That pulley is part of the water pump. The water pump has failed and needs replaced.
Keep the a/c OFF!!!! with it off does the pulley on the a/c compressor seem to be locking up or wobbling when the engine is running with the A?C OFF????? if the belt looks smoooth then you may be ok until you replace the a/c clutch?
get a smaller pulley for the engine. as far as clutch I'm not sure
Your power steering units pulley has worn or broken bearings. This can harm your vehicle, suggest you have it replaced.
Bent shaft, replace PS pump
No, a pulley will not keep a car from starting. A pulley is part of a wheel, and it is held on by an axle. There are many other components that go into this, but none of them have to do with the engine working.
Tighten the center bolt on the pulley and if it's tight and still wobbles then replace the pulley.
Try the alternator pulley wheel - it has a clutch. Mine just sheared of completely (the clutch had disintergrated)
The center of the clutch is attached directly to the engine crankshaft, when the engine rotates faster the centrifical force spins weighted arms that are attached to the center of the clutch to the outside casing of the clutch forcing it to spin when the arms touch it. The outside casing acts as a pulley for a chain or a belt, separated from the center of the clutch by bearings so that it does not spin until the arms touch it.
its built into your water pump.
put the smallest pulley you can get on the tranny, and the largest on the engine. do not mess with engine rpm as the piston could blow throw the head or the engine could over heat and become junk. You may have to make clutch adjustments or make your own clutch. You wont want to get the smallest or largest pulley because your tractor might not have enofe power to stay running and driving.
The electric PTO Clutch is Electromagnetic. There is a stator which creates a magnetic field when voltage is applied and this causes the free spun pulley to lock into place with the crankshaft of the engine. When voltage is release, spring pressure forces the pulley away from the stator. This is over simplified but that is about it.
The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.
