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??

pretty much standard procedure to do a 3 step torque. you NEVER torque one bolt to max. go to the 90 ft. lbs on the third go around. 30,60,90 would be good setting. also these manuals are for mechanic's and you should already know that. they are not teachers.

Usually there's a prescribed order in which to torque the head bolts too.

Not a bad idea at all to gradually bring them up. 50-75-90, etc. Won't take but a few more minutes. Does it say to re torque them warm? I would. AC sent a service bulletin that we could over torque heads 10% and avoid doing it again warm. BUT, that was on an AC engine. So we went from torqueing the 301 engines at 150 to 165.

No, funny thing is not much is said about the cylinder head gasket installation, it gives the order of bolts to be torqued and the 82-91 lbs range and thats basically it. Thanks for the replies

I still can't get my head around this re-torquing issue. None of these engines were re-torqued when new and ran for thousands of hours without a problem.

BTW; I was taught to always do it in steps.
