Can anyone help me out with the torque values of the prop bolts, and the crankcase through bolts for a C-85-F engine, with a metal prop and a flanged crankshaft ? I will be forever grateful for the info.

Re: Torque values
Get yourself an overhalu manual if you're messing with the through studs.
The torque values given above are for a wooden prop. Metal props are 360 inch lbs (or 300, depending on who you ask...)Comment

Also pay attention to the torque sequence to save yourself some heartaches later down the road.Terry Bowden, formerly TF # 351

Re: Torque values
Both Sens, and MCaulley have the torque values on their websites, based on what prop you have. TimN29787

Re: Torque values
Dry torque of 25-30 Ft. LBS. will install your propeller correctly. As long as it is a flange mount, not a tapered flange installation.
Hope this helps, thanks.
