The Onan B43M twin on my 8163 is tired and I want to re-power with a 22 HP HF670 while I overhaul the Onan. I am making my own adapter plate. I have a plate from a single cylinder (unknown which engine) 812. The Onan still runs, smokes & doesn't like to idle, I don't want to pull it until I'm ready to swap.
Is the Gravely transmission bolt spacing the same for all the 800/8000 tractors? :thanku:
