Hi, my 2005 XJR engine was just dropped to track down a slow oil leak. While the mechanic was doing this, he noticed that the main crankshaft damper / pulley was starting the delaminate with bits of the damping material coming off. I just wrote to SNG Barrett for a replacement unit and to to my horror, they replied that this is no longer available. I also searched through the web-site, and only found one past post about a damper giving way causing vibrations. Does anybody know where I can get a replacement or what is the best way to repair the damper / pulley? Does the one from 4.2 non supercharged or the newer 5L supercharged V8's fit? Any suggestions on how the solve the problem would be greatly appreciated. I have the part number as AJ89979 from my old JTIS. Thanks very much.

 

Bone yards if you have access to them
Ebay has them, but shipping could be a serious issue.

 

Another alternative is to get your crankshaft balancer rebuilt. There is a good thread in the XJ/XJ12(X305) Forum, with all the information you need.

 

Try part number AJ811117

​​​​​​​When I got the replacement engine for mine from a junkyard (ebay), it came with the crank pulley. Im sure they can be found on there.

 

The current part no at our local Jaguar dealer is AJ811116 and it fits both 4.2 NA and Supercharged motors including 2005 XJR. price quoted was $225 Can.

 

I purchased this item not that long ago and the AJ811116 is for the non-supercharged cars and AJ811117 is for supercharged cars..
AJ811116 has 1 pulley and AJ811117 has 2

I have used both for Jaguar Dampers.

 

I made an error, you are correct and it appears to be available for $337 Can

 

Thanks for your suggestion but I'm concerned that all those in the scrap yards are just as old so I expect that they will also delaminate soon, which is why I'm looking for a new one if possible. A rebuild is another option. I was just shocked that such an item isn't available any more according to SNG Barrett. If someone makes a lightweight high performance unit, I would also consider that since the original is so difficult to find.

 

This could be an option if I have no other choice.... but the car will we stuck in the workshop (again..... sob.... sob...)

 

Thanks for the contact. Worth a try to see if they have a rebuilt or high performance unit.

 

Thanks for the information. Do you happen to have their have their contact e-mail or web-site so that I can contact them?

 

Thanks for clarifying. This will help us not to mix up the two different units.

Thanks. Will give them a try.
