No oil pressure, loose pump chain
Hi, Iím new to this forum. Iíve worked on cars and motorcycles but itís the first time I work on an ATV.
I have a 2001 Rubicon 500 with 4700kms and Iím having some issues which seem to be quite common with this model. Iíve read through a lot of threads on this forum and found most of the information I need. However Iím still puzzled with something.
- Engine is making a weird grinding thumping noise
- Wonít shift into any gear (as if I was always in neutral)
- No oil pressure at all RPMs
I removed the front crankcase cover and the chain was still on the sprocket, but it was so loose that I can easily slide it on and off.
Here are my questions, is it normal that the sprocket is loose (I can wiggle it on the shaft)?
I tried to unscrew the bolt holding the sprocket and it spins freely. Iím confused because the sprocket is not turning but the bolt is. Is it possible that the sprocket stripped on the shaft?
