Hi All,

I am one of the fortunate few who acquired of one of Jim Comstock's new cam chain tensioners. It just so happened I had my TS cover off awaiting a new cam chain in the mail so timing was perfect. (forgive the pun-i had to do it). Anyway, I think Jim is on vacation so I wanted to put these questions out to the forum so I can button up my bike.

1. Does anyone know the correct torque setting for the camshaft sprocket nut? It is not in the workshop manual nor in Haynes.
2. Anyone have thoughts on how much play there can be at the two ends of the intermediate gear spindle before the cases should be sleeved? (for example, mine is definitely loose where it is held by the outer TS cover but it is tight in the crank.) Should it spin within the gear? (mine does not.)

I have read all the posts about supporting the intermediate gear whilst tightening the cam nut and adjusting the cam chain, etc. so that is not the question. I am just curious if having slop in there is dangerous and how I can determine when I need to break her down for machining.

Thanks a lot,
Justin

It has to be tight in the crankcase but loose in the timing cover so the cover can be removed but still not loose too much as it needs supporting, the gear should spin on the shaft.
 
Re torque setting for the camshaft nut.

I cannot tell you the value for the standard camshaft but if you have a PW3 camshaft - made of cast iron whatever you do DO NOT use anything more than 20 ft/lb with some low release strenght loctite. ( Not the super strenght stuff)

Yes I managed to snap the end of mine off !!!!!!!!!!!!!!! :-(
 
Mick Hemmings says something along the lines of "a spot of Loctite and pull it down snug". I followed this advice. As for how much slop you can get away with on the intermediate shaft. I dunno. It would be tempting to use the green shaft retention Loctite and get the timing cover on to let it set, then pull the cover and assemble.

Another thought on the shaft. It could be set with JB Weld, the excess wiped away, then put the timing cover on and let it set up. Crude, but then again so am I.
