Re: Jerky Transmission & chewed out rubber doughnut drive couplers
Hi Jimmy,
Sounds like the drive from the gearbox and the axle input are out of alignment. Have you had this checked? I don't have first-hand experience with the reverse gearbox fitted in OHV engine but that's what I would start looking at. Maybe you can re shim the engine to get a better angle for the drive shaft? Or you may need to change the length of the driveshaft itself. I have owned my Chang side valve for 20 years and never changed the coupling yet!
