BMW Mini Cooper S R53 R52 Eaton Supercharger Oil Service Kit Overhaul JCW Install Instructions Guide

Link to purchase item: x8r.co.uk/bmw-mini/supercharg...
Symptoms of fault
This is a preventative service kit to avoid future failure of the supercharger components.
The fault
Scheduled servicing of the supercharger is important to keep in the best condition and to prevent failure.
The R53 and R52 Mini Cooper S models are fitted with an Eaton supercharger. The supercharger is lubricated and partially cooled by oil located in two reservoirs within the supercharger housing.
BMW / Mini do not offer a change of this oil / service of this part as part of the service schedule. However other manufacturers vehicles utilising the same supercharger recommend servicing at 40,000 miles.
It is not uncommon for the seals to weep on the supercharger allowing oil to escape.
Most enthusiasts therefore recommend servicing every 40,000 miles to keep this oil fresh and topped up- preventing failure of the supercharger components. These superchargers are one of the most expensive components on the vehicle and used units can provide their own issues.
The solution
Service your vehicles supercharger using our comprehensive kit, prevent failure of the unit.
Our comprehensive kit includes all the parts you will need to carry out a full service of the supercharger off of the vehicle. This is the very best way to ensure a full service and complete exchange of the oil.
Our parts (developed by working on these vehicles), coupled with our thorough install pictorial and video instructions allow you to carry out this service, providing the ultimate reassurance.
We recommend removing the supercharger from the vehicle to service, we believe this is the most thorough way, all our components included here allow you to do this replacing all consumables, gaskets and parts which will likely need replacing along the way.
We recommend refilling the supercharger off of the vehicle through the drain plugs, we don’t advocate removing any of the casting of the supercharger as we feel this is more likely to introduce contaminates.
Our comprehensive kit includes the following:
210ml turbine oil. Made by Shell to MIL-PRF- 23699G and DEF-STAN91-101 standards. Matching and exceeding Eaton requirements. Enough to fully refill both reservoirs on the supercharger.
Green supercharger to air tube gasket (Vitor Reinz) equivalent to 11610020836. Failure of the seal and subsequent air leaks are common and this leads to rough running and a lack of power.
Viton O Rings (best material for environment fitted) to replace the often perished seals on the supercharger drain plugs.
Bypass valve pipe, ASH branded (select if purchasing for auto or manual so we send correct pipe) Equivalent to 17511524538 or 17517541463. Supplied with x2 Stainless steel slim hose clamps to replace OEM hose clips which are not easy to reuse (11651521321). Note our hose clamps have a band thickness of 0.7mm. Where this isn’t considered it makes the hose very difficult to fit.
Three slim stainless-steel hose clamps to replace OEM clips which are difficult to reuse on both ends of the airbox to throttle body valve intake hose. X1 to replace the clip on the main intake duct (to replace 13721491752) these hose clamps need to be slim line to fit the mounting recess correctly.
Large supercharger inlet horn gasket (Elring) to replace 17511520044. Enabling removal of the supercharger inlet horn to clean / inspect the rotor.
A pair of Viton O-rings (the best material for the fitting environment) equivalent to 11517509186 to replace O-rings on the water pump. To replace flange to block O-ring and water pump to flange O-ring.
Viton O-ring seal to replace seal on the crank position sensor (equivalent to 12147514983) This is normally leaking on these vehicles and it is the best time access wise to replace this when removing the supercharger.
60ml syringe with long filler pipe to insert oil in to supercharger drain holes.
3/16 AF long arm Allen key (not found in most socket sets) to remove supercharger drain plugs, metric sizes will not fit and will cause damage.
Dipstick crankcase bung plug, to prevent coolant entering the crank case when removing the water pump.
Replacement throttle body gasket, essential to replace when removing the throttle body unit to service the supercharger. Equivalent to 13547509045.
Bolts and washers included to screw in to the front frame to allow the radiator to be safely removed. Check out our instructions to see how crucial these are.
Replacement dip stick tube O-ring, this should be replaced when removing the tube to access the supercharger. Equivalent to 11437513891.

Superb tutorial. No daft music and clear, concise instructions. Now I have complete confidence that I can ruin my own car and save £'s in garage labour.

[@huwjones5879]

This is excellent. Will order my service kit from you guys.

[@johnrumble424]

Great tutorial, agree with comment, no music or waffle, just clear information, thank you.

Best video on supercharger...and I have seen many. I will be using your service kit. One minor correction. You mention in the video and the instructions that there are 4 bolts to remove the water pump where it is attached to the supercharger. I believe there are only 3. This should prevent unnecessary searching for the "ghost bolt". Thanks again for a wonderful video and commentary.

[@jondeegan9410]

Very informative thanks for sharing

[@Medes06]

superb video. Thank you very much

[@aircongod]

Great..thanks

[@shanevaka6737]

Awesome gotcha....from NZ...

[@timothyshaner8926]

You don't need to remove the entire wheel well liner btw; just the connections to the front bumper.

[@tobiasopseth6191]

huge help, thank you:)

[@X8RLtdUK]

You're welcome!

[@alfasudoro]

Great video. Buy it is highly recommended to replace the knock sensor as well before putting it all back together.

You all prolly dont give a damn but does anyone know a tool to get back into an Instagram account?? I was stupid lost the login password. I would appreciate any tricks you can offer me!

[@kadenlayne1065]

@Kaysen Griffin thanks so much for your reply. I found the site thru google and im waiting for the hacking stuff atm. Looks like it's gonna take quite some time so I will reply here later with my results.

[@kadenlayne1065]

@Kaysen Griffin it did the trick and I now got access to my account again. I am so happy! Thank you so much you saved my account :D

[@kaysengriffin6522]

@Kaden Layne No problem :)

[@ryandewing9483]

It should be noted that this is performed on a non AC car. Otherwise you'll need to separate the condenser from the radiator assembly before removing radiator and move the condenser to one side on the Flexi hoses.

[@X8RLtdUK]

Hi Ryan, that is a very good point! - Georgina, X8R Ltd

[@damdam8154]

Little question, I am very new to Minis and have purchased one recently, is that service something any garage could do ? I live in southern France , and have heard that BMW Mini do not get involved with superchargers, so I am tempted to buy the kit online and find someone to do it, but it seems like quite a task... Thank you very much in advance

[@ironmantooltime]

I'd have to have her use that voice on a Friday night back from the pub if you know what I mean. 😂 "Drain down the old oil into a container" - dirty 🐮

[@violentjakem]

[@huwjones5879]

What if you have A/C? Is it possible to do the job without de-gassing the system?

[@wellsyaknow]

this video is helpful too kzbin.info/www/bejne/fHKcgnyOqad6q68 not nearly as detailed as this video though

[@graemesayer3068]

You can't fully remove the rad assembly unless you degas and remove the condenser, but you can leave that all connected and just hang the front end forward to get enough clearance to work. Disconnect the rad top hose and it should tip forward OK. Stick a couple of long bolts where the alloy bumper mounts and you can rehang the assembly when you're not working.

[@timothyshaner8926]

@@graemesayer3068 You CAN fully remove the radiator. Just unbolt the condenser leaving the hoses connected. It can be hung down to the side and the the radiator assembly removed. Plenty of videos on this including Mod Mini and Wheeler Dealers..
