Crankshaft Position Sensor Air Gap Clearence - ZR-1 Net Registry Forums

Jagdpanzer · 02-08-2013

Looking for information concerning the usual air gap clearence between crankshaft position sensor and the outside of 9 slot wheel machined in the crankshaft.

LGAFF · 02-08-2013

Are you saying that with the spacer its too far apart from the crank?

Lee
Just making sure what I have is with in spec when I get to that point.

LGAFF · 02-08-2013

need to check my eyes, I read that as the "unusual"....not usual as you posted...

LGAFF · 02-08-2013

I think as long as the spacer is in place you are good....I did not see anything in the service manual or video....pete might know for sure

I see Jerrys has different shim sizes, I will keep looking

Thanks Lee,
I installed the crank position sensor in the block tonight and the air gap measured 0.024" so I should be good to go.

I can't document, but I recall the early 1990 LT5 (first 500??) being the only ones that required a shim? Hopefully someone else can chime in with substantiated information.

966 had a shim
