Kohler TH18-S. (gas) this triad has been declared a crap engine.. I haven't had any problems at all up till now. purrs like a kitten but crank case is pressurizing all of a sudden. ran fine when I took it out back after putting the fresh painted covers back on the tractor. went to move it yesterday & it just started blowing oil out every where. I repowered the tractor with this thing because it was given to me. got a lot of hours out of it so I cant complain But I'll need to find a bolt in replacement if I can't get it figured out. Need a shaft on both ends. Flywheel side drives the hydrostatic trans. Was looking at the 22Hp predator. looks like this guy did it.

I know a lot about a lot of things BUT I still have a lot to learn.
Life is what you make of it. So, why not make a working machine to make it easier.
