torque specs on B Farmall

Deryl Sewell · Mar 18, 2011

Does anyone have the torque specs for the head and intake manifold on a B?

I don't know what the specs are for the manifold, but the head calls for 80 ft/lbs with modern head gaskets. Start with the center bolts and work out to the ends.

Don't forget to re-torque again after you run it and warm it up a little.

80 ft-lbs on the head. Take it in stages. Your pattern sould start in the middle and work clockwise (or counter-clockwise, no matter as long as you proceed in which ever direction you choose) so that your bringing the center down first and working your way outward, alternating ends. Take them down to 45 or 50 on the first round, then down to 65 or 70 on the second pass and finall down to 80. Run engine until warm and let cool. I always warm up and cool a second time, before going back over and retorquing the last time, again to 80. Because the rocker has to be removed, this will mean setting your valves twice.

Manifold nuts, I've never seen a spec, so it's common sense snug with one extra snug. Make sure you have the washers under the nuts where the flanges are split to allow for expansion and contraction.

Thanks guys for the torque info. I'm putting her back together this week so fingers crossed.

Don't forget, there are charts all over the internet for standard torques for your size and grade of bolt. I torque anything I can fit the torque wrench on.
