1955 Dodge truck camshaft sprocket bolt tension

Recommended Posts

I'm rebuilding a 1955 dodge truck 230 cui Flathead 6 for my 1925 Chrysler project and I cant find any info on how tight to make the bolts on the camshaft sprocket. I have a workshop manual but it only mentions the tension for the V8 camshaft which is 35 ft.lb. when i tightened the bolts to this I broke the first one.

what should the tension of the camshaft sprocket bolts be? HELP!!

Till just before they break. ;) 32 foot pounds is a common torque for a common grade 5- 3/8ths bolt. Not sure what size bolts are in it? But you go with the torque that fits the bill. A grade 8 bolt will take more torque than a grade 5 or 3. Dandy Dave!
