We are looking for some info on how to finish the install of crankshaft sensor. We need info on how to set crankshaft sensor space with out the $300 tool that GM says is needed to do this. GM gives us part number j-37089-b for this tool. We are wondering if something else can be used in place of that tool?? If not how can we finish this install. We appear to have a different harmonic balancer than standard one and can't eye ball it. Ours has 1outer ring and 1 inner rins instead of one outer only. Any info that anyone has would be great. My bonne has been out of commission for nearly 6 weeks and believe me I miss it.

Thanks

That tool is a Crankshaft Balancer Puller it looks like this.


This ring is the crankshaft position sensor shield and its held with 3 fastners.

most parts stores now days rent tools give the gm number and they can cross reference it to what they have

I think he is refering to the actual alignment tool for the sensor. Unfortunatly I am not sure how you can align it properly. I was not the one that replaced mine.

yeah the alignement tool is what we need. We have called everywhere and no one has this tool for rent or sale. We live in a small town of about 12,000. The local delership can do it for $175. They estimated it will take about 2-3 minutes for them to align it. All of the work has been done we only need to align it.

Thanks again

That is pretty high to simply, pull the belt, possibly the harmonic balancer ( unbolts and pops off) then align it, then put it back together.


Do you konw any mechanics around there that may be able to help you out??

Sorry I only have a series 2 manual it seems the only thing required is a torque angle meter and the puller. Series one must be diff?

92 had an L27 right? If so,

You know where the sensor is, where the sensor sheild is, and where the harmonic is. put the harmonic on without the sheild and eyeball it, then whip the harmonic off, throw the sheild back on and say yee haw.

For everyone else, It looks like the L27/L67S1 are the exact same as the LN3/LG3, except they have added a sheild to protect the sensor.
