Hi all have a 2002 cooper s that I've done some work to ,well replacing the odd worn out bits ,that the last owner didn't do as not sure he was bothered, judging by some of the mots, so now I'm having to replace the Superchargers bearing just behind the pulley before I service it.
Now I'm new to cooper s having brought a couple not long ago so my question is what Supercharger does the 2002 r53 have i keep seeing teflon w11b16a, is this an eaton charger as im not sure what bearing or service kit i need to buy .

Many thanks

 

Any help for this fellow?

 

Ok found most of what was needed on ebay from the pto bearing and seal kit along with the supercharger oil, new reduced front pulley so the charger will run a little faster ,hoping it'll cool the car better with the new water.pump , just awaiting 1 bearing that didn't arrive I the kit it was supposed to be in ,then I can rebuild the snout heat the pulley to fit it as its a interference fit.and that'll be 95% of the charger rebuilt apart from a couple of bearing which I haven't been able to get too.
but hey ill find out if all is well once it's back on the car hopefully ot making any noises from the front bearing ,

 

Thanks for the update Japps. Do you have a shop or home garage? Were you able to disassemble the unit without special tools? I know this job is coming on my car.

 

Yes I'm lucky enough to have a unit so I can do the bits needed and the car is in another where my mates has it on a ramp, I used a punch which I had which about 20+ mm. To get the shafts out of front and rear housing ,unfortunately a puller I used wasn't up to pulling the front pulley off so I used an angle.grinder to cut it smaller ,and luckily enough it heat the pulley up enough for me to just tap it of , the worst bit will be heating the pulley up enough for it to slide on without having to use a press . 350 degrees so maybe I'll use my diesels heater and heat blocks to mack some sort of oven.although if your going to do it you may find a garage who can put it on for you as its around £100 for the pulley .
still cheaper to do it yourself unless you can find a place that rebuilds them for less than 1500
the only bit I couldn't do was the main body due to the vains being timed and not having a tool to lock them in place

 

In total bit for the super charger worked out at 268.00, saving me 2000 at 1 company that does rebuilds.
115 of that was for a service kit with seals and gaskets and clip to reattach the supercharger to the throttle body , needed to replace the old clips and so on . Included in that kit is a new waterpump so I thought it was worth it .

 

So those clips aren't included in the service kit? Are they easy to find?

 

There circlips which did come with the main rebuild kit

 

Thank you Japps
