Frt crank oil seal pushed in
 

My k341 Kohler started puking oil out the frt crank seal all of a sudden while using. Took apart on the weekend and found that the crank seal has pushed into the block. Anyone seen this before? You would think the block would have a ridge on the block to stop this? Trying to figure out why this happened 😬

pretty common , the seal gets hard from age and comes loose in the block

just curious what are you calling the "front" of the engine?

Sorry pto side is what I’m referring to as frt

that's actually the"back".... the flywheel side is the "front even though they mount backwards in these machines. don't matter though as both seals can do the same thing. The one you are talking about is easier to change/ as long as you can get the PTO clutch off....
