Worm wheel is good
No drive to worm wheel or crank as clutch just slips constantly, everything moves free and easy, cutter bar been overhauled, moves freely and smoothly.
clutch shows no sign of excessive wear – no ‘step’ worn into the gear.
It cut and drove well for ten minutes after engine conversion, had complete overhaul of everything except slip clutch, then the clutch started slipping, I adjusted it, it worked sporadically, then nothing, cleaned the clutch, still nothing.
Just thinking, tomorrow I’ll check the coupling for the drive pinion, if that has failed where it is located within the adapter plate . .
