Hi guys
Well had the supercharger pulley uprated and the guys noticed that the supercharger coupling has a bit of play in it but at the moment is making no noise now they have advised that on my 2010 rrss 5.0 that the supercharger will have to be removed to replace the coupler has anybody got any advice on this as there seems to be differing views on this thanks in advance

To replace the coupling just the nose cone needs to be removed as long as you can get to the seven bolts that bolt the cone on to the S/C body once the air induction pipes etc. are removed I see no reason to remove the whole S/C from the vehicle/engine.

Cheers col the guys at powerhouse seemed to think they would need to remove the whole thing there seems to be a lot of conflicting stories about how to do this and obviously it would be a lot cheaper to do the job without removing the supercharger

I do have a brand new nose cone and coupling in my garage somewhere I will dig it out and post a couple of pictures to tomorrow so you can see what they are talking about if it is of any use to you, I bought it as a spare for my own car if I ever needed one, it was around £70.00 from L/R now they are nearer £400.00 for the complete nose cone assy.

Cheers

That would be much appreciated as this is all new to me and the amount of work they were talking about to remove the whole thing was about 2 to 3 days work which obviously is a lot of labour

Nose Cone photos, you can see the coupling they are referring to, might be worth checking the shaft bearings whilst it is of as they are known to wear as well I believe, although that may a been the earlier Eaton M112 S/C not the later Eaton TVS one fitted to the 5.0L.

Thanks for the pictures I will contact powerhouse today and see what the quote is and how they intend to proceed personally I can't see the issue of removing the serpantine fan and then removing the nose cone to acess the coupling but then I'm not an engineer

Regards simon

Powerhouse specialise in superchargers, if they say that it has to come off then I reckon it will have to come off..

Granted you may be able to remove it without fully removing the charger, but it will work out quicker and easier to remove the whole thing.

I had my supercharger pulley changed by powerhouse on Tuesday and can it fault them on anything they are a great company but I think this was the first supercharged range rover sport they had done as they were surprised about clearances and how much easier the job was as I've said there are posts saying people have been able to change the coupling with the supercharger in place

As the drive belt and induction pipework etc. has to be removed in either case, would it not be logical to remove that first, then see if it is possible to gain access to the bolts that retain the nose cone just to remove that, if not then the whole s/c would need to be removed, briefly looking at the workshop manual there is quite a few bits and pieces to take off to remove the whole s/c. If it is possible to replace in situ. personally I would take that route rather than disturb the various joints gaskets etc. that retain the whole unit.

That makes perfect sense to me and would hope this is how powerhouse would see it as well when they did the pulley it looked like there was a lot of clearance once the fan was removed unlike the jags which apparently have a large amount of clutter in this area the problem as i remember came from clearance on removing the coupler as I understood it it would be connected to a shaft which also would have to be removed I may have misunderstood this I am scouring the internet for as much information as possible

Hi,

The coupling is a separate drive, you do not have to remove the shaft, it is located by three drive pins which just slot into it, it also has what I would call a recoil or torsion spring in it to cushion it when it takes up drive. I do have a vague idea it may be called a anti-rattle spring or something like that as I think there was some TSB about it failing in the early days, will see if I can find it but may well be wrong on that one.



Cheers
Col

Then to be fair I am a bit confused I will speak to them Monday and let you know the outcome I have looked for other company's who could do this but there aren't many out there

The three elongated slots in the coupling locate on the three pins on the end of the nose cone shaft, the other three holes in the coupling locate on pins in the opposing shaft in the supercharger itself.

Brilliant col that makes it Crystal clear I now know what has to be done I really appreciate your help
