Default End float play on new engine

Hi guys,

Building a new 2276 engine with all new parts. 82mm CB crank new standard bearings, new CB Performance Aluminium Race Crankcase etc etc.

But just checked the end float without shims and the play is 1.83mm?

I'm going to try tomorrow with a clear head as a little disappointed at the moment but if it's correct how would you solve the problem.

Lots of big shims? :-(

cheers
Dean

hat off to you sir. thank you.!!

torqued it up to 225 and the end float is now 0.80mm

I intend to torque it up to 350 with a gene berg washer and gland nut.

Would you recommend to torque it up to 350 and then measure the end float ?

cheers Dean

I do.

Flywheel and crank bolted together with just No1 bearing on.
Torqued with lube to whatever final desired torque value is
Then just measure clearance with feeler gauges. Minus desired end float wnd divide by 3. Job done

Glad it was as simple as that!
