Tips for R/R of harmonic dampener???

Hello Larry,
When pulling against crank use brass or something softer than the metal to protect end of the crank and threads.
you will want to measure the inside diameter of your new balance & then the crank snout .0017" to .002" press fit, I use permatex non hardening on the key and snout to seal for leaks when installing, replace the seal and use engine oil were the seal and crank meet when sliding on during assembly, I say this loosely as you will probably have to heat up the assembly to get it on due to the pressfit.
I've sent you the instruction sheet to mine for a better discription, good luck!

Larry, Whats wrong with the old one? If its just the markings, thats an easy fix. A little white-out, And when its dry a little light sanding over the lines and your done. When your using the puller rotate it a little it it seems tight or slow comimg off. Another tip, don't hit the new one on! Not with anything. Use the the bolt to draw it in.

Terry,

Study that photo. See the gold tint metal on the left? That is the Aviad oil pan. See how the rear of the dampener outer ring is now in contact with the pan?

See the 1/2" of semi-shiny metal to the right of the outer ring? The outer ring is supposed to be flush with the front edge of that newly exposed metal.

Classic separation of the inner / outer pieces with full rearward movement of the outer ring.

Sigh...but better found now than in the parking lot of The Orleans.

I've changed the HB on my three cars in the last year. The standard 3 bolt puller works fine, you can actually get three lined up. I used anti seize and a HB installer which is cheap and makes the job easy and damage free. Hopefully you ordered the spacer adapter if your HB needs one or the pullies will not line up. Most aftermarket ones will fit the 302 and the 351 but the 351 needs a spacer adapter.

Thanks Dennis,

I ordered a better grade OEM HB and dimensionally it matches the original to a tee.

Pulled it last night using two of the three bolt holes just fine - in fact, the Ford manual photos show a two-bolt puller.

Popped the FOMOCO seal out - well, managed o get it out - and replaced it with new from NAPA.

Should have it all buttoned up and good to go tonight.

I'm so glad that thing walked off backwards on you (if it had to walk off at all)! There's a lot more damage when they walk off forwards.

Hey everybody, a 30+ year old balancer is a problem waiting to happen. There's several choices in new balancers in several price ranges, plus there's a company that can rebuild your old one (Damper Dudes).
