Balancer wobble question
Can this type balancers go bad? Mine has a little shimmy to it, and now my crank pulley is chattering on the water pump pulley.

Re: Balancer wobble question
yes they can go bad //was common in the 80's autoparts stores used to have a kit to repair the damage to the crank a wobbler balancer caused

Re: Balancer wobble question
Now will a worn balancer cause the pulleys to wobble too?

Re: Balancer wobble question
It can mess up the crank if you run it like that. Replace it before you run the engine any more.

Re: Balancer wobble question
Were the old cast crank pulleys prone to wobble? I want to get everything smoothed out down there, and this is the only pulley I have found that lines up with my PS pump.

It's not uncommon for those old 2 piece dampners to have the rubber go bad. Causing the ring to slip, or in severe cases... wobble. I would say this is a severe case. I've never seen one wobble that far off of the hub before. Gary

Re: Balancer wobble question
The center bolt is going through all the pulleys to hold the balancer, as it would not seat on the balancer without affecting the pulleys. The black pulleys hole is not big enough for a washer to set in the middle of it.

Re: Balancer wobble question
I think he means, the odd ball bolts and all the mismatched washers behind them.
Is the damper it's self wobbling or is the pully setup you have doing the wobbling. |

The damper has a slight wobble to it, but the pulleys seem to wobble more, that was my main concern, since I used a cast pulley from a 327 engine, it was the only pulley I could get to line up my power steer.

I would not drive that thing anywhere until you get that changed out, as stated above. The pulley is mounted to the center hub of the balancer and shouldn't wobble, even if the material is shot. You might just be seeing the general wobble from the balancer being bad, but I would put a new crank pulley on when you do the balancer, just to be safe. Good luck, keep us posted.

Re: Balancer wobble question
Going to place an order for a new balancer, and I am trying to upload a vid for viewing pleasure, if I can get it to load.
