Thread: Which Harmonic Balancer?

Tweet

hi, im currently building a 357 and need 2 know what to do for a harmonic balancer.

my specs are

2500-6500 RPM
10.3 compression
Forged eagle full floating rods (5.7)
Forged eagle crank


what harmonic balancer should i get? size? brand? what if i just get a decent stock one and send it in with everything else when i get everything rebalanced?

You can get a premium quality rebuilt damper from these guys. They'll rebuild yours or sell you a rebuilt one. You need to know where your timing tab is (12:00 o'clock, 2:00 or 2:30) and the diameter of the damper.

by rebuild do u mean balance? or? because we own a shop and i could probably get about 10 5gallon pales full of these things lol. i have brand new ones in pretty much 6"-8" i believe.

No Ross, by rebuilt I mean they have had new elastomeric material pressed in between the hub and the outer ring. That material breaks down over time from ozone and oil/grease and sometimes allows the outer ring to rotate in relation to the inner hub. This throws the timing all to hell when you try to time the motor with a light. We've been through several threads lately explaining to newbies how to use a piston stop on an assembled motor to find TDC on the damper because the ring has slipped. Of course, once it slips, it's probably going to keep slipping. The fix is to press new material between the ring and hub and re-clock the TDC mark back to factory. Damper Dudes will rebuild your damper for about 50 bucks. You can't afford NOT to do it.

If you have lots to choose from, just inspect the rubber layer for cracks and deterioration, and pick a good one.
