Engine specs for a D

Patsdeere · May 5, 2016

Working on an unstyled D and have the head in the machine shop. The shop was asking if I had specs/tolerances for valves, guides, spring strength, etc. Is there someplace where I might find that info?

Thanks.

You need the Service Manual for tractors and engines #SM=2000. Has all the valve,seat,guide and spring measurements. Ron Mn

Great. I figured they had to be somewhere, and I know I had them for a case, but couldn't remember ever seeing them for a Deere.

Thank you!

I thought I may have had that manual, but can't put my finger on it.
