[QUOTE="donrapide, post: 11123, member: 120"] With ref to Timetraveller's query, the needle roller came in three parts. The circlip, made from stainless steel wire, is just to prevent the bearing falling out when assembling or walking inwards when there is no pressure on it. There is clearance between the circlip and the rotating outer bearing track so that when clutch is lifted the outer track is free to rotate. The attachment on the pushrod is made that way so that the coned part ensures entry when assembling. The second bit is to centralise the push rod into the bearing and the flange bit is to bear onto the outer bearing track. The flange bit is not hardened, made from stainless, originally put together with Loctite Retainer, which did not last long. So now is silver soldered on. There is no sign of any wear on either the outer bearing track or the attachment. The main reason for fitting this was to try and get even and level lift, thus hopefully giving no drag. The next trial, maybe next winter, is to fit a clutch brake to give soundless 1st gear engagement and a sweeter gear change. There is always something to play with these machines! Hope explanation is fairly clear, if not, get in touch. [/QUOTE]
