JERRY H. - The manual steering gearbox in the green tractors is the same ROSS gearbox used in CC's. The guys on the green tractor forum even link to Richard C's repair FAQ to fix them. The only difference is the length of the steering shaft & tube.
The factory ball joints on CC's only lasted 10-15 yrs but the Heim joints I installed on my CC 72 in 1985 are still tight after 25 years so I can't really say HOW long they will last.
The driveshaft used in the green 2-cylinder l&g tractors seems to be as weak and as problematic as in CC, just MUCH more expensive. My Buddy has taken to buying rather complete parts tractors as opposed to buying the replacment drive shaft anymore.
MARLIN - I did NOT like the governor setup on the ONAN when I first saw the design in the service manuals I got from Binder Books after I got my 982. And having run it for ten years I can truely say I like it even LESS now.
From what I've read most people just throw all new parts at the problem, new complete camshaft, the governor is part of the cam drive gear. Which also requires installng a new crankshaft gear on the crank. Plus complete engine disassembly. Parts total around $400. Some also grind the valves & replace rings but my Onan has about 300 hours on a COMPLETE rebuild, which I think was new O/S pistons, rings, rods, intake manifold, gaskets & seals. It was rebuilt before I bought the 982 so not sure on the details. Not sure if it got bearings, they're plain bearing inserts like an automotive engine.
The problem is the governor is a plastic wheel with 8-10 fingers extending out from a hub which is pressed onto the hub of the cam drive gear. The plastic expands when the engine gets warm/hot and slips on the hub. It then acts like the engine has slowed down and increased the throttle opening to compensate which over-speeds the engine. I keep thinking there has to be some way to install some sort of positive drive key into the hub to drive that wheel. Someone suggested JB Weld already. I'm thinking Woodruff key but don't like the idea of square corners being stressed on a plastic hub.
I'd keep it, fix it up. It'll make you appreciate your 782D. And always remember what My DAD said, "I keep one of those %&#@ green things around to remind me to NEVER Buy another one!"
