JIM P. - If you "go by the book", I've seen where people have spent over $500 in just parts to fix the Onan governor issue. The only repair part available today is the complete cam gear w/plastic finger wheel installed, which to install according to the book requires replacing the crankshaft driving gear, plus all the gaskets/seals required to even get to the thing. Yes, I'm sure many people replace the cam gear without replacing the crankshaft gear, but who's saying the new finger wheel on the new cam gear won't start slipping? I have heard that the new finger wheel has one long finger that engages the notch in the outer rim of the cam gear. Poor design in any case expecting a molded plastic part to drive reliably with a press fit on a cast iron gear when plastic expands five times the amount of the cast iron. The govenor issue will be "addressed" when somethng else in the frt of the engine needs attention. I'm the only one that runs the tractor and I know to keep RPM's in check. I've run the tractor for 10+ yrs this way.
If I was to pull my G48G again to fix the governor, guy on another forum used a piece of plastic bar stock to make a driving lug for the finger wheel that extends into the recess of the outer rim the gear teeth are hobbed into. Positive drive until the finger wheel breaks.
My finger wheel must not be too loose, governor works O-K when I first start the tractor, loosens after 1/2 hour of mowing most times and lets the engine run faster when there's no load from the mower deck. Like I said in the other post, when it's cold, the governor works fine.
BILL J. - Year ago when I refurbished the 70, I completely rebuilt the steering gearbox. It had been replaced back around 1970, and had some work done to it sometime by Dad since then. I had a Dave Kirk Nice #605 bearing Super-Steer kit left over from the 72 8 yrs ago, that kit wouldn't work on the brand new 1990's vintage complete new steering gearbox I installed in the 72. But with a complete cleaning, reassembling, greasing, and using a good used frt wheel bearing on the steering column and Dave's kit, that 70 steers like it has power steering. MUCH easier than the 72 with the same frt tires, similar frt tractor weight, and a brand new OEM steering box.
STEVE B. - I was pressed for time yesterday, I didn't have a chance to check the newer MTD tractors. I "think" the B48G has a 1-7/16" bore on the PTO clutch, but I "think" the 1-1/8" bore clutch is more common. I'd really like to have a Duetz 2-cyl air-cooled diesel in the tractor, they're out there somewhere, but failing that, I'd prefer the Kohler Mag 20, but the B&S Vanguard 23 HP is a good engine. Long as I can still buy some parts for the Onan, I can keep it running.
HARRY - I think you're looking at Steve B's Q/L vs '82 series sales info with "Quiet-Line Colored Glasses" on.
Only two models of CC's I will NEVER own; '61/'63 CC because of the belt drive from the engine to the clutch, oil bath air cleaner, and the chance for the fabricated steel frame cracking where it bolts to the cast rearend; And any Quiet-line mostly because of the iso-mounts.
About 30 yrs ago I was shopping for parts for the K241 at an off-color dealership. Their brand of tractors also used the KT-17 series I engine. The town's parks dept. had several of the off-color" version of the 782 CC, even with HS & college kids running the tractors they saw 2000-2400 hours between rebuilds with no failures. Like Steve said, keep them level and they last.
