[QUOTE="Steve Morris, post: 133569, member: 3648"] Hi all. I have removed the timing chest on my Comet series C and am fitting a new ATD. On inspection i noticed that the half time pinion nut was loose with no lock washer... So, decided that i really needed to remove all the pinions and check as i also had an issue with the bike using oil/smoking. On inspection there were a couple of thrust washers missing/in the wrong place, so i have now removed all the pinions with the exception of the dynamo one, and the pins, and thoroughly check/cleaned all the above. I have done a dry fit (have ordered a new thrust washer kit) and with the correct shims/thrust washers in the correct places (as per P.Richardsons book) i have what i consider to be quite a lot of play in the pinions, id say on average 30-50thou on each one? I have made a video showing the play. Can anyone tell me if this is correct as i cannot seem to find in Pauls book OR KTB any reference to the correct movement/gaps? Many thanks, Steve.
