John Deere 850 Aka yanmar 2500 rebuild

[winston1]

It does come up as an o-ring one time but mostly as a bolt. That part number is out of the John Deere 850 parts manual. The John Deere 850 and Yanmar 2500 pretty much share the same engine. No warranty on my part that it is correct is my feeling is is correct.

No part number for it showing anywhere looking at couple Dia. and parts. Call Fredricks they should have it no doubt. They refurbish that model and just might have a real good idea.?

A stud is a simple part for a competent machinist if you can't find one

Got everything back together almost and one of the studs that hold the rocker arm assembly on snapped. I’ve tried everywhere including John Deere and no one has one, does anyone have any ideas on a different one I can use or something.

It you got the part in hand, take the stud to Fastenal in a popular town. I was able to find replacements from them for my rear axle.
