Supercharger isolator/ coupler wear pics
Hi all,
I just got my car back from major service where I replaced tons of parts under the hood. One of the parts I replaced was the supercharger snout and coupler (aka isolator) and then followed it up with a supercharger oil change. I thought I would post some pictures of the supercharger damage that was caused by the spring-based coupler. The pictures are of the part that the coupler sits on (coupler was removed for the photo so you could see underneath). The coupler slides over the three metal pins. The pictures are showing a top and bottom view. The arrows are pointing to gouges in the metal caused by the spring of the coupler rubbing against it. So the spring doesn't just damage the coupler it also damages the supercharger snout itself, resulting in play in the pulley and the rattling sound from the supercharger.
All the best.

And why the pronounced metal on metal rattle when logic suggested it should be just a metal on plastic rattle.

1x Manifold gasket left (AJ811590)
1x Manifold gasket right (AJ811576)
1x Supercharger plenum gasket (AJ811948)
I bought the snout/ coupler (new original Jaguar part) on eBay. Was < $300.
1x supercharger spring isolator kit (C2D38554)
If you don’t want to buy the snout, you can just buy the solid oil-filled isolator off eBay for <$30. I didn’t buy this isolator because the above kit came with a spring-type one already installed on the snout. Now seeing the damage on my old supercharger, I wish I had listened to everyone and bought the solid type isolator in addition to the snout. Oh well, I’ll have to do it again in another 9 years or 80k miles when I change out the coolant hoses again.
All the best.

No it does not.
I have had both. Your M112 Eaton or as they are better known Heaton! In my 2005 STR I never replaced the coupler and I went 132K miles on that car.
BUT do change the SC oil regularly and it's easy to do on a M112.
My 2014 XJT has a Eaton TVS R1900. Completely different and superior in every way to the old M112.

I'm not a tech, but I believe that all 5.0LSC engines are at risk. The reason for my conclusion is that the repair kit that my Jaguar dealer technician recently used on my 2013 XJ 5.0LSC was for a 2017 model: Part # C2D52713. Kit-Supercharger. Look it up online and you'll see that it's not the part number for a 2013. Apparently that kit was improved for 2017 and that latest part number fits earlier models.

Hi Matt;
Hope you got the starter problem fixed??
See if this thread will help?
SC Snout Removal
If not please post a picture or two of what you are fighting. That will help a lot!
BUT I think most people do remove the SC to get the snout off.
