Harmonic balancer shot

[yakfishdave]

Hi all, the harmonic balancer has self destructed on my 2011 MN, 130k on the clock, it's at the dealer now and only just started on it this arvo, but they are saying it may have damaged the crankshaft, however, as yet they are unable to remove it, so I'm thinking this is going to be a big bikkies$$$. Has anyone had this happen?, I have asked if this would be covered under the 10 year drivetrain warranty, but they are going to ask Mitsubishi.

What do you call "self destructed" ?

Is the outer loose on the hub or has it flown apart and pulley portion totally separated?

[yakfishdave]

Maybe exagerrated there. Just spoke to the dealer, the balancer came loose on the crankshaft, whether that was because it came apart or not I don't know, but it has damaged the crankshaft, so will be a major repair, and I'll be without it for some. They have handballed it to Mitsubishi asking if they will do it under warranty, maybe replace the engine. Hopefully Mitsi will come to the party, and soon.

After having replaced my HB on my ml several years ago, as well as some other vehicles, I think you're well entitled to a warranty claim.

These things are usually a snug fit, with a key and a huge bolt that is cranked down pretty tight.

For yours to have come loose would suggest that its never been torqued up properly from the factory.

Ok, the dealer rang today, and Mitsi have agreed for them to fit a new short motor under warranty, getting the timing belt done at the same time, very happy. Using the wifes Mazda 3 to carry a heap of tools etc. is becoming a pain, but will have to stick it out for another week. Although this is the second major repair, and a few not so major, still think its a pretty good ute, will probably hang onto it a few more years provided it doesn't let me down again.

Hi there. (new member here). Triton 2005 petrol 2.4L two wheel drive. My harmonic balancer died and the pulleys receded backwards abt 1 cm - damaged the plastic timing belt cover. No aftermarket covers available, no second-hand available (they stay with the engines), and new part is about $450. anyone know where I might get a plastic timing belt cover? Thanks, Keith.

Happy to report have finally got the Triton back. New motor, all new belts, new heavy duty clutch plate, serviced, full of tools again and rear suspension still squeaking at the slightest movement. About time to look at suspension upgrade.

Great outcome yfd. Try just bending the leaf guides outwards a smidge and see how that goes.
