crankshaft position sensor installion

[Witness7]

I have a 1993 Ford Taurus Sho 3.2 and I am getting ready to install the crankshaft sensor as soon as the new crankshaft gear I bought gets to my home.

I seen on a site where it said you had to guage the sensor when you install it... here is what the page said

Set clearance between crankshaft position sensor assembly and one vane on crankshaft timing pulley and vane assembly using a 0.03 in. feeler
gauge. Tighten screws.

I am not sure how to go about doing this if you have to do this as far as where to gauge it at anyone have a ideal? and even a photo or diagram that is close up to where I can tell exactly where its suppose to be gauged?

Thank you

Go to step 30, that should help.

today i went to autozone to buy a feeler gauge to set the crankshaft sensor the above link says .....
You must gap a space between the metal vanes on the timing belt sprocket and the CPS to .03 inches, or .76 mm

the only gauge that I seen that might be the one I need to set the gap has on the blade .003 and then below it has .076 I hope this is the right one that I need cause I could not find one that said it like the link said it. I know its a really thin blade if that is it..... could someone please confirm this for me thank you in advance.

it is not .003" it is .030"

the sensor has a gap that the vane of the shutter wheel fits into. the gap needs to be approximately even between the top side and bottom side (but you cannot get to the bottom side to check it) which is around .030" or about the thickness of a matchbook cover. the sensor has a magnet on the bottom part, so it wants to clamp itself to the shutter wheel making the top gap too large. this is not acceptable, because when the shutter wheel turns it will destroy the new crank sensor. so, as you tighten up the screws on the sensor, make sure the gap is not too large or you will have a problem. I always use a matchbook cover or cereal box piece, because it is easy to fit in there and bend if you need to.

thanks, doing something like this is new to me even though i have worked on cars for years, never ran into a car that I needed to gap a crankshaft sensor, and not being great at math I had no ideal about that stuff.

do they even sale a feeler gauge that has .030" on it?

I did though the other day just use a feeler gauge that i thought would not be two thick nor to thin to equal it out... and I have drove the car around a mile and it seems to run good... and it starts up easy so maybe how I got it will work?

Probable if the magnet was touching it would already of quit running? one of my concerns was if it was not exact it would cause the car to miss?

thanks

no, if you set it to .020 or .040 it will not cause it to miss.

but, if you have it hitting, depending on how bad it hits, it may last only a mile or two, or it may last for a month, but eventually it will fail again.

ok thank you then it sounds like mainly all that is really important is making sure the magnet on the bottom of the crankshaft sensor is not touching the metal part that turns, I don't believe it is cause I turned it manually at the crankshaft a full turn watching as it turned and I did not hear anything nor feel anything catching while turning the crankshaft, but today I willl be sure its not touching before I finish it up... thank you
