UDP's Balancers and that ever long Debate...

[Z28pr0jekt]

I call shenanigans on that.. idk.. I can't imagine my balancer has much left to that ring and my motor seems fine (for the most part haha)

i mean in the pics do you see a rubber ring on either of these? its hard to tell as they are all black

Thats because on those from what I was reading that ring is inside on some of them or they may have a different design.

Remember many cars from Mazda, Ford, Chevy you name it have the same rubber ring setup. Its most likely cheaper but you tell me then;
How does a Metal Object absorb Tors. Vibration?

[Z28pr0jekt]

I couldn't answer that as I'm certainly not any type of engineer haha.

But how does an 1/8inch thick deteriorating rubber ring absorb vibration? haha

Not trying to debate this so I think I'll just shush for now as I'm definitely not the most knowing here

Actually you hit the nail on the head, thats what I have been asking for some time.

Here is some information about whats going on if that ring was working correctly:
Again a Copy and Paste from 1994Z28Lt1:
Otherwise known as vibration damper, harmonic balancer is a device attached to the vehicle’s crankshaft to minimize torsional vibration. As the cylinders fire, the crankshaft transports the power. The front section of the crankshaft suffers from the impact of the said power, due to this, it often moves before the rear part of the crankshaft. And this movement yields a twisting motion. Once the power leaves the front, the halfway twisted shaft unwinds and then snaps back in opposite direction. Even though it is small, the unwinding process gives torsional vibration.

To minimize this vibration, GMC harmonic balancer is employed. This vibration damper is made up of two pieces attached together by rubber plugs, spring loaded friction discs, or both. As the power coming from the cylinder gets to the front of the crankshaft, it attempts to twist the harmonic balancer’s heavy portion. But it usually ends up twisting the discs or the rubber joining the two damper parts. The front portion of the crank can’t turn the way the damper did because the force is being consumed in twisting the rubber and speeding up the damper wheel. And this causes the calm operation of the crankshaft.

GMC harmonic balancer doesn’t just act upon vibration. It also helps in extending the service life of the engine by reducing wear on the main bearings and journals. Plus, GMC harmonic balancer helps in preventing defects and failure on the crankshaft. It is great preventative maintenance for your GMC vehicle to replace damaged and defective GMC harmonic balancer. So if ever you notice that your original GMC harmonic balancer is already defective, have it replaced immediately
