2007 XKR Supercharger Help
Discussion
You might find one on eBay. Alternatively, a chap I know local to me (Aberdeen) is about to change his supercharger for a Ken Belle one so his original may be coming up for sale soonish. He has a 4.2 XJR but the engine and charger are essentially the same, would need to check to be certain.
Alternatively, there's Powerhouse Automotive in the UK, near Sheffield. They specialise in superchargers and can do reconditioning etc. of your friend's existing one if he can get it off the car and sent to them.
What's the actual issue, any idea?

Hi 8bit,
Not sure about the exact symptoms. He just told me iy needs a new one.
I will try the reconditioned route.

A complete unit for the later 5.0 v8 cost me £2k from Jaguar , I'd think twice about buying a used one unless its guaranteed. I've dealt with Powerhouse though and found them to be extremely helpful Not sure about the exact symptoms. He just told me iy needs a new one.
I will try the reconditioned route.

OK, just I've been active on a few Jag forums (had the same car myself for 5.5 years, just changed up to a 5.0) and I'm not sure I've ever heard of a car requiring a whole new supercharger. Apart from the chap that just posted below you...Not sure about the exact symptoms. He just told me iy needs a new one.

I'd suspect the older ones rarely get checked , the later unit has to be completely removed from the engine to service it or to repair the snout bearings or coupler (both are common issues on the 5.0 with a Jag TSB covering revised parts) , mine showed some signs of wear and considering the 10 hours labour to remove and refit the blower I opted to replace it than rather do the whole lot again in a couple of years I've had the Supercharger off both my old 4.0 XKR and my current 5.0.
The 4.0 (essentially the same engine & S/C as the 4.2) was changed out on the third dismantle as the knocking noise turned out NOT to be the snout or rear needle bearings, but wear in the main central bearings which cannot be fixed at home as the setting of the cogs MUST be spot on to prevent the S/C vanes touching each other. When it came time to find a replacement many e-bay ones mentioned that there was bearing movement and there was little point in buying one of those. I ended up finding one on ebay that had come off a 4.2 engine which could retro fit onto the 4.0 engine with just a little modification to the inlet apparture.
At the time, about 3 years ago, there didn't seem to be an option for anyone to re-build these effectively in the UK, not sure if that's changed but it's why I ended up buying the second hand one from e-bay. If his central bearings have worn and are allowing movement between the main cogs he may struggle to find someone to repair.
What's the mileage on his 4.2? Does the person who's advised it needs replacing know these? Issues are most commonly snout coupler, snout bearings, rear needle bearings then central bearings - in that order. Only the central bearings can't be easily fixed and would need a new/replacement S/C unit, all the other things can be repaired with replacement parts.
With regards the later 5.0 S/C, mine started the ball bearing in a washing machine noise... I took it out and used the Jag upgrade kit (snout & coupler - £400'ish) to fix the issue which was actually just the coupler being worn out. I couldn't find the proper coupler on it's own and didn't want to use one of the green rubber doughnut versions usually sold online.
One both versions the S/C has to come off the engine to do any of this work, it's not possible to remove the snouts in situ, the bolts are not all accessible without the S/C unit sat on a bench. It is significantly easier to remove the 5.0 engine S/C than it is the 4.0/4.2. By the third time of taking out my 4.0 S/C I had it down to a 5 hour job... rahter than the two days it took me the first time!!!

I should have been clearer , my understanding is that the early charger doesn't need to be removed from the engine to change the oil , it can be done with a syringe, i don't believe this is the case on the later unit You can change the S/C oil on a 4.2 XKR in-situ, I've done it. Fiddly to get access to the plug though. I had heard that that whole unit has to come out to do this on the 5.0 cars though. Regarding the snout and coupler on the 5.0 superchargers, if I read Powerhouse's website correctly it sounds like they can be removed without having to pull the whole 'charger out?

I think I've read somewhere that it's possible to remove the snout for the 5.0 S/C in situ, but when I did mine there were at least two bolts that I couldn't see a way to reach to be undone with the S/C bolted down. And yes , you can definitely change the oil on the 4.0/4.2 in situ, just use the syringe kit available on ebay. IIRC correctly the oil top up on the 5.0 is at the back. In the 4.0/4.2 S/C the oil for the central cogs is in the space at the base of the snout. In the 5.0 S/C it's not, the cog oil is kept separate from the snout.
