hi guy i just bought a Harmonic Balancer from jegs and the keyway on the crankshaft and the keyway on the balancer hub fits right but the hub is not at tdc it a 1:30 on a clock; is this ok

texastransam96

the balancer is a nuetral balance so i dont think it matters which way it is bolted on as long as it is bolted on... i know stock ones you just bolt on and torque down to the proper specifications... if thats a standard replacement it should be the same way i would imagine

help help

quickchek321

well i guess you right but why would jegs do that isn't it better if it was tdc

texastransam96

just to clarify this is an lt1 you are talking about correct? i just saw that this was posted in the v6 forums, so it may be a reason you havent gotten a lot of hits on the answer ....

edit.. i believe the keyway is cut in some of them to give them a little more added stability in not spinning on the crankshaft .. but there arent any timing marks to go by on the crankshaft to be able to tell if it is at TDC or not with the way the ignition is set up and the fact that it is a neutral balance

To clarify again, do you have a stock crank with the stock key? Because the stock hub is an interference fit, not a keyway fit.

quickchek321

no it is a lt1 i just register in this website i really don't know it to well sorry

quickchek321

well i mess up the old hub so a replace it with a new one and a new Harmonic balacner

texastransam96

isnt the jegs brand balancer only able to be used if you use there hub that they sell because of the way it bolts up ? i assumed he had the jegs hub from talking about the keyways and the fact it is aftermarket

quickchek321

is it ok that Harmonic Balancer a 1:30 everything is a tdc

quickchek321

yea you can only use there hub for there balancer

texastransam96

yeah it should be ok, you shouldnt have any problems whatsoever

quickchek321

are you postive because i put about 5 grand in this engine i don' want the crank to break on me from vibration

texastransam96

it is a nuetral balance.. you wont have it break.. you can put it on whatever way you feel like to be honest with you, as long as the engine is balance properly and for a nuetral balance harmonic balancer you will not have any problems with it.. i have put that balancer on a friends car before and it went on just fine and he hasnt had any problems to date ...
