Ls3 Harmonic Balancer

[Jesse.15]

Any one any good with Ls Harmonic Balancers ?
I am replacing my harmonic balancer on my ls3.
I have pulled the old one off but I can’t press the new one on.
It’s a Auto so I can’t lock up the engine and I also can’t get it on enough to put the bolt on and pull it in.
Any suggestions ??

they can be a pain to get back on i actually bought a longer arp bolt just to get it started and then proper arp bolt to secure it after that, its best not to tap it on the crank isnt designed for length wise force, may have to find a bolt with washer just a little longer just to get it started then use proper bolt, if u can use a mini impact gun u shouldnt need to hold the crank from spinning or if so only to a minimum just set to proper torque to suit bolt
