Crank Torque settings

Hi
I have the following for my '42 Model U:
T&O flywheels
Jims crankpin
Jims sprocket shaft
Eastern pinion shaft

Any suggestions for torque settings to assemble this lot. S&S recommends the following for big-twin:
Big Twin
Sprocket 290-320
Pinion 140-170
Crankpin 180-210

Anyone used these with success?

Re: Crank Torque settings

The spec for the sprocket shaft given is for a larger taper. 150 is plenty for your output shafts on absolutely clean dry tapers.
