I employ a different measure to remove and torque the crank bolt. I remove the torque convertor access plate (six bolts) and I jam the timing ring with a long pry bar. Lets me get it off and on without using the starter. It takes me just about 5 mins to remove that cover.

 

Where these things just defective from the factory? I bought a Carfax for my car and it shows the dealer replaced it at 56k. Currently at 102k, I'm wondering how much longer I can go before having it done again.

I'm hoping the dealer installed replacement isn't the factory crap.

 

Only have it rebuilt if it's on the way out. The test is simple, really - look at my very first post in this thread ... simply mark the damper and its pulleys, run the engine, and if the mark(s) "move" out of sync with each other, the damper is de-laminating.

It's certainly not unusual for a damper to de-laminate (for any car make\model). Heck, my '64 Buick had the same issue in the past (I have 2 rebuilt dampers in the closet for it).

 

Dealers usually use factory parts so that's probably what you have. There doesn't seem to be any pattern to the failures so there's no predicting when/if yours will need replacing.

If it'll make you feel any better I'll mention that balancer delamination isn't a Jaguar exclusive.

Looking at your picture it DOES NOT looke to be delaminating. I would leave it alone until you get a LOT of shift between the dots. And I mean a lot like more than an eighth of a turn. Some where I saw one that had rotated all over the spectrium. It won't hurt anything to leave it alone for a while.

 

Not sure who you're responding to ... me?

If you're referring to my photos, yes, it was delaminated. That photo was just to demonstrate movement of the pulley(s) in relation to the balancer. Movement was up to 180* at one point (in addition to all the obvious squealing). I've already had it rebuilt (Oct).

 

I take it that there aren't any after market crank shaft pulleys for these Jags or at least a cross referenced part that will work? I see Jagbits has them rebuilt for silly money...the 250 sounds really good ...Harmonic Balancer Xj6

 

Sorry. I didn't see the other mark on the timing wheel off to the left. Good luck with the repair. Please let us know how it goes.

 

I think your best bet is removing your own and sending it off for a rebuild. If you can't stand the down-time, maybe get one from a wrecking yard and send it for rebuild...or install it and send your known-bad one away for refurbishment and take your chances with the wrecking yard model - actually not a bad idea as I've experienced 3 of these failures on 3 different vehicles thus far and it's not like you don't get plenty of warning - maybe 6 months or more between when it first starts "tweeting" and the time it starts shedding belts. So if you could hold on to the bad one without losing it in your "spare parts pile" or wife throwing it out....you wouldn't have to send it for repair if/until your replacement starts squealing.

 

I sent it off for a rebuild back in Oct. Turnaround time was one week. I installed it the day after delivery, so have been back on the road since Oct - works like a charm.

 

I had mine rebuild by Dale at Dale Manufacturing, in Salem, Oregon. Price for rebuild is $115.00 USD and turnaround time, once Dale had it, was two days.

I sent it USPS - it got to him in 2 days, 2 day turnaround rebuild, and 2 days to get back to me (shipping was about $12 each way). Nicest husband & wife team I've dealt with in a while. They offer a better warranty (than, is it Damper Doctor?).

Anyway, when i opened the box, it looked absolutely brand new !

Thanks for the tip! Very useful info! Lifetime warranty? WOW!!!

 

Do you have an updated URL to your write-up? The link above seems to be dead

Is there anyone repairing them in the UK I wonder. I have an occasional squeal on start up!

 

Try this

Don't be put off by the hokey web page. I've used this company a few times....good results in each case

Thanks.

So is there enough room to get an impact wrench and puller/installer in there without removing the A/C condenser and radiator?

I have no issues with removing the fan pack, but would hate to have to break open the A/C circuit and pull the radiator, draining coolant and some trans fluid.

.

 

I have never seen enough room for air impact but I lock the torque converter with a prybar and use a breakover to loosen the 1 5/16" bolt head.

I just got a customer's damper back from DALE and it looks wonderful (as always).

I'll install it on Monday!!!!

Yes, maybe not so much with a deep-well socket

No

As always...those extra HP's from supercharging may cost you dearly in this, as many other maint. items on the car....YMMV
But Al, whilst awaiting your damper's return, it is a great time to flush your heater core in preparation for next winter! Also an excellent opportunity to renew all of your coolant hoses....although I hear the so-called b**t**d-hose, which I found to be a bitter ex-wife to remove from the NA version, is a regular "Hillary Clinton" to change on the "R!!!"
