Need some REALLY good glue:
Is this even possible?
I'll skip the long story but my trusted assistant managed to shave the dampener off of a crankshaft pulley. (By improperly bracing it while someone else (ahem) tried to break the bolt loose. Just one of those bone-headed things that can happen in the heat of battle with a mechanical beast. He said, "Oh! I've got it!", as in, *I found a way to brace it*. I did not check his discovery and this was the result. I guess that is the long story.  It's from a 3.0 Mitsubishi V-6, if that matters. (It doesn't). A new pulley is ~$350.00 dealer list. The break is clean, (the two parts fit together perfectly), is there anything that will bond vulcanised rubber, or whatever the ** this is? There is really no force on this thing once it's installed. TIA as always!

Wow, rigging that back together sounds like trouble waiting to happen.
Since it's a balancer/damper, I think there's probably a ton of vibrational force acting on it most of the time. I'd be surprised.

Man up, buy the new part...whoever owns this car deserves it...

Check a salvage yard for a used one.

There is no fixing that one. No way.
Here's a bunch of brand new ones for under $100: |

No, I wouldn't glue it. But, it looks to be held in compression when the cover is bolted up. Why not back fill the cavity with some high temp silicone and install? Wait a day and fire 'er up.

Harmonic balancers are designed to dampen vibration at critical speeds.
i.e. every piece of rotating equipment has a critical speed where the natural resonance of the rotating parts matches an excitation force, a certain running speed. In other words it's like ringing a bell. A bell rings at a certain frequency, and when an external vibration is at the same frequency they will amplify one another significantly. That vibration can become severe enough to damage the machine. A harmonic dampener is designed to lessen that effect and keep the machine from breaking. It's not something you should mess around with. A broken and glued one will not dampen as designed. Get a new one or a good used one and put it on and sleep well. |

That comes "unglued" at 4,000 RPMs and it's going to make a big mess.

Thanks, everyone! Wound up getting a good used one @ a junk yard. Would have been near impossible @ self-serve junk yard, you need a very strong impact gun to break bolt loose.
$100 fk-up. The car is mine, FWIW. It fell into my life w/ a bad T-belt tensioner that made it sound like it had loose parts floating in the valvetrain. It will be fine when fixed tomorrow. Thanks again!

You don't have air tools? I hate working on other people's old stuff for just this reason.
Yeah, what the others said. The issue is the function of dampening harmonics. If it doesn't work as designed any more, the crank bearings will go out. Good Luck - George |

In fact, I have really good impact guns and a pretty decent home compressor. It just did not have enough torque to bust that (over-tightened by last idiot) bolt loose. I put it back together enough to drive and brought it by my buddy's shop up the street where he instantly popped it loose with his gun, which is hooked-up to a compressor and tank the size of a car. Their compressor runs all of the air for his exhaust shop plus a very large body shop next door. It is not even in his place, lines come from next door.
That's what you really need for situations like this. It never occurred to me that I would not be able to get that bolt loose or I would have just brought it by his place to pop it loose before starting. Oh well...
