1982 GS850L- Cluthc is Out!

If I'm not mistaken there was only one bad year on the 850s at least, and the gear had a golden colour as opposed to the black or grey.

Yep, these clutches don't "let go" like that.

I'd suspect the driven spline in the rear wheel is bad (most likely option), the driveshaft flange bolts have vanished, or the secondary drive on the back of the engine has gone blooey.

If I'm not mistaken there was only one bad year on the 850s at least, and the gear had a golden colour as opposed to the black or grey.

All, or at least most, 81 - 84 GS shafties had the soft driven splines. The only one in '84 was the GK.

The reason I say "most" is that Suzuki always used up its parts bins, so it's fairly common for early production examples to have prior year parts. It would not be shocking to find an example of an early production 1981 model wearing a black 1980 driven spline. The earlier spline units are also common replacements; my 1983 GS850G stripped its spline long ago at about 24,000 miles and is wearing a 1980 driven spline.

The "soft" part number was 64680-45112, superceded to 64680-45113 which was still in production use at least through 2019 on the 805cc M50 and C50 Boulevards (I think it's still in use on the 2020 models too).

The soft units are gold, the earlier units are black, and the later units are silver. It can be difficult to tell the difference between the gold and silver splines in photos without comparing the parts directly in person. A driven spline showing any significant wear should be replaced. Once wear starts, they will fail very quickly. You have to remove and clean the spline unit to get a good look at the teeth.

Looks like Brendan and bwringer nailed this one. I removed the back wheel and it looks like the splines on the wheel are stripped out. There's still some of the splines are left on the wheel, but they're only about 1/4 inch wide. The splines on the drive side look ok. I tried to paste a picture in this posting, but for some reason I couldn't get it to upload to the website. The splines have a gold finish to it (kinda looks like a cadmium plating). My next question is who or where is a place to get a good replacement for this?

I have a good one I keep as a spare. I don't need it.

Don't buy new. Black or silver ones pop up on e-bay regularly for about 40 bucks. They are fine.

Hey wymple- would you want to sell it? What part of Iowa do you live in?

[wymple]

As long as you don't need the wheel. I have the final drive unit itself, from my 81G, and it's good. I swapped in one from an 1150 on wrong info that it was geared taller. It was the same and I never switched back. I'm in SE Iowa, shipping shouldn't be too bad. Let's call it 60 bucks shipped.

Hey wymple, I sent you a PM to get contact info from you.
