My service manual came today for the Allis Chalmers 5040 tractor, I have the cylinder head off of it so i can put a new head gasket on it. The manual shows me the correct order to torque the bolts, and they say to do them 82-91 ft-lbs. It does not tell me anything about if i should gradually increase the torque and how many times they need to be torqued
For instance my 555 ford backhoe had the same repair last year and the book said to do 90 ft lbs, then 100, and the last torque was 110. I'm not sure if the AC should be done in steps gradually increasing the torque to get to 91 lbs. or do you torque it one time between 82-91??
