Carsnz123 Posted September 30, 2014 Share Posted September 30, 2014 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!! Link to comment Share on other sites More sharing options...
Dandy Dave Posted September 30, 2014 Share Posted September 30, 2014 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!
