The clutch stopped working last summer and I just got around to pulling the gearbox to check out why the shaft would only move an inch either way. I figured the notorious taper pin had broken but years ago I had done the 3/8 bolt fix so I thought the shaft may have actually broke! It turned out that one of the crosshaft bushings had come loose and worked it's way out of the housing and along the shaft. This caused just enough play (along with a worn release bearing) that when the clutch was depressed the release bearing sleeve slipped off the input shaft and jammed so could not return. There was a lot of grease on the shaft ends so I may have been overzealous with grease....maybe even forced the bushing out with grease??? Anyone heard of this? I have a spare shaft that is in good shape...old shaft has significant wear. One of the holes in the bellhousing where the bushing sits is somewhat wallowed out on the inner side from the shaft banging against it. I wonder if I built up that area with Kwik Steel or an epoxy mix and then fitted a new bushing I could solve that problem? Was there a post somewhere on using two bushings on each side instead of one? On a positive note the clutch disc and pressure plate are still in great shape. Any ideas or comments?
