Harmonic Balancer wobble
 

I got a 260 V-8 off of a '64 Ford Ranchero, and when the engine is at idle or a little above idle the harmonic balancer wobbles a bit, and causes the engine to slightly shake. When I had the engine rebuilt I had the shop balance it for me. However, once you get up in the RPM's the wobble stops. I was wondering if anybody knows if this is normal on this engine or not? And if it isn't is this a serious problem?

The only engines that would be normal on now have broken cranks. It is a VERY bad thing, and needs to be replaced yesterday, if not sooner.

HEY !!! Are you ASE Certified ??? If you are, ask me about iATN.

Thanks for the quick reply. One more question. Can a 289 harmonic balancer be used for the 260?
