Crankshaft bolt size

travi80 · Aug 22, 2007

Does anyone know what the crank pulley bolt size is on a 1986 EFI 2.3L. During the rebuild on this engine it got lost amoung other important things. I have tried a couple different bolts with no luck. Any help on wether it's metric or SAE, thread pitch, and length would be really helpful.

Thanks

I would take one of the other bolts and go to a reputable parts house (NAPA etc) or maybe to Fastenal if you are near one.

I would if I could but the pulley only has the one bolt to hold it on. So without that bolt I can't even match it up. It was lost along with some other parts which I have finally recovered.

Oh, Sorry I didn't read far enough, thought it was a main bearing cap bolt.

Auto Zone lists this as a Harmonic Balancer Bolt Kit $5.99

Thanks for the tip I'll remember that for next time. I have actually found out that the bolt is an M14x1.25x50 just as an FYI to everyone out there. Thanks again for the tip.:thup:
