Mini Cooper S R53 R52 JCW W11 Eaton Supercharger Oil Service Kit with waterpump

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.
