Harmonic balancer install

[Hard Charger]

looking for a harmonic balancer install tool.

the bolt is 3/4"-16

had no luck finding a bolt that size with tall threads

any ideas?

You should not need a tool to install. Many performance aftermarkets require honing prior to install to account for manufacturing tolerances between brands.

I rented the install set from AutoZone and liked it, so I kept it. It's good quality and a little cheaper than I found online. Not only does it have all the pieces you'll need for most engines, it has the ball bearings too that helps with friction.

Tap it on far enough with a block of wood and a hammer & when it's on 1/4" - 3/8", you can just drive it in with the factory bolt.

  Been doing it that way for years. If the damper hub isn't a good tight fit on the crank it can cause fretting of the crank snout. AMHIK

Tap on a block of wood yes, smash with sledge or use an impact on an installer- no.

any ideas?

If possible let the garage/engine get cold. Heat dampener hub with propane torch for 15-20 seconds and it will usually slide on far enough to finish with the bolt.

But yes, if it's an aftermarket dampener (ATI usually seems the tightest) you may have to hone as Joe suggested.

I too have tapped them on enough to use the bolt, but the install tool is cheap enough to buy, or you can rent it for free. And you don't have to worry about damaging the threads in the crankshaft.

Stock balancer - tap it on and thread it up, or

Mancini has a longer bolt, or

Buy install hardware, or

If ATI, have it professionally honed to fit

You mean I could market the fine thread aircraft bolts I have as a balancer install tool?? I'd better get right on that! What's Mancini charge for a 3/4" (or was it 1") bolt? I probably have a 1000 of each size.

great advice
thank you.

i ended up buying the same kit that is posted. Bought it online for about $36 delivered. Did the job fine.

I have a older 383 with 3/4"-16 crank bolt an it was difficult finding a kit to fit this. Was also having trouble finding a bolt and nut to make my own. Found a bolt but the nut was difficult.
