First course of business is to head over to Napa and pick up the two oil seals you will need for the flywheel and PTO end of the crankshaft. They're are about ½ the price of geniune Kohler parts.
The part numbers are:
Flywheel Seal: 7-04002
PTO Seal: 7-04003
I will caution you at this point that these numbers corresponded to the Kohler that came on my CC 129. I believe if you look on Napa's website for these number they will give you an ID and OD to verify that they will fit.
