750 crank question

Hi guys,

I've got a crank question. I've managed to get my hands on another one recently, the only problem is it's already been dis-assembled, don't seem to be any marks as to which should be the drive/timing side on the flywheel. Any way of telling easily? I can only guess that if I bolted it together the wrong way round it'd try to shake itself to pieces?

Cheers,

Steve

Hi Steve,

I wish i could help you, but I will be interested if anyone can tell you a way to identify which way around the flywheel section is mounted, I marked mine before pulling apart to be sure, cause I think they line up both ways.

Bolt it up without using undue force (if thats needed it will probably fit better the other way round) and put it on a balance rig - straight edges or forked rollers. If it is the wrong way round, the big-ends will not be stopping at perfect vertical.

Hi WEAL Norton,

Big thanks for that. If they're out of vertical, is it quite noticeable, or will I have to use some kind of measuring device?

Cheers,

Steve

p.s Richard...Now we both know!
