The machine shop can't come up with the crank specs for the rods and mains in the pony. Does anyone know the specs?

Gpower is right on the spec's. I went through the same thing when I overhauled the pony on my R...I couldn't find any spec's on the crank in ANY John Deere book. Some good soul on this board sent me the spec's from an I&T manual and I gave them to the machine shop for the grind job. Pony runs great now and doesn't pump oil out the rear main.

The pony crank specs are: Main Journals, 1.499-1.500 with oil clearance of .001-.004 rod journals are, 1.373-1.374 oil clearance of .001-.003. That will get you back into factory specs. good luck,
Gpower

Smoker, Spoker.. GPowers R is the R that we have been dinking with.. (he's been doing most of the work, and the money spending.. )I been doing the supervising, U need to buy this, and find one of those.. hahaa... (Gpower will second that!!!) I knew he would chime in here with the specs.. (He think he sleeps with the manual.. No looking under my pillow.. could be a G book under there. haha..) But we have been thinking about a new toy... 80/820/830 (need a POS.. those are my favorite to start with.. ) Later guys.
