Here's all the manual says for the end float, (play)
Crankshaft end play is .002"-.026" on vertical crankshaft engines with a .015" gasket in place. If end play is less than .002" additional gaskets .005" , .009" may be added to obtain correct end play.
if end play is more than .026" with a .015" gasket in place, install thrust washer (PN 222951). install thrust washer on PTO end of crankshaft, install on the magneto side of crankshaft if there is a ball bearing in the PTO side only. then adjust end play as described in the previous paragraph ^^.

This video maybe more helpful than those few paragraphs.

Usually on the twins, you don't have to remove the exhaust pipes, they usually set down into the muffler mounted on the tractor.

Well that was the easiest motor I have ever pulled. Nothing broke and it came right apart. Nothing was rusted or stuck. 45 min and it was on the work bench. Another 15 min and it was a part and I just ordered the gaskets and seals.

It should be back together next week.

Thanks again for the help.

Oh by the way you could tell the gasket was leaking it had oil on both sides of it in several places.

Not on this one the muffler was bolted to the motor, once the bolts were removed it slid right off very easily. It's a great design.

OIl is cheap. Wally's mart has a gallon of 30w for like $9.75. Is it pouring out or just making a small mess?

Hey nice fix. Glad to hear she is back up slinging grass.

Yea, I was amazed at how simple it really was. But I'm sure it not being rusted at all helped a lot.

Thanks again
