Flywheel castle nut orientation
 

Hey folks, I removed my '75 12hp flywheel because I have to repair my stator wiring harness due to mice. The castle nut was installed with "cuts" to the mating surface of the flywheel. Is this correct? Is replacing the seal a good idea since I'm there or is the quality and longevity of the stocker better than the replacement?

I am going to assume you are working on a Kohler K-301.

Not clear what you mean by "cuts". How about a picture of what you are talking about?

I'm assuming it's a K301, I haven't had the head off, I looks identical to my other motor.

I believe someone was in here before, one of the Phillips pan head screws was rounded out on the grass screen. I tried to grind a groove in it with my grinder. I had to weld a nut on it to finally get it off.

It was wrong side out.
solid side goes towards the flywheel.

Castellations do mot mate with anything, always away from the mating surface.

As for the seal I don't know. If you didn't disturb it leave it be, that's my thought.

Don't fix what ain't broke, a flywheel seal on that engine is not a big deal.

Ok, as I thought.

Thank you fellas

Can I bother you folks for the torque specs for this?
