Hello,

I have bought a rebuild kit for the supercharger of my 95 XJR. I thought it will be easy to remove the supercharger but it appeared that I don't have access to all the bolts and I have to remove a lot of things, including the front suspension, only to gain access to all the bolts, which looks ridiculous.
Has anyone done this before and is there a way to access the bolts without removing the front suspension and so on? Maybe there is a thing I don't know.

I'll be more then happy if you share your experience with me.

 

I haven't done it myself but I've been looking into doing it also but why do you think the front suspension needs to be removed to access the supercharger?
From examining the set up I think the air intake assembly/intercooler needs to be removed and you'll get full access to the throttle body and supercharger itself...

 

Here is a photo array showing replacement of the octopus hose but it also shows the engine with the supercharger removed....which might be helpful to you. I agree that removal of the suspension shouldn't be required.

I haven't removed the intercooler, yet, but it seems that it will hard. There are a lot of cables passing from there. Also, it looks like, even removed, there is no access to the downside bolts. However, from the pictures you send it appear that I am wrong. When I remove the intercooler, I will write again to say what happened.
Thank you!

 

Urchins,

It would be great if you were able to take pictures of the process and a brief write-up so that JaguarForums.com can put it in the 'How-to' section (https://www.jaguarforums.com/forum/x...k-links-20088/) and benefit others who may need to do this in the future.

Thank you in advance

 

Hi can I add my 2 cents worth.

I have fought the octopus on my XJR6 and won, as both the bottom hose and bypass hose had developed weeps on the joints due to the spring part of the hose clamps rusting away and releasing grip on the hoses.

To achieve this I did take out the Air intake assembly, coolant hoses, tank, and metal 2 way link pipe (below air filter) and outer hose barb off the intercooler; then oil filter, throttle body, super charger but by access from underneath in a shallow pit. At no time did I consider taking out the intercooler.

Certainly it made access to the supercharger easy enough to consider a revisit when/if I get around to porting it. It also provided easy access to the coolant drain plug to be able to flush the whole system several times as I was changing the type of coolant to Prestone and I wasn't sure exactly what was already in the car. Also it is a lot safer than having the car on Jacks for a couple of weeks as my time is limited with a house extension/rebuild on going.

 

My mechanic warned me off Prestone.
I am not sure why now - that was two years ago.
He sticks with the OEM specified coolant.
Maybe be wary of Prestone.. others will be able to comment better

 

I have removed the supercharger, without removing any suspension parts, but I had already removed the inlet manifold. If the two lower studs that hold the supercharger onto its bracket start to unscrew as you try to remove the nuts, then you won't be able to get the supercharger off, until you are able to remove the nuts. The two upper bolts should be straight forward.

 

Hello,

Because the work wasn't done by me, but by my mechanic, I don't have photos of the process...
Finally, what he did is to remove the intercooler, the manifolds and after that accessed the supercharger. The supercharger is now rebuild. The coupler, oil, bearings, etc. are changed. The coupler was on pieces, as seen from the photo.
After staying at the dealer for an year, for change of the ECU, ECU's harnesses, supercharger rebuild, starter change, A/C radiator, fuel pump, all the pulleys and some other things I took the car, after which the hose connecting to the water pump blow up and I returned the car back to the mechanic...
Now the supercharger is almost singing and the pleasure of driving is unbelievable, but what is strange is that with the new computer, which is exactly the same part number, only fewer months newer (27/09/97 for the new one and 01/01/97 for the old one) the car is calculating strange data. It is giving me 9l/100km in the city and a range of 150km. I made a test after 50km I added fuel till reaching a full tank again, and I was able to fill in only 4,7 litres, which means it is true, but I doubt it...
Even as new the car is consuming 17l/100km.

Now I am waiting for the new hoses and I'll see how the car is behaving. To be sure I will go for a computer check.

Also, when the car is not in a move the instant fuel consumption is 0, rather then before when it was showing 199.

P.S.
I will ask the mechanic if he has made any photos and if he did I will upload them.

 

9litres/100km is 31.5miles/imperial gallon, which seems miraculous. I wouldn't have thought it would be possible to achieve such a fuel consumption, without driving it at the lowest possible constant speed at which the gearbox (I'm assuming the car is an auto) will stay in top gear. I have two manual XJRs and the best that I have ever achieved in really gentle driving is 28.5mpg.

 

Its a lot of work




cleaned everything while it was off the engine

 

I managed to get it all back and running again
