I'm having serious issues finding this part. It's going bad on my car and I can't find the part locally or online either!

Can someone guide me in the right direction?

Looks like a pulley to me, at least what I see equivalent on the EPC. Strangely, it is not valid for my VIN!

A 132 030 00 68

Searching use "1320300068".

$135 - for the work involved in R&R, I wouldn't replace with anything but NEW as the failure is usually from heat and stress.

Over time the energy dissipating element (elastomer/clutch/fluid/spring) can deteriorate from age, heat, cold, exposure to oil or chemicals. Unless rebuilt or replaced the device could fail and possibly cause the crankshaft to develop cracks.

What you are looking for is not a harmonic balancer, it is a pulley. Why do you think you need a part the car does not have? Probably because somebody gave you a wild guess without knowing anything about the car. If this is about the shaking you posted about in another thread I think you are barking up the wrong part.

I've never heard of having to replace a harmonic balancer on an engine. It's purpose - on the engines that it is used, is to reduce engine vibration a bit, and often has integral balance weights or drilled holes for fine-tuning the crankshaft balance - these can't "go bad".

The quote from MB DNA comes from a Wikipedia article whose accuracy looks suspect to me. I seriously doubt that a harmonic damper whose rubber/elastomer element has hardened could cause a broken crankshaft.

In all due respect you apparently haven't spent much time around engines!
I have seen and replace them when the "rubber" for lack of better words has gone bad and they have spun, have seen them come apart and have seen them crack.
They "can't go bad" ahhh WRONG!

Okay, so GM V6 3.3L/3.8L never had such failures and I didn't replace one on my Oldsmobile?

Right . . .


But then again, if you are talking about your ED you could be right?

I think within the last one or two years I replaced the alternator in my W201. Strangely you are supposed to replace the fan, because of metal fatigue. I ended up changing it. I didn't want to "argue" with the manual, even though the completely metal fan looked perfectly fine to reuse to my naked eye....

Anyone got an X-Ray machine to check???

How does a fan blade slicing through the radiator sound?? If they say to replace it, I would do it.

I have seen the fuel pump on my old Corvair leak fuel onto the harmonic balancer and the rubber got all messed up. I bought a car that wouldn't run, acted like the timing was off but the mark was exactly where it was supposed to be. Turned out the outside ring on the harmonic balancer had moved a bit and threw the timing mark off. I re-timed it by ear and drove the car home after I bought it. I didn't know the harmonic balancer could move like that. After that, I seemed to find a lot of them that were all swelled up or cracked. Not that uncommon

I would definitely be crying if it did break on me! At first I put it back on and tightened it to spec. I had to use a breaker bar with a piece of metal pipe on the stone floor to get enough leverage to take it apart again and put the new one in. (Same method I used originally to take the old one apart). I never thought of that. That makes me feel a lot better about all the work I did to take it apart again...

I kept the old one because I didn't know what else to do with it:

I never replaced them on any of the small-block Chevy's ('67 Impala, 68 Camaro) I've owned and souped-up back in the 1970s. Nor did I ever hear on anyone else replacing them in Fords or Mopars. They mustn't make cars like they used to...

Can't speak for Mopar but some Fords were internally balanced so didn't need a harmonic balancer.
I have seen/had them slip on early Fords.
