Hello everyone, I'm new to this forum, I have a uforce 800, and I'm hearing a strange noise and am wondering it it could be the clutch. Don't hear the noise while idling, only when moving. I have tracks on now and mainly use it for snow clearing. Just put two new rear wheel bearings and brake pads on. Noise was there before and after putting parts on. Hope someone can help.

Clutches usually make noise when there is no load on them such as just idling and become quiet when under load or moving. One thing that does make a lot of weird noise when moving is the heat shield over the exhaust the front pipe passes through on the Zs. The engine moves on the rubber mounts and the springs get against the tin and sounds like all hell is breaking loose. I once though I has a rod going out. A well places tire-iron adjusted that in short order. I mention this because as yours has tracks, it is putting more load on the drive train and engine mounts...and as such they will move more then normal. Might also check that the rubber is still in there and in good shape.
