I have -according to the serial number on the instrument panel- a 1979 566. I say that with a little uncertainty because I bought this third hand as part of a lot of gravely stuff that represented "the leftovers" of someone's collection and there is some evidence of mixed parts/frankensteining among items in the lot.
With that grain of salt taken, the engine went kablooey this week and I need to replace either major parts of it or the motor altogether. In order to do either -I have been told- I need the Spec Number. So I don't accidentally swap out a crank with the wrong end on it or something. He says that the K301's that went on Gravelys had one of two Spec Numbers and I need to find out which one I have.
The problem is that the foil sticker on the cowling that is supposed to have the serial number and all this vital info has no printing left on it. It's just a square silver sticker. Do any of you know another way to tell what I've got? is there a feature I can see or a measurement I can take that will let me know?
Measure the crankshaft output end diameter and the length out of the case. They should be able to match it from there. Don't be surprised if you get a chuckle when you call and ask for Kohler motor info.. Kohler manufactures engines not motors.
