It's been a while since my last post. My world-famous KT17 has a real good leak in the front that I believe is due to a worn out crankshaft seal. I have seen a suggestion that the seal is easily replaced by driving a drywall screw into the old seal, give it a yank, then clean up the area, apply appropriate seal and lube material, and voila! I will live happily ever after!
From what I see, the toughest part will be removing the almost 30-year old front pto clutch assembly.
The rear seal (Flywheel end) is dry as a bone.
I'm searching for comments, because the beast is lubricating my lawn at a rate of one pint per hour!
Otherwise, I really love this old machine. It's never let me down. Someday, if my meager retiree budget allows, I would like to repower with a Briggs Vanguard twin.
Thanks for reading this!! --- EdP

FYI, the job is done. The motor has an integral adaptor plate for the PTO clutch.
Four bolts hold the clutch in place.
When I pulled the adaptor plate, the badly worn seal almost fell out on it's own!
Never had to use the drywall screws!!
I cleaned everything up, pressed the new seal in place, installed the new gasket with some Permatex 2 and the leak has been plugged.
Thanks to everyone who looked at this and might have thought about sending on some advice.

Hi yard jockey. I'm sorry you havn'et been welcomed to GTTalk properly.
:welcometogttalk:

About your seal, I recently was reading another thread where a Kohler engine pushed out a seal. It turned out there was an issue with the breather assembly that was causing pressure build up in the crankcase. If your seal "fell out" I think you might want to check on your breather assembly as well. Just be sure to reassemble it correctly, as I think incorrect assembly caused the problem in the first place.

Thanks for the tip. This is the first real dry day in a while, and I'll be putting the tractor to the big test today.
It should behave very nicely, I am sure. --- Edp
