K301 hot, smoking, but there is good news!

Hello everyone;

I recently bought a "barn find' C-120. The PO said that it was worn-out and needed a rebuild. I got it home and pulled the head and found the head gasket blown. I also noticed the exhaust valve was badly burnt. So off came the motor.

I pulled it apart last night and found the piston and rings fine along with a nice bore...only out .001 on dia., and hardly tapered.

I also noticed that the balance gears were extremely loose. I was kinda happy that I noticed. So, come Monday, a new valve and gear bearings as well as new rings are coming from Kohler as well as the necessary gaskets.

Everything else looks great, and yes, I am leaving the balance gears in. Will keep you'all posted on the firing of the motor sometime on Tuesday.

Is a great lookin' tractor with low hours. Hope to find-out how to post pics soon, 'cause I know everybody likes photos.

Tom,are you going to tighten them balance gears up,Rick

Tom, I'm no engine man - far from it, but I'd be leery as h*ll of those loose balance gears....I think I've read here a number of times that the best idea is simply to pull them and turn them into scrap before they turn your motor into a grenade. Experts?

Hi Guys and thanks for the concern over the balance gears.

I ordered new pins, bearings and I have a good asst. of shims. They will be installed to tolorences. Besides, it is the way Kohler intended, and Iam no engineer by any means.

I had my brother, the machinest, clean-up the intake valve in the lathe and I lapped it in this morning. The exhaust valve...which was badly burnt came-in this morning, I need to lap it in as well. With any luck at all, I should have it back together tomorrow.

Get her going. Started on the third revolution. Adjusted the carb a bit and then went and cut grass today for about 2 hours. Runs great.

Thanks to all who helped me on this project.

Thanks Bob for your help in getting the fuel system going. Maybe I can e-mail you some pictures to post. I still have not figured the photo thing yet.

Because I know that everyone likes pictures!!
