Yeah, but it isn't something you see happen very often. It's honestly kind of hard to let that happen to the pulley of the crankshaft. You had to have something going on in the engine before that happened. But I do know how to fix the warping in a crankshaft pulley from happening again, but it wouldn't be cheap.
no
The crankshaft pulley is the large pulley on the lower passenger side of the engine.
The most logical reason for the key or tip as you call it breaking off is probably a result of improper torque on the crankshaft pulley or the crankshaft pulley is out of balance.To prevent this I would highly suggest buying a new crankshaft pulley that will be balanced.To explain what happens over time the strain of adjusting the belts from the alternator and power steering and air condition pull the crankshaft pulley with varied tension and can cause the crank pulley to warp to a degree causing it to be unbalanced.While this may seem a bit strange the metal will be affected by this due to age,temperature,torque from the belts tensions pulley left and right.Best bet buy a new crankshaft pulley (note just look at the pulley while idling and see if is wobbling) this will tell you the pulley is warped or out of balance.Plain and simple!
the crankshaft sensor is located behind the crank pulley. the bottom pulley
The crankshaft position sensor is located at the lower left hand side of the crankshaft pulley. The crankshaft pulley is the large pulley located in the center lower portion of the front of the engine.
The crankshaft pulley has broken causing the outer ring to slide forward into the fan assy. replace your crankshaft pulley and all will be well
The crankshaft pulley unbolts from the harmonic balancer. The harmonic balancer can be removed from the crankshaft with a 3 bolt puller.
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.
Power steering belt to crankshaft pulley. Alternator belt to water pump pulley and to crankshaft. A/C compressor belt to power steering pump and to crankshaft pulley. Smog/Air pump belt to water pump pulley. This is for a truck that had a 2 grove power steering pulley, a 2 grove water pump pulley and a 3 grove crankshaft pulley................
It is located behind the crankshaft pulley and requires the pulley to be removed to change it out.
It is on the front of the engine on the end of the crankshaft.
Looking at the bottom side of the front of the engine at the crankshaft pulley, the CKP is at the 10 O'Clock position of the crankshaft pulley
