Torque on C head

Tue Oct 10, 2006 3:17 pm

I need to know how many ft lbs to tighten the head down on the C, i can't seem to find int in my manual, it just says "snug"

The head nuts on my '45 B Farmall are torqued evenly to 65 ft. lbs., per the service manual. I started at 45 ft. lbs. and worked across the head three times, increasing the torque 10 ft. lbs. each time.

The manual says to start the sequence at the center of the head and work back and forth accross the head toward each end.

Here is the sequence I used:

8 4 1 5 9
7 3 2 6

Thanks Bud, i will do this tomorrow, today i just tightened them up a little bit, since it's the "domed" or whatnot, should i tighten them up a little bit more?

also, is this just somthing from teh factory? or is this bad? Image on all of my pistons, it seems to be identical, just wondering...

also, ifn i put my finger in my oil pan, there is some type of metal that flaps up, but doesn't move, i would take the oil pan off, but it won't come off :shock:

I installed flat-top pistons in my B, but I think those valve cut-outs are there on keep the pistons from hitting the valves in the TDC position.

That metal thing that flaps up and doesn't move is the oil pick-up on the oil pump. It moves up and down on purpose. Can you guess why :?:

Thanks, that's what i was thinking... too bad i can't take them out and balance them :lol: 8) :P

hmmm, no, i can't say i know, but i will take a guess, somthing to do with sludge :?:

The oil pick is meant to float with the fluctuating oil level in the pan on uneven surfaces....insures a constant pick-up of oil on hills, etc. 8)

Go with the 65 ft/lbs, and it's a good idea to retorque after about 50 hours of operation, though bringing the engine to operating temp and letting it cool a couple of times will do in a pinch.
