I getting ready to re-install the rebuilt harmonic balancer.  The engine is in the car so I cant get a good visual alignment with the slot on the balancer and the key in the crankshaft.  Is there anything that I have to be aware of before I use the Casco install tool to slide the balancer on?  I'm hoping for a "one shot" attempt.  Thanks

Sometimes the key gets tilted and you have to tap it in the slot to get the balancer on.  It wouldn't hurt to use a little grease either.  Put some on the seal in the front cover.  Once you get it started, the Casco install tool should work fine.   Keep the crankshaft from turning.

Thanks Phil.

Charliebird, how did the rebuilders do on your balancer? You used Winslow, right? How is the quality as far as you can tell at this point? Thanks.

I talked to Winslow today, the harmonic balancer is on its way.  I have not seen it but I should be good.  I have a good vibe, but I'll advise you when it arrives.  They have been doing them for many years. 

The balancer arrived today, exactly 3 weeks from the time they received it to return to me.  That should be about right. From what I see it looks great.  They sandblasted and primed it. The donut is now in the correct position on the shaft.  "It wont rub anymore on the front mount".  I'm very happy with what I see.  Its primed so i'll paint it then reassemble the cooling system.  As far as centrifugal balance, I don't know, but Winslow told me they know how to bond the donut to the shaft, in the correct position.  Again, i'm happy with it. 

Thanks for the info. Sounds good!
