Super charger rattle repair.

Has anyone had the supercharger drive coupler replaced, and can give me an idea of cost for the job?

Mine is starting to chatter when the engine is cold. I haven’t got time to diy right now, so thinking about sending in to be done. Reading up on the job, it looks like it’s a supercharger removal, and there’s a few other jobs that are best done at the same time. Coolant pipes and oil change for the supercharger.

If I leave it, will it do more damage or fail completely?
 
Hi Gareth,
Before you crack on are you sure it’s the coupler and not the snout bearing?
 
No I’m not sure. All I know is that on a cold start it’s a bit noisy, irregular clattering. It mostly goes away after it’s warmed up.

I’ve read lots about the spring-dampened coupler that fails. Many say replacement with a solid replacement cures it.
 
My v6 is always very tappy and clattering on cold start but goes away as soon as it gets warm. (Therefore its obviously worse in the winter).
It has always been like that (5yrs and 36000 miles from new) and understand its a characteristic of the engine as it doesn't have hydraulic lifters or something.

Search the forum but I thought the characteristics of a worn coupler or snout was a pronounced clunk up to a second after the engine is switched off.
 
Fellow member, Tim, had exactly this issue. I’m sure he’ll be along to confirm. Tom Lenthall carried out the repair & the water pipes too. Think cost was quite reasonable.
 
Hi Gareth , it would be better to get car booked into ither a dealer or jag Indy for confirmation just in case it is the bearing , but the supercharged unit will need stripped out if me I would get them both done whilst it's off and of course a new belt and fresh oil as well as pipes , hope it's not to costly mate keep us informed

The attached Jaguar bulletins should give you all the info you need including a summary of the 'clattering' noise you are hearing, the possible cause of the noise, how to check (by removing the supercharger drive belt and rotating the supercharger pulley by hand / Noise, Vibration & Harshness test - Accessory drive belt Diagnostic procedure), parts details, time required for the job to be done etc.

This official Jaguar link is for the F-Type 3.0 Litre Supercharger parts.... https://parts.jaguarlandroverclassic.com/parts/index/part/id/C72.C7219.C7219242.C72192429831/brand/jaguar/

If you wanted to buy good quality non main dealer parts, Powerhouse UK sell parts/kits/services for the F-Type supercharger and they have an ebay shop. The following information on the Eaton Jaguar TVS R1320 (V6) and R1900 (V8) superchargers is taken from their main website https://powerhouse.uk/supercharger-parts-rebuild-kits/eaton-jaguar-tvs-supercharger-rebuild-kits/

“On the TVS supercharger, rattling at idle is the first indication that your coupler is failing or broken. Continued noise may indicate that a bearing is starting to wear. The important thing is to have a supercharger repaired when you hear early signs of something being wrong – if they are left rattling too long damage can spread from bearing wear, which is curable, to wear of the rotors and/or main casing, which can become bad enough to scrap the supercharger.”

“The Achilles heel on the Jaguar and Range Rover TVS is the sprung drive coupler, if you have a rattle at idle it could very well be this. The coupler spring wears against the shaft until it breaks and badly wears the shaft as pictured. Our uprated coupler removes the spring from question and works on worn shafts without issue. Simply renewing for a sprung coupler will only end in the same fate. Our uprated oil filled nylon couplers start at just £38.”

Here’s a couple of links from their ebay shop for the F-Type V6....

Additional to the JTB and SSM that RPSN has posted you should also be aware that a ticking fuel pump noise can be transmitted by the fuel pipes from the bottom of the engine to the injector rail and give the impression that the noise is coming from the supercharger.

It’s unlikely to be a ‘ticking fuel pump noise’ as this would also be there when the engine is warm. The OP is hearing an irregular clattering noise when the engine is cold and it mostly goes away after the engine has warmed up.
 
Yea i had my go, sounds very similar.
I'd get it changed and whilst doing so, change the supercharger oil and the water pipes under the
charger and the water pump.
 
It could be that the ‘clattering’ noise the OP is hearing when the engine is cold (which mostly disappears as the engine warms up) doesn’t need any attention. Many F-Type owners experience the same/similar issue which is quite common on these cars.

If the noise continued when the engine is warm and idling, then it’s a sign of wear on the supercharger components that I mentioned earlier. However, this doesn’t appear to be the case here.

I recall the OP’s car being an early model (approx 2014/15). Out of curiosity, I’m wondering if the correct Jaguar Land Rover certified engine oil is being used i.e. SAE 0W-20 meeting JLR specification STJLR.51.5122?
 
Yes it’s a 2015 model. The correct oil is used, however, I don’t think the supercharger is lubricated by the engine oil, it had its own.

I’ll hold off getting this job done as it sounds like others experience it, and it could be a feature.
 
Considering this engine has been produced for a considerable number of years now you would have thought this would have been fixed by JLR !

Yes, the supercharger has its own oil. The reason I asked if the correct engine oil specification is being used is because the ‘clattering’ noise you are hearing when the engine is cold mostly disappears as it warms up and the oil has circulated. These engines appear to be very sensitive to the oil spec used.

I wouldn’t be too concerned about the issue, due to the reasons mentioned in my previous reply. Worth keeping your eye on it though, in case the noise becomes a lot more prominent or if it remains when the engine has warmed up.

That’s one less job for you to get done :)
 
Hi Plymothian!

I've got the same noises appearing again on my 19 plate V6, did you manage to get to the bottom of what is causing this? My supercharger was replaced last year but I still have these noises...local dealership at a loss.....

Thanks
Robin
 
I have a rattle, I'm sure it's the supercharger coupling . My question is. Is it ok to carry on driving. Will it fail completely and if it does what's the worst can happen.
 
Hi Chaps. No I never did get this cured. It went to a reputed independent Jag specialist here in Stockport and I was advised to leave it. They said it was very common on these cars. They said I would only need to worry if it starting rattling when warmed up.

5k miles down the road from original post, it’s no worse. I am keeping a close eye on things, especially for water leaks that would indicate failure of the ‘Y’ pipe, which I have been reading is almost a certainty at some point in the near future. When this happens I’ll justify the removal of the supercharger to get it all done.
