    Exclamation HELP! Hamonic Balancer Removal 05 Silverado 5.3L


    Support FSC and see no ads! - Click Here
    I have a 2005 Silverado 5.3L 4WD, and Im replacing the Front Crankshaft Seal, and the Harmonic Balancer. Before I pull the balancer off the crank, do I need to note the position of the balancer in reference on the crank?? The harmonic balancer does not have a keyway, so do I have to worry about where it at on the crank? The instructions at AutoZone says that there no need to mark the old balancer before removing? Is this correct?? If I get the new one on, and not in the correct spot, will it cause it to vibrate excessively?

    Thanks in Advance.

    I never marked mine on my 6.0 and had no problems, I did try and get it close by looking at the marks that were left on the balancer and crank though.

    What marks are you referring too? I dont see any marks, other that 2 drilled out holes on the new balancer. I dont know if the old balancer has them or not, I havent pulled it yet?

    By marks I mean the wear marks or "stains" so to speak from where the balancer sat on the crank installed. Once it is removed you will see what I mean, but it's an internally balanced engine so it won't matter where the balancer sits.

    The crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer prior to removal.






    4.

    Install the J 42386-A and bolts.







    Use one M10-1.5 x 120 mm and one M10-1.5 x 45 mm bolt for proper tool operation.


    Tighten
    Tighten the J 42386-A bolts to 50 Nm (37 lb ft).
