How much, if any, backlash is acceptable at the supercharger pulley? If I turn mine back and forth there is a few mm play before you can feel it engaging.

I have uploaded a video of the play. I'm assuming this isn't normal.

I have just been told that the coupler on mine has gone and that it had play where you are showing. I have also been told that I cant just detach the snout/nose to repair. You appear to need to take the whole supercharger off which sounds a big job.

I am planning on doing a complete supercharger rebuild due to this as I have done 107,000 miles now. This will mean oil, bearing, coupler change with a new 10% smaller pulley to improve supercharger engagement at lower rpm which seems an historic problem according to the forums. Range Rover Vogue SE 2007 L322 4.2 Supercharged 121k.

getting the supercharger off it quite simple, does involce a lot of steps but is quite easy, i didnt even need to put the bonnet in the work position to do it.

you will need to drain out the system of water though as this give you alot more flexibility in getting at some bits.

mine also has about the same amount of play on the pulley, i cant see any oil in my super charger unit any where? (4.2 jag)

will keep an eye on this one.

also where do you get the smaller pulley from?

Yesterday I bought a bearing kit, solid isolator and 10% smaller pulley from Powerhouse-uk's ebay shop. I'm hoping to pull the supercharger off next week and do the work.

My pulley play is similar to the one in the video above and it's not normal according to the guy that took my supercharger out in less than 30 mins today. I also need a new throttle housing gasket. I noticed inside the supercharger that the rotors are slightly marked. So a service seems a definite as soon as any sound is heard. My noise was on startup and wasn't regular. So any noise from below the pulley get it checked straight away it's probably the couplar. I will update you when my charger is serviced.

aaa that looks so familiar...

i might look at getting mine serviced as mine is similar to yours with light markings on the veins.

where are you getting your serviced at?

I am getting mine picked up by Powerhouse UK Chesterfield on Monday so will soon have her back together. Checked the hoses under the supercharger and all seems well thankfully although throttle body gasket needs replacing. Range Rover Vogue SE 2007 L322 4.2 Supercharged 121k.

Managed to get mine out yesterday.

glad to know im not the only one doing this sort of work.

once your super charger has been serviced can you let me know what sort of cost it was please?

I'm changing the bearings myself as I have a press. I bought a kit containing the snout bearings, rear roller bearings, oil and a solid coupler from Powerhouse UK and it was around £170. Ive got it all apart now - you need a press to DIY - and the bearings were all fine, just the coupler that was knackered.

have you got any photos?

have a press at work where im doing all of my tinkering

Ive been meaning to take some. I watched two really useful videos on youtube which tells you all you need to know about the snout bearings:





These are a M90 snout, but they are essentially the same as the M112. They dont show removal of the pulley, but I used the press for that too after heating it with a blow torch - that was the hardest part to remove.

So I have my Supercharger back.

The rebuild cost £350
Upgrade 10% reduced pulley size at end of snout £300

I thought the whole thing was £350 but not so when I received the bill. Unfortunately it was my own fault for not checking.

The Supercharger feels alot better. I havent properly opened her up yet. But I definately hear the whine alot more consistently than before.  Range Rover Vogue SE 2007 L322 4.2 Supercharged 121k. Engine rebuilt @ 120666 Miles

Hi guys,

I have a leak from one of the cooler lower gaskets (driver side)

To change this I need the charger out to access the bolts. How much of the cooling system can I get away with leaving? do I have to take the whole metal thermostat housing off the front?
