Winfred or Bill - question regarding timing/crank wheel

[Jon K]

I am using the stock 60 - 2 crank wheel on the M50 for my MegaSquirt standalone project. I don't have a wrench big enough or a socket short enough to turn the engine to TDC (plus my TDC mark is all gunked) and was wondering if you guys could help me out.

I am trying to determine what tooth the Crank Position Sensor is over while the engine is at TDC... I guess the count starts from the missing teeth? I unfortunately can't get my car to TDC right now and my M50 on the engine stand has no crank position sensor on it

Could someone maybe put their M50 at TDC and tell me which tooth the crank position sensor is on and if its on the leading edge, falling edge, or dead center of the tooth? Thanks.

No rush - I'll shoot you a PM or something - are the teeth on the wheel pointed or squared? I cannot remember.

Also, have any good Crank Position Sensors laying around?

square and probably, id go new on my own car as they can crap out after handling

theres 5 teeth to the left of the oIt to the gap, the sensor is between the 2nd and 3rd but mostly over the 2nd starting at the oIt

**** thanks winfred, i totally forgot to ask you about it - sweet, you pulled thru. I am trying to make out your explaination. The forum messed up your ASCII drawing - hm. MS Paint? thanks so much. Can you check my other thread about M50 rebuild - had some questions in there. Thanks again.

different screen resolution? 1024x768 looked good at work and here at home, you just want one of my wonderful shitty hand drawings run through the scanner, i guess i could of numbered them the other way, it's gap 5 4 3 2 1oIt

See picture.


There is a mark on the timing cover. The 0 deg TDC mark on the flex damper lines up with the mark on the timing cover at No. 1 piston TDC.

Hope this picture is better.
