The crankshaft is splined. The front pulley is timed to the crankshaft. When it was put on last, the mechanic clearly did not know this and did not install it correctly.

Solved! Seems that the previous owner had removed the crank pulley and installed in out of time. Corrected that and it runs nice and smooth.

Factory setting. Thinkk it's about 1000rpm

Idle rpm is set correctly. I have several other of these machines and this is the only one that I've had this issue with.

New to me rtv x1100c. Starts great. Runs great down the road. Problem is that the engine shakes quite a bit at idle up to about 1/2 rpm. At full throttle it's not noticable. I swapped out the injectors and injection pump delivery valves with another engine and it made no difference. Any...

I drained the oil to check the rubber hoses going up to the suction filter. Unfortunately they are fine. Not sure where to look next. Don't want the pull the tranny apart to check the charge pump unless I'm sure that's where the problem lies.

The charge relief valve is just a simple little spring. It's not broken. Just to be sure I replaced it with another one I had and no change. Oil is good and filters are new

Plugged a pressure gauge into the charge pressure port. I'm only getting 20psi. Checked the charge relief spring like the manual says. Looks fine. Now what?

New to me rtv 900. When I got it it would barely move under full throttle. Figured it wes the wear plates on the hst motors. Replaced them, now I get no movement at all. Even tried switching another complete valve plate. Hst motors were all in good shape. Changed the trans filters as well...

I swapped it with another one I had

Near as I can tell it was bad seals in the valve body where the bottom shaft runs throught. Oil was leaking past the seals and draining out the small drain hole in the bottom of the valve body.

Older RTV 1100 that I'm working on. The alternator is charging but the charge light on the dash stays on. Any ideas?

Got it fixed. Took the hst apart to find the front motor pistons badly worn. The face of them were pounded out flat not convex like they are supposed to be.

Changed oil and filters - no change Pulled out forward and reverse relief valves - no issues seen Pulled charge pump check valve - no issues apparent. Any other ideas?

New to me RTV 1100 Will drive forward and reverse up until maybe 20% throttle pedat movement. Anything beyond that and it stops moving like the hst pressure dumps. If I come back to idle it will move again. Jacked up the back wheels and disconnected the servo rod so that I could run the...
