Supercharger oil change

Postby jonjeffryes » Tue May 17, 2016 8:45 pm

Hi all,

I have bought a supercharger oil changing kit....however the instruction show an earlier model I believe, with a removable level/filling hole plug. Has anyone changed the supercharger oil on the X350 XJR??

The kit contains the oil and a syringe for withdrawing the old oil and replenishment with new. Where do I remove/add the oil??

Thanks

Jon

Hello John.

I recall the bung with Allen hex is to the right on the front snout mounting plate to charger. With the bung removed, a thin flexi pipe on the syringe can be care fully fed into the oil chamber. Evacuate old oil and refill with new using this method. It is a fairly straight forward job.

Any other work carried out?

Thanks Mike.....I'll try this tomorrow night.

I've been pretty tied up with work and reshuffling the car set. I've now sold the BMW Z3 and the XF-R. It was a struggle, but I chose to keep the XJ as I rated it much higher than a virtually new XF...praise indeed. I've also bought a Porsche Boxster (currently in with a Porsche specialist for a quick overhaul) and I'm viewing a Mazza later this week...although that's a whole different ball game.

The Jaguar is going into James Rawlinsons' on Monday for a gearbox service, brake overhaul and suspension review. It had an engine service when the bodywork was sorted. That should set the XJ up perfectly for the European tour next month.

ooh, almost forgot....wheels will be refurbished and two new rear tyres replaced by then. All that is left is to refresh the leather and stop the drivers seat from creaking and we are about there :-)

Opening up this old thread again.

Thanks to reading Mike's various dissertations on the supercharger, I've just bought an oil change kit from Powerhouse (very helpful people).

Armed with various hex keys and the kit, I opened the bonnet. Can I find a refill plug? Can I hell as like! It's a Jaguar 2005 Super V8 and with the supercharger cover removed, I still can't see anything. Could it be hidden behind the air intake plastic pipework? I've bought a K&N air filter too so maybe I have to remove the whole air intake pipework to find the plug.

Anyone had similar trouble finding the plug or have I got a weird one-off?

Removal of the trunking back to the ali expansion plenum is required.

Look for the six or so bolts which hold the snout to the charger body. The plug is half way down on the right on the front of the plate which is part of the snout casing.

Use a half inch drive socket with the right Allen key which is part of the socket. Be warned. The plug can be mighty tight and let go with a bang. Thread sealer was probably used. So mind `yer knuckles when you first get the plug to move. Alternatively you could use a high quality Allen key and a long close fitting tube to obtain leverage.

Thank you very much, Mike. I had come to suspect it might require more work than I at first thought. But I'll give it a whirl when I have the time, maybe next weekend. I'll try to avoid skinning my knuckles too!

Regards,

I have never seen this properly explained anywhere, so hope that the following may help others:

A very simple job, made difficult by poor access, and a filler / level plug which is hard to spot, if nobody has shown one where it is. Photos, with a few explanatory notes:

Tools needed, a couple of flat bladed screwdrivers, tweezers, a 3/16" Allen key bit, a 4BA spanner, or something else which fits the drive end of the Allen key bit, a supply of rag or kitchen towel and a magnetic tray is also useful to help prevent losing things when frustrated;

Image

I run my car minus the charge cooler sound insulation, but if yours still has it, lift it off so that this is the sight presented;

Image

Remove the plastic intake trunking between the air cleaner and the supercharger, carefully disconnecting the breather to the left cylinder bank;

Image

I also disconnected the breather to the right hand bank, allowing me to move its trunking to give better access;

Image

The filler / level plug is carefully hidden; the screwdriver blade is pointing to it on the left front face of the supercharger (from the front of the car facing the engine, it will be to your right);

Image

Access is very restricted and as there is the potential for dropping the plug, or the Allen key bit, and spilling oil, I stuffed the area below with kitchen towel;

Image

Position the Allen key bit, it's very fiddly. I used a combination of tweezers and a flat bladed screwdriver;

Image

The 4BA spanner attached to the Allen key bit, slackening the filler plug;

Image

Image


Fortunately just a couple of spanner movements slacken the plug sufficiently to finish removal with fingers, retrieve the plug with tweezers as it comes out;

Image

Fiddle the tube to the lowest point in the supercharger, a stiff extension tube from a lubricant aerosol attached to the end of the one supplied with the syringe makes this easier, extract the old oil, squirt it into a disposable container;

Image

Fill with fresh oil until it overflows from the level plug, allow the kithchen towel to absorb the excess;

Image

Replace the filler / level plug. This is just as fiddly as removal, it has an "O" ring seal, so does not need to be overly tight. When it is fully home remove the kitchen towel / rag;

Image

Reassemble the intake trunking and reconnect the breathers;

Image

On my car, I noticed that there had been some light chafing between the intake trunking and some of the charge cooler hoses, so wrapped some black duct tape around those ares to protect them from damage.
