alternator threads stripped:( - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BrookelynnGreen · 04-18-2012, 11:55 PM

I was replacing my serpintine belt, loosened the alt bolt so I can move the alt from left to right, replaced serp belt and went to tightened alt up and my thereads were stripped

the alt is in good shape but I can't tighten it down because the threads are stripped. Any suggestions on how to save the alt besides making new threads?? I don't have a tap n dye to make new ones so I'm open to suggestions... Please. I don't wanna have to buy a new alt.

I have done this on more than one occasion.

Same, have done this many times, drill it out with a 5/16 bit and bolt her up.

ill third the nut and bolt but also use a lock washer too

Insidious you dont need 12 bungee cords ten good rubber bands will do the trick

Thread tap is easy to use on an already threaded hole, and you can pickup a complete tap and dye set set for 20 - 25$ at your local auto parts store. I would recommend this first as its a handy tool to have around.

But you can always drill it and nut/bolt it.

Tap to next larger bolt
Helicoil to repair whats there.
Bolt through.

I (what fourth?) the motion for a nut on the other side. I have that on my alternator right now. Works just fine and the alternator bracket already has a hole in the side for a wrench to fit through for the nut. I used a star locking washer as well for the extra security.

Ive tapped up to the next size bolt in the past.
