Farmall A Pulley

Don F. · Aug 17, 2008

On a Farmall A (C-113) motor, what holds the pulley tight on the crank shaft? I am putting mine back toghther after painting, but the pulley just had the 1/2 moon key, and it seems to me, just the fan and gen. belt keeps it in place. I checked with an Case-IH parts man and looked it up but couldn't find anything. Can any of you help?

It is an interference fit; you have to apply pressure to install and use a puller to remove.

...and lot"s of heat to remove.

Thanks for the response on my question, but it is off and it slide back on very easy. How do I tighten it up, to keep it in place, or will it stay with the fan belt holding it?

The pulley is supposed to be a press fit but since yours slides easy i would drill and tap two places one to hold at the key way and it should hold as some did have a set screw but most just were pressed on. Use a 3/8 set screw ALLEN HEAD.

Loctite has a product for tightening up parts that are supposed to be a press fit. I would check that option.

Just pushing it on and expecting the fan belt to hold it is a short path to needing to replace both the pulley and the crankshaft.
