davdeborg Posted March 1, 2013 Report Share Posted March 1, 2013 hi as your aware the bush wears in the gear linkage cover on the tys especially the ty175 there is some fixes but some are expensive ive tried something that works superbly and makes gear changeing a lot more responsive as the main oil seal is behind the cover the outer oil seal behind the lever is more of a dust seal as no oil should be behind the cover if it is then the inner seal has gone . i removed the outer seal and fitted a 12mm x 19mm x12mm bearing that i pressed into the casing where the external oil seal should be pressed it in with my vice and two pieces of wood so not to damage, the bearing fits tight and the shaft is nice and snug this allowing the gear change shaft to turn smoothly and also supports it taking out any excess play that has accured over the years. used it today and rode it hard lots gear changing and the differance is un discribable its like new . for £5.25 it is ideal might not be for everyone but it deffinatly works first class cheers 2 Quote Link to comment Share on other sites More sharing options...

ivor Posted June 16 Report Share Posted June 16 Hi just seen this post 11 years later. Finally dragged my Whitehawk TY175 out of hiding under a tarp in the barn and its in the workshop to bring it back to reliable, presentable working condition. Engine is sweet as i rebuilt this years ago before it was laid up, but the gear change is like stirring custard. Did the photo of the bearing fitting ever get posted, as i would be interested to see it before i seek out a new cover plate Quote Link to comment Share on other sites More sharing options...
