To have on of the jobs done on my car the SC has to be removed, I wont renew the belt or tensioners as those are pretty new (less than 6months) but if any one has had this done what was the parts list of things needing replaced. for example what gaskets, o-rings etc are needed? Does this one have the "valley hose|"?

One my list so far is just the SC oil that will be replaced of course but just need some guidance yere for example are the inlet manifold gasket needed? Are the plenum chambers have gaskets or o-rings.

Any help is appreciated

 

It would help a lot if you showed the year and model of your (I assume) XKR, as the later ones (2009/10 onwards) had a completely different engine and supercharger to the earlier ones. 5.0 litre AJ133 V8 vs 4.2 litre V8 and Eaton TVS R1900 vs Eaton M112.
The list of parts that need replacing may be the same or they may be different but either way they are completely different parts.

 

@Jaguar!2 owns a 4.2L 2008 XKR according to his Public Profile. It would be helpful to put that in your signature so we don't have to keep looking for it.

Sorry yes its a 2008 XKR 4.2

 

Your s/c is the Eaton M112 Gen V.

Thanks that is something I will have done at the time. All this is to access the fuel rails to stop the leaky dampers hence the S/C has to come out. It anyone know of the other gaskets, o-rings etc that might be needed it would be very much appreciated. I have some silicone hose whihc live under the SC orders to just update them.

 

Yes,
coolant valley hoses, https://www.jaguarparts.com/v-2008-j...oses-and-pipes
Super charger fluid. get it from ford or gm. its the same stuff.
Connector tube. (just the rubber piece) https://www.jaguarparts.com/v-2008-j...ne--air-intake
(you will find many threads on this here)
While its all apart, its easier ti get to spark plugs, pcv valve, injectors etc.

 

I went through the exercise recently for refurbing (most of) the S/C, replacing the intake & S/C gaskets, replacing the spark plugs, replacing plastic coolant pipes, and other things.

Here are some items which I purchased, which also seemed to be of decent quality:
- S/C refurb kit (oil, bearings, coupler, etc.)... https://www.ebay.com/itm/126179733635
- Snout rebuild kit (note: not OEM, but still definitely better than my 65k original snout; also, I didn't use the coupler from this kit but the one from the kit above)... https://www.ebay.com/itm/186514025284
- Intake & S/C Gaskets (I chose the Meistersatz manufacturer options and I was happy with the quality of the gaskets)... https://www.partsgeek.com/catalog/20...ld_gasket.html

Hope this is helpful. Good luck.

 

When does the supercharger typically need to be rebuilt? I'm at 75k miles and about to have the supercharger out for leaking valve covers.

I haven't heard good things about replacing the spring coupler with a solid coupler... Seems like they commonly lead to premature wear and excessive noise.

 

Mine is the 2008 but its a job to remove so this will be off loaded to a trusted mechanic I know to remove it on mine he said 4.5 hours just for this, I have looked at hoses underneath and got silicone replacement, inlet manifold gaskets, SC gasket some other rubber coupler/seal £77 worth and the rebuild kit another kind forum user linked and the coupler just in case. its the snout bearing and another that comes in the kit along with 225mm of SC oil. I am in for around £350 - £400 in parts. still don't know if that would be everything think I need coolant as that will need draining. Plugs were replaced just last year so should be good.

But if you are going that big as someone else advised do the timing tensioners need doing? if the SC come out think, belts, idle wheels and belt tensioners

 

Now at 200,000 kms. No issues with the supercharger. None.
I have been changing the fluid every 50,000.

 

I'm not sure about "typical" timeframe, but I can tell you that my XKR had the spring coupler go bad around 55k. When I took the S/C off for the repair, I discovered that the impellers definitely had more wear that I was comfortable with. I'm guessing that either the broken coupler and/or worn bearings caused the impeller damage. The damage wasn't extreme, but you could see that the coating had been rubbed away and the shiny metal underneath was visible.

As far as the coupler choice goes, I think you have to choose the lesser of two evils. You either replace with a spring coupler, knowing that it will wear our quicker than the solid one. Or you use the solid one knowing that it might cause some more wear on the rest of the S/C. From all of the research that I've done, most these days opt for the solid coupler. The spring coupler IS a known weak-point of the S/C design. I'm sure that folks on the forum will chime in if they disagree.

 

I wish that I were that lucky! I inherited the broken spring coupler issue from the previous owner.
