Here are the broken parts on a 15 kohler command pro
with LESS THAN 100HRS alot less.
Note: the main bearings and cam bearings are intact!
Only the rod bearing seems to be at fault

Tideman,
I thought that also, but notice the gear they discolor when overheated. And this one is fine

What about all of the other bearings...farther in the system....without a scratch.

This is the only other clue.
The gears and cover on the left are this motor, and the one on the right is from a 2000hr+ motor

No...just clean oil
My reason for posting is Kohler wants to deny warranty
