Replaced harmonic balancer

Replaced my harmonic balancer (vibration damper) today. Picked up a Dorman balancer from the parts store and a balancer puller kit, and a steering wheel puller.

Loosened the belts, removed the four bolts that hold the crank pulley on, crank bolt came off fairly easy (used two pulley bolts in the balancer, and pry bar to keep the crank from turning while I did this).

Used the puller to remove the old balancer, the rubber between inner and outer parts was squished and it had a wobble while idling.

Pulled the old oil seal, had a lot of trouble getting the new one in.

Used the steering wheel puller to install the new pulley, the large bolt fit nicely in the crankshaft for a few turns, then I just rotated the silver bracket so that it would push against the balancer, and I kept on doing this until it seated the balancer, I ended up adding a thrust washer in there from the other puller kit and I was able to turn the part by hand until it seated the balancer. I saw how to do that in this post and it worked really well... http://www.steelsoldiers.com/showthread.php?66270-Harmonic-Balancer&p=1405150&viewfull=1#post1405150

Cleaned up the old crank pulley and replaced it in the same orientation on the new balancer. Replaced belts and tightened. Runs smoother at idle now.

And there's some info in TM-9-2320-280-34 if you search "torsional damper" and go to 3-7

Check posts #88-91 (keep an eye on it!)

I replace the front crank oil seal whenever I replace the harmonic balancer. Just peace of mind.

I can't over stress sticking with AC Delco parts on the balancer...I change these all the time. The quality of the Dorman and other MFG's compared to the AC Delco is inferior, but this is a visual comparison....so I can't make any statements that one works better then the other. But an ounce of prevention is worth a pound of cure...

Which part number do you use for the A/C Delco balancer?

The balancer part number is embossed on the oem balancer....but you can just search flee bay for the balancer.
part number is 14022671

Don't forget to change the pulley bolted to the balancer at the same time. They are constructed the same way and often fail in the same time frame.
