Farmall M manifold torque and torque order

rankrank1 · Jun 28, 2013

Are there any recommended torque specs or recommended order to torque bolts/studs when installing the intake/exhaust manifold assembly on a Farmall M.

I have an IT manual but nothing is mentioned in it at all (Or I have not found the section yet...).

Thanks,

Proper torque depends on thread size. Use the chart at the link below for Grade 2 fasteners. (If memory serves the fasteners are 3/8 - 16 and should be final torqued to 20 ft-lb)

Start tightening in the middle and work alternately outward to the ends of the manifold. Recommend tightening to 50% of final torque first, then repeat the pattern to final torque. After the engine has run once and cooled, retighten to final torque if required.
