Should be J tool J41665..

Use the J 41665 in order to install the balancer.
Assemble the threaded rod, nut, washer and installer. Insert the smaller end of the installer into the front of the balancer.
Use a wrench and hold the hex end of the threaded rod.
Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft.
Remove the tool and reverse the installation tool. Position the larger end of the installer against the front of the balancer.
Use a wrench and hold the hex end of the threaded rod.
Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft.
Remove the balancer installation tool.


Install the used crankshaft balancer bolt (139). Tighten
Tighten the crankshaft balancer bolt to 330 N·m (240 lb ft).

Remove the used crankshaft balancer bolt.

The nose of the crankshaft should be recessed 2.4-4.48 mm (0.094-0.176 in) into the balancer bore.


Measure for a correctly installed balancer. If the balancer is not installed to the proper dimensions, install the J 41665 and repeat the installation procedure.

Install the NEW crankshaft balancer bolt (139). Tighten
Tighten the crankshaft balancer bolt a first pass to 50 N·m (37 lb ft).
Tighten the crankshaft balancer bolt a second pass to 140 degrees using the J 45059 .
Remove the J 42386-A .

Picture a large socket, with a bolt running in the middle of it, with a nut on it. I wish I could show you a picture but my service sight doesnt allow linking unless you have the password

kent moore is the name of the company that makes the J tools. Check with a chevy dealer, since its the same process on the LS2.

Wait a second,...you have an LS1, hang on....

J41665 is still the same. Works on the LS1/6/2



...actually, any GM dealer should have it there. Or a GM training school,....or call SLP.

What is the purpose of this tool? Can you just use a longer crank bolt? Im really not understanding this tool.

I read the write up, why not just use a longer bolt? I paid 5.00 for a few of em from a local screw shop. Or is this where the white trash in me is comming out?

You can use a longer bolt, hell, i've used a hammer....i just don't want to tell him something that MIGHT ruin his pulley....You should use the original take off bolt to re-install the new pulley, then take it off, and install the new crankshaft bolt.

Well, I have to disagree with using the origional bolt. Just askin for trouble, a hammer yeeeee ha your nuts dude!! lol

on any gm vechicle with a third generation V8, you must run the pulley down useing the original bolt AFTER you have used the proper J tool to set the pulley in place.
