I just bought an xjr and got the seller to discount the price further than he wanted because I found the main drive belt was shredded on the outside (towards front of car) and was making noise on start up. First it sounding like knocking then completely went away. The biggest pulley (harmonic balancer) was wobbling. What is the best option, repair, replace, or are there any after market options available? The OEM part seems like the most expensive pulley I've ever seen

 

As of this moment, I'd be even more concerned about the bolt that's holding it on. If you can get a part number, I'd try to do a nation wide used parts search or even eBay. When you do get to the point of replacement, I'd replace the front main oil seal and the super thin o ring that fits inside of the harmonic balancer.

 

There is a shop that rebuilds the damper. It has been
mentioned here a number of times. Search will probably
find you the contact details and reviews.

If the lower boost pulley includes the damper, then that
might be an option too.

 

The shop I've used several times with great results is Dale Manufacturing in Oregon. Very hokey webpage but great service !

I'll third the repair option with the guy in Oregon, although I think he works some months, then takes other months off.

 

Or.... It can be a good time to upgrade to an overdrive pulley for the supercharger while it's being repaired for the accessory belt drive.

 

If Dale is on vacation (every few months) then Damper Doctor is in California.
