I have searched but cant find anything. Is there maintenance that needs performed on the supercharger? (2007 XKR). Oil, coolant, etc.?

 

There's no cooling system for the SC - there's air-water intercoolers beside it, but they're part of the main cooling system (separate but connected).

There is lubrication for the SC; I think it's "sealed for life" according to Jaguar, but one of the Eaton resellers says (about the TVS 1900 unit used in the 5.0) "Only requires an oil change every 80,000-120,000 miles". It's a bit like the gearbox: it officially needs no attention, but the component manufacturer says it will benefit from servicing at higher mileages. There's a filler plug in the TVS rear bearing plate - the 4.2 manual doesn't talk about a filler in the M112 SC, it just says "The supercharger has a sealed-for-life internal lubrication system". I've seen people talking about changing the M112 oil online, so it must be do-able.

 

Ross, you're a great asset to this forum.

 

Weeeellll - I've still had to correct that post about 5 times, but thanks

 

Oil change on the M112 is possible, lots of threads in the XJ sections about it.

There's a filler plug on the front of the housing.

In fact in the early days there was a scheduled oil change in the Jaguar documents.

Many of us have changed the oil in the SC. You need a syringe to suck out the old oil, there are kits on eBay for this from Powerhouse in the UK.

 

GM uses Eaton superchargers in a number of vehicles.

They don't claim sealed for life. Their service interval is 30K miles.

 

Thank you all for the info.


I guess "If it aint broke..."

 

Well, the thing about preventative maintenance is that you're supposed to do it before it's broke.

I'll certainly be getting my transmission fluid, filter & cable gaiter replaced if I get to 60k miles. I doubt I'll see 80k, so the SC lube change isn't something I'm likely to worry about.

 

Hah! Yes preventive maintenance, but not something I need to do right away is what I meant.
