    Cam/pulley install question

    What up LS1's. This may be a stupid question BUT as long as I lined up the dots on the crank and cam gears/sprockets, does it matter that the crank is turning over some during the harmonic balancer install???? As long as the dots lined up prior to the pulley install, that's the important thing even if the crank is turned over a couple of times I'm thinking.........any clarification would be appreciated.......

    As long as you have the cam gear bolt down, lined up directly with your crank gear dot... It doesnt matter if the pulley turns. This is mine, should look like it. Again, if the cam gear is bolted down, lined up dot to dot, the crank pulley can turn all it wants on install.

    Oh, how nice to hear from you ORION!!! I knew you would come through for me.......Now to answer your Q.....No! The pulley sure is difficult to seat.....In fact it doesn't work to just get it on the crank ENOUGH to start threading the bolt.....It has to be pushed all the way onto the Crank fully in order to screw in the pulley bolt.....so I'm going to attempt to get this done today.(I rented a balancer installer from Auto Zone).... Additionally I read threads were many gus just heat up their pulley/balancer for 30 minutes and it slips right on.....Negative! This didn't work for me.........

    i feel your pain dude. i installed an underdrive fluid harmonic balancer and it was a total PITA to get on. i don't know the right way to install it, but i got out the dead knock mallet and went to town. lucky for me, i had just removed my sway bar the weekend prior. hopefully someone here can give us some advice as to proper installation so we all don't go around beating parts on our cars like i did.

    Right!!! Your on point there joedude....I mean there's so many little things one must know BEFORE taking on a project. I've certainly learned much over the past several weeks. Now, concerning the Balancer install, supposedly it is fairly straight forward with an install tool. So, now I'm going to start this challenge!lol I'll let everyone know how it went a couple hours from now. Thanks for the post......

    I bought a length of metric all thread and cut a piece off about 18" long then I used 3 bolts and a bunch of washers to push the pulley on. You use 2 of the nuts on the end so you can hold the all thread and the nuts act like a jam stop then start adding washers and push the pulley with the 3rd nut. I heated mine in the oven and it went right on with no issues. Good luck.

    This is by far the best way to do it. You do not risk stripping the crank threads with this method either like you do by using a pulley bolt......
