    Installing a Crank Pulley on LS1

    Hi

    The GM manual suggests that one uses a special tool to install a crank pulley onto an LS1. Unfortunately I do not have such a tool and as I am based in South Africa, obtaining one is not that easy. Hence the question:

    How do I go about intalling a crank pulley on a LS1 without the special tool?

    Any advise/suggestions appreciated

    A friend of mine had this problem the other day. he couldnt get the pulley back on because the crank bolt is too short... I don't know if this is the same problem you're having or not, but I have an ARP crank pulley, which is longer and would solve the problem.

    A ARP crank bolt will work to but the original balancer back on, just dont the washer at first and it will go right on.

    I made a tool just like the one pictured. Worked out pretty good. I'll dig up the specs on the thread stock because I forget them right off hand. I *think* it's an M16x2.0 pitch.

    Heat it in the oven for about 30 min. Get some gloves and work quick. Put some oil on end of crank. You may have to tap it lightly with a rubber mallet a few times. You'll be surprised how far you can push it on the crank. Pull it on with the old bolt. Crude, but it worked fine for me. Im sure some people on this site will freak out over this.

    Thanks for all the suggestions. With that information I am sure that I should be able to make the necessary tool to do the job.

    I tossed mine in the oven for a few minutes also. I didn't pull it on with the old bolt though. I spent $20 and made a tool to push it on instead. Removes any chance of damaging the crank threads.
