Can someone tell me the torque specs for the rods,cyl head and exhaust manifold on a 37 A? Thanks, Mark.

Some one will know and pipe in. You can always Google the generic bolt size chart(s). HTH

Mark, odds are the rods are still babbitt rods and will need shimmed. We worked on these tractors for years and never even owned a torque wrench. We just got them "tight". After years of practice you pretty well know when the torque wrench will click anyway. I believe the cylinder head nut torque on untreated head studs is 125 ft./lbs. and 150 ft./lbs. on treated (black) studs. On most A and 60 tractors I put some #3 Permatex on the outside vertical rails ONLY of the head gasket and tighten uniformly in 10 ft./lb. increments until tight. This has worked for me for many years. Mike
