Does anyone have a manual listing the torque specs for the rod bolts, mains, head, and manifolds etc for the '46 Farmall H model?
NOT an HV model

Randolph, Be careful, it depends on whether you have the original flat head pistons or if they have been up graded to the fire-crater or stepped head pistons and the rebuild kit. I have seen a higher torque spec's on the fire-crater pistons along with complete bearing kit. When I rebuilt my '46 H with fire-crater pistons this spring I put 50 ftlbs on piston rod end caps and 85 ftlbs on the main bearing caps. The Case/IH manufacturer instructions indicated 45-55 ftlbs on the piston rod caps and 80-90 ftlbs on the main bearing caps. Of course all of the above is not the same as spec's in the original "serviceman's guide" for the H.
