Cracked Balancer

My real question... can this be repaired?

Hmmmm..... would I take a cracked piece of steel weighing about 5 lbs. and spin it up to 7000 rpm a few feet from me? NOPE

No way I would trust any repair on that.

When you consider the potential for damage, it would be foolish to reuse this part. I think you just dodged a bullet when you found that.

Not to mention the pits and the crack will make it hard for the timing cover seal to seal on the snout. You could sleeve it, of course but prob not worth it.

What they said. Throw it away or used as wall art.

Sandy,

Is this off the Runner or someone else's car?

One word. JUNK

With all of the above Otherwise

My comment is kudos to you for catching it. Great that it just wasn't reinstalled. I recently scrapped one that had a sloppy key way. No way was I gonna run it!

It's not worth it.

I spoke with "JC" at ATI at the 2015 PRI show about adding a second keyway in a mopar damper. We were looking at one he had on display, he was very concerned about how much "meat" was left for strength if I choose that option, and wanted me to find a larger front seal so he could increase damper oustide snout diameter on a custom damper. I was leary, now, not so much.

I wouldn't have an engineering problem with cutting another key way as I dont think there'd even be close to a strength issue there but that'd be unrelated to the current crack situation (as said toss it & definitely Kudos for catching that as most wouldn't as it is such a trouble free/stout piece & unless I am missing something I'd think the only reason to cut another keyway would be to reclock the dampener slit location & considering the time/money to do that (properly) I'd just get another used one as they are pretty much bulletproof (yours is the only bad one I've ever seen unfortunately).

Yes, this was on the car.

It's junk , find another.

junk!

My conversation with ATI centered (pun intended) on my use of a centrifugal supercharger overloading a single OEM keyway. The Op's broke at the keyway as best as I can tell, and is apparently the weak point that ATI was trying to beat into my brain, and it looks like they have seen this before.

Yeah in the middle of my reply I knew I was off track/missing something! kinda like way way back when I had a car that you could lock by holding the outside door button that is under the handle in while you are shutting the door only to realize seconds later that the keys are still in the ign! (& a vague thought in the middle of the 3 second event that sumpin ain't right). the gut never lies
