Hi All,
I am about to undertake rebuilding a 99 crankshaft, and the next step is to centralise the crankshaft. However the inner race is stuck fast, probably corrosion. My questions are -
A) What is the correct method of inner race removal from the crankshaft.
B) My old Norton manual says the bearing should be a push fit, does this mean under normal hand pressure.
C) To centralise I will need shims, could any one advise on how many and what sizes I could buy as the initial selection to undertake the job as buying one at a time is impractical, so a few would be handy to achieve centralisation.
D) Also the camshaft is a bit pitted on two of the lobes do you think it is still useable.
Any help would be greatly appreciated.

If the main bearings will be like the original with roller on one side and ball on the other, you should not need shims.

Std mains on a 99 with classic use are pretty bullet proof , I rebuilt mine about 25 years ago and the orriginal bearings were perfect ,I changed them anyway and they are still fine. Std bearings are cheap.And properly locate the crank.

Hi Andy, I broke off the rollers and cage ,then drove wedges in behind followed by a gen Norton sprocket puller. In the Bad old days I would have put the cam back in ,but SH std cams are not valued much so should be cheap.With a proper oil bath feature the 99 cams have an easy time,especialy if you can increase the rocker feed supply as oil drains to the cams.Shafts can be eased with emery tape.
