Going over our NAA to get it shape for next year. What is the proper way to redo the torque on the head bolts ?
Should I loosen them first then retorque or just apply the correct torque to the bolts folloeing the tightening pattern ?
I do not think they have been retorqued for years and assume they might be frozen a bit form sitting in place for so long.
Thank you for any help you can give me.

If it ain't broke, don't fix it !!! Torque specs are for clean, well oiled threads, you have neither. Leave it alone if you aren't replacing the head gasket.

I agree with welding man, don't mess with them now. A re-torque is only meant to be done soon after replacing a head gasket.

Thank you for your help. I will leave them alone as both of you suggest. There is no apparent failures.
Thank You !

Are you talking about doing a winterizing job? I concur with the gentlemen - unless you have a rebuild project going on, forget torquing head bolts. Most guys don't know how to properly apply torque anyway. Do you have your Essential Manuals? Best investment you can make for your tractor ifN ya wanna be a FORD TRACTOR owner. I&T FO-19 will detail R&R'g the engine with torque specs. Sequence usually works from the inside outwards, BUT READ THE MANUALS beefier doing any work. CLYMER/I&T FO-19 Manual and the Ford Service Technician Manual for the NAA would be a good start, but as required reading, not to try and torque head bolts. You could end up busting a bolt if you dont know what you are doing and then what?
