Valve specs for Farmall A needed ....

Crazy Horse · Jul 7, 2012

First question ...... Can anyone give me some "cold" clearance settings for the intake and exhaust valves on a 1945 Farmall model A?

Second question ..... If the intake and exhaust cold settings are different, I assume the valve sequence from the front to the back of the cylinder head for the intake (I) and exhaust (X) valves is X I I X X I I X .... is that correct?

Thanks for the help.

1) I don't think I have ever seen cold clearance specs for an A. They won't change much from cold to hot. I suggest adding a couple thousanths to the hot spec. Then check and readjust hot.

2) You are correct.

Both intake and exhaust are the same setting. The book says 0.014 Hot and what I do is set them at 0.016 or 0.017. Learned many years ago a little rattle at the rocker arms is better then no noise in that area. Back when I had an old slant 6 in a dodge car I had I was told if they did not sound like a sewing machine then the valves where set to tight and would end up with burnt valves so you wanted a tick tick sound
