crankshaft senor keeps breaking


Recommended Posts

You could try enlarging the holes that the bolts go through so that is sits a little further out from the flywheel.  I tried to get the CPS closer to my flywheel that way and broke one, but it should work in reverse if it is already too close.  Also, the flywheel is partially open to the air (at least on my '88 Comanche), so I don't think the missing grommet would cause trouble as the chamber is not sealed.

Is the flywheel straight? It could be bent in one spot causing it to contact the sensor as it rotates around. How long do the sensors last? Die imidiately on startup or can you drive for a period of time?

I don't mean to dis on your wrenching skills but you did something wrong (as we all have).  It's not the CPS's problem, it's obviously being rubbed by the flywheel (or ?), until it gets so far eroded that it breaks.  What kind of sound does this make when it does work?   Does it make a different sound when you push in the clutch?

 

Omega rural's question, is the CPS pushed too far in?  To one side or the other?  It doesn't look like it can move in/out but I know it can move side to side.

I suspect something came apart possibly the friction disc or a finger came out of the pressure plate something came apart and is flinging around on the flywheel the grind portion of the sensor is too small for it to be the flywheel itself
