Title: crank sensor and bracket removal
Post by: ENFORCER on March 19 2012, 04:04:56 PM
I need help getting these off the motor. The bracket appears broke. I have removed 1 13mm stud and 1 13mm bolt. I also loosened the pinch bolt, but it ain't coming off.
So is there another bolt that I am missing? Or is there some black magic involved?
Any help would be greatly appreciated!

Did you rotate the balancer assembly so a window lines up with the sensor?  If you feel along the metal ring on the back of the balancer plate, you can feel the cut outs or windows.  There is also a peg on the sensor bracket between the two bolts that the bracket slips onto  It may be stuck there.

Here's what I'm talking about.  There are slots in the "Blade" referred to below.  Just make sure it the plastic end of the sensor is line up with a slot.

Guess, I saw the peg, I was hoping it was not a broken bolt so that good. As to the window, no I did not rotate anything. Should I rotate until a strip of metal (window?)is inside the sensor area, or should I rotate until the metal strip is clear of it? Seems like if the metal was not there it would remove easier, but I have never removed one of these before.

I haven't messed with these either, until yesterday.   :D   Yeah, just make sure the plastic part on the sensor is in a window.  It should come out.  Same when installing too.

It can be a bit of a pain but that's the easiest way to do it. Good job Don. :rock:

Well I got the bracket out in pieces, and the sensor was also in a few different parts as well. Replaced both and cleaned the ring. Car is running great now. Thanks to all.

Glad you got it fixed....one of the simpler problems, but, one of the more common ones :)
