone? I have a few that have worn pins and I would like to replace them.

    If the pin has enough meat left you can clamp it very tightly with some vice grips and clamp the disc in a vice. Using a claw hammer against tip of the vice grips you can tap the head of the claw hammer to lever the pin out.

    If there isn't enough of the pin left you can drill a smallar hole on the opposite side of the cone directly behind the pin and tap it out with a pin punch.

        Good suggestions from James.
        I have previously drilled the pin out from the inside of disc, punched the pin out from the back and then enlarged the hole by drilling it out and then punching a roll pin into the disc.
        The locking of the boss to the disc ensures the clutch plate bearing rotates rather than the boss rotating on the disc.
        The clutch components will work fine without the disc pin, maybe a little noisy if the boss is indeed rotating on the disc. If you have a good clutch plate bearing and you don't over lubricate the boss, the pin is not essential. Preferable but not essential.
