I have recently rebuilt a 4 speed synchro box with new bearings and springs etc. Prior to dis-assembly it turned freely.
On disassembly I noticed that the layshaft had been fitted without any gasket under the flange on the rear of the shaft. Before reassembling I re-fitted the shaft and gear to check endfloat and found that there was none - in fact it needed a 10 thou paper gasket under the flange to allow the gear to turn freely. Where had the clearance gone?
I did gently heat the casing with a heat gun to help remove the bearings. Is it possible the casing has distorted with the heat?
