Rod bolts on Farmall Super A

Mtjohnso · May 7, 2019

Spec on torque for Rod bolts is 50-55. The nuts are the castle nuts and had a cotter pin in them. When. Torque to 50 there were many that did not align with the holes in the bolts. That is not surprising.
So I torqued to 55 thinking there may be enough movement to enable the alignment of slot on nut to the hole in bolt. That did not happen!
So I assume that I just keep turning until now have alignment even though I am exceeding the torque spec.
I know this is a Farmall question, but figured it is a generic issue.
So what have or would you do?

I would have put a drop of loc-tite on'em pitched the cotter pin and moved on with life...

I agree with Hobo, correct torque is more important than the cotter pin.

if you want to take the time to get them to line up you need to keep switching nuts and retorquing till they line up. or use locktite as said. or you can just get some stover nuts and forget the cotter pins.

"keep turning until now have alignment"

Yes, that's how it's done.

NEVER back off to reveal the cotter pin hole.

Many old shop manuals from "back in the day" detail this procedure.

I have at times if some are way off switched the nuts around and got them a lot closer.

I sometimes file a little off the bottom of the nut until they line up.
