    URGENT: Harmonic damper threads stripped

    I installed Steeda Underdrives on Tuesday. I followed the instructions with the exception of holding the torque converter by a bolt, since my factory TC lacks one. I resorted to using an impact wrench, but even that did not get the pulley on all the way (had another 1/16" to be in proper position).

    I pulled the pulley back of today and low and behold, the crank bolt is in awful condition (this was a brand new one).

    I do not know what to do now. I can't risk damaging these threads any more, yet I can't get it to a shop either. It's stuck in my garage.

    Can anybody offer solid advice on what to do next???
    Run a tap down the snout? If a tap is my best option, what size do I need?

    I'm getting yet another new bolt from the dealer today but I'm not doing anything with it until I get the crank situation resolved.

    Here are pictures:

    P.S. if anybody is in the North Royalton, OH area, I'll pay for your help and expertise!

    Did you use the installation bolt that came with the Steeda pulleys?

    Yep....
    STEEDA supplies a different length (shorter) crank bolt.
    They specifically instruct you to start installing the pulley with the longer OEM bolt, then remove the longer OEM bolt and then finish installing the pulley with the shorter STEEDA supplied bolt.
    Your longer OEM bolt is bottoming out in the crank snout.
    I'd clean up the threads by 'chasing' them with a tap, then clean the crank threads out with compressed air and then install the shorter Steeda bolt.

    CORRECTION:
    The 'install' bolt supplied by STEEDA is LONGER and the OEM bolt is SHORTER.

    My memory sucks...I did this install about 8-1/2 years ago!

    The Steeda bolt is the longer bolt. The OEM bolt is shorter. I used the Steeda bolt to start the installation and then switched to the OEM bolt once it was able to reach the threads.

    Does anybody know what size tap to buy?

    After looking at the pictures of your crank snout's threads....it does not look good.
    After you chase/clean up the threads with the tap, hand install the new, shorter, bolt and see how much wiggle there is.
    If the bolt feels really loose, the crank snout's threads may be too far gone to salvage....especially at the torque required for that bolt.
    You may be 'F'd and have to drill and tap the crank snout for a larger size bolt.

    That opens up a whole new can of worms.

    M12 x 1.5 according to Jegs/ARP

    http://www.jegs.com/i/ARP/070/156-25...rentProductId=

    They show a 1.8" underhead length.
    How does that compare to your two different bolts?

    Will this be a good tap kit? It has an M12x1.5.

    The length of the bolt measured from under the head to the tip of the bolt....basically the 'reach' of the bolt
    versus overall length which includes the additional length/thickness of the bolt's head.

    Both bolts are exactly the same at just over 1.8"

    I always equate Horrible Fright Tools as 'One and Done' use.
    That's pretty much what you are trying to accomplish here.
    You could probably pick up just that tap size for a bunch less money at a local hardware store.

    Something isn't right....one should be shorter than the other.

    Steeda's install bolt should be 60mm length = 2.36" = roughly 2-3/8"

    You are trying to save your crank (and teh disassembly of your motor and everythinbg that that entails if you don't). This is no place to cut corners.

    Go to Fastenal or Grainger and ask the clerk for assistance is selecting a better quality tap.

    According to the Fastenal website, no stores near me have any M12x1.5 taps.

    Even then...don't expect a miracle.

    Good luck, Rich. I think you're probably looking at some surgery at the least.
