  • Gearbox clutch neglect

    Recently replaced wormshaft and associated clutch parts on an A model that had an unbearable chattering noise coming from the clutch.

    The pictures tell the story. Clutch plate bearing seized causing the boss to rotate on the disc. Pin in cone that locks the boss is worn down and obviously been grinding into the boss. Friction material worn almost down o the rivets. Rivets broken allowing them to come into contact with disc. Wormshaft spline badly worn, disc spline so badly worn its close to slipping.

    Yup, neglect pretty well sums that up.

      What I found interesting was it's not often you find so many faults in the one assembly. To have so many critical components all failing at the same time is a first for me.

        Amazing that these machines will still run with so much neglect..
