I am in desperate need of 3 rocker arm studs and nuts for the Yanmar 3T80UJ engine in my JD 750 tractor. Any ideas or does anyone have a old head with the studs in it? JD part number is CH15433 it's no longer available from John Deere.
I have a JD750 and the previous own has rewired the electrical system and added a solenoid on the firewall. Anyone have any idea why they would have done this?
