Rhino 3120 clutch help

I have a rhino 3120 and the clutch isn't working. I can start it in gear and drive fine but when I need to stop the clutch won't disengage. I have replaced the t/o bearing, pilot bearing, both discs and all 3 fingers. With no luck on fixing the problem. I have adjusted the clutch several times. Any ideas?

If it is under load, does it stop?
If it will start in gear does it start moving as soon as it starts?
Common issues:
A pilot bearing locking up causing the shaft to be driven even if the clutch is pushed in.
A worn spline on the input shaft can push the driven disk into the flywheel making it move.
The driven disk can be warped causing it to be transmitting power all the time.
The driven disk can be put in backwards causing the cushon spring assembly to smash into the the flywheels bolts.
Totally out of adjustment freeplay in the linkage. Jim

It starts moving as soon as it starts. I have adjusted the linkage several times with no change really.
Should the clutch fingers be touching the t/o bearing all the time or just when I press the clutch.

Welcome to YT
It's possible to install clutch disk backwards causing this problem or maybe disk is warped.

The release bearing should not "ride" against the fingers. Should be just a little free play before the bearing actually applies pressure to the fingers. If it is necessary to adjust it down against the fingers, something is wrong. The life of the release bearing will be drastically reduced, the clutch may slip under load.

You didn't mention replacing the pressure plate. That is usually where the problem is. When tightening the pressure plate bolts, they need to be evenly pulled down working an x pattern across the pp, otherwise the entire assembly can be warped.

As others said, it is possible to install the disc backward, but that results in the offset side of clutch hub rubbing against the flywheel bolts, which will cause the clutch to not release at all or make a terrible noise if it does release.

Other causes are the spline inside the disc is tight on the input shaft, or was damaged during the engine install. Also it is easy to bend the disc trying to get the engine splined back in, or damage the pilot bearing, especially if the engine is forced back in using the bolts. Hopefully you used an alignment tool. Trying to do a single disc without one is difficult, a dual disc is impossible!

Thanks for all the advice I'm going to tear it back down and check everything again.
