Crank position sensor spacer

Post by nismoit » Fri May 17, 2019 1:35 pm

Good afternoon, i just bought a crank position sensor (ERR3006 code) for my 4.6 gems - manual trasmission, but it came without the indispensable spacer.

Does anybody knows the thickness of this spacer, in pics seems like 2.5-3.0 mm...

Or, alternatively, someone knows how deep the magnetic tip of crank position sensor must go deep into reluctor wheel?

Air gap with most VR sensors is about 1mm. Not usually critical - say +/- 50%

Tnx Dave, in fact the magnetic pin is already perfectly centered between the two circles of metal plates (in gems engine, the 36-1 metal plates that trigger the engine are vertically fitted in two concentric circles in the flywheel). The spacer just regulate how much the magnetic pin of the sensor will go deep between those circles, i think that 4-5 mm (half of the total lenght of the magnetic pin) is enough to get a correct reading

Ah - thanks for the info. Never played with a flywheel mounted type.
