Well, it is in, awaiting some wiring details to run. What I found out..

The original block was from a John deere...I do not know if it would be different than a Cub block from a quiet line but there was one serious difference in this particular engine.

The output side of the engine had a stepped ring that probably was used to center an electric clutch in the Deere application. It got in the way of the starter -generator arm. A quick grind of the offending part cured that.

The output shaft is about 1/2 inch too long. I cannot install the clutch for the mower without cutting off some of the extra shaft.. Otherwise the clutch fingers do not go into the starter pulley basket. Also there is not enough room for the clutch button with the extra shaft in the way. RIght now I was getting the tractor ready for a pulling meet, so it isn't gonna get dealt with for now. Maybe I should have installed the entire crankshaft...

THe other side of the engine fits fine, I had a low boss head 14 I stole head studs from and barely had enough room to mount my gas tank bracket on them...the right studs would have been helpful on my high boss head. I also was amazed how much carbon was in this engine, but there was virtually no wear otherwise. Valve adjustment was almost dead on already, and the guides were pretty tight for the age of the motor. The ports are really ugly, I can see how a little work there would really help out a hi perf rebuild.

I did find a NAPA number for a metal backed crank seal on teh PTO end.. SKF 15041 seems to work well...the original was cocked and fell into the crankcase when I tried to straighten them..pulling the seal was fun.

Got to go look up the wiring diagram for a 122 now.. and get this thing running!
