Forgot you had that one. I was referring to your current headache, I mean challenge, I mean "project". If you are like me what you refer to it as depends a lot on the latest issue you have found with it!

Finally, made progress! Valve stems ground (clearance), valves installed, heads on, valve covers on, intake installed. exhaust manifolds back on.

One small problem, I drove the flywheel side seal in too deep. By the service manual, .080" is the max depth to drive it in--I screwed up and got in close to .150". Looks like I have to order a seal, can't have any luck crossing it over. Anyone got an interchange # for 52-032-10 Kohler?

John,
I have a seal here and the # on it is 1177 and crosses over to this one.
Go here and see if it is the same size.

That one is too big, this one is around 1 3/4 OD. I'll get a magnifying glass or my son to see if they can make out the numbers on the old one. I can see the numbers, but can't attempt to read them.

Yes sir. Bout it, depends on how it's/they are working today.

Don't laugh, here is my setup for grinding the stem clearance. Held valve in V-block an used a mounted stone in a milling machine. To be honest it worked rather well and fairly precise. Probably needed a different wheel, but this one worked OK.

Not bad......

I've done with worse set ups and it ended fine.

My notes from a few years ago show SKF 13514 as a replacement for 52-032-10-S - front (flywheel side) crankshaft oil seal - KT-17/M-18.

Check the dimensions and see if they are correct.

Looks like a good set-up to me.
Did you spin the stone as fast as the spindle would go?

Yes, that is it! I spent a ridiculous amount of time trying to cross over the Kohler number, the number on the seal, and even looking by sizes--that really puzzled me. The one you listed, however, is not a "rubber covered" seal. Don't know if it makes a difference or not--maybe there is a difference in the sealing material? . There must be something to this as to why you can't find an interchangeable seal #. I can guarantee one thing, the seal I installed too deep was in an aftermarket set--no name and a different # on it than the original. Anyway, I have one coming from a Cadet Collector that needed to thin his parts supply.
I'm afraid to look (so I won't) but the seal you listed is probably on the shelf at 1/2 the parts stores in town.
