Well, after 179K miles....the supercharger on my 03' JCW R53 is finally starting to make a little bit of a growling bearing noise that's coming from the supercharger. It's still building boost just fine, but I figure it's not too much longer before it gets really bad and the bearings start making all kinds of noise.

So as far as rebuilt/rebuilding the superchargers....who's the go-to place that knows what they are doing and offers a good quality rebuilt supercharger? Has anyone tried replacing the bearings and seals in the supercharger yourself? I would think that with the right tools, it wouldn't be too big of a deal. From everything I've read...you just pull them apart, replace the bearings and seals, and reassemble them. What am I missing?

As far as just buying a rebuilt supercharger.......Outmotoring has Detroit Tuned rebuilt units for around $870..that sounds like a pretty good deal. WMW has rebuilt superchargers for around $1,200..seems pricey. Are there any other places out there that are worth checking out?

Thanks for the info!!

 

Have you done a SC service?

 

For DIY guys, repaired a R53 supercharger four years ago, using the repair kit provided by a UK company. The compressor was already replaced with a new generation, more precisely for the facelift model "Teflon coated", and only had wear on the bearings of the rotor bearings.
Unfortunately, I noticed the poor quality of some parts in the repair kit, more precisely the weak seals quality and adaptation by external bushing of 2 needle bearings. The kit was not complete, and the oil supplied by the manufacturer was a simple ATF, red, not the most good oil for this compressor. The repair kit cost 136 pounds, in my opinion quite expensive, the parts in it can be purchased with a maximum of 20$ , containing 3 bearings 6203, one bearing 6204, two needle bearings, 3 oil seals, 200ml ATF oil and a small amount of black silicone paste for sealing.
Some parts were missing from the kit more precisely, it lacks the needle bearing code HK1010, the coupling from the water pump gear, and a seal.
Needle roller bearings are not standardized, they are dedicated,the original seals are inch sizes.Disassembly and assembly require some technical skills, but not something very special, more difficult to extract the needle bearings.

 

Nope....but with almost 180,000 miles on it, I don't think putting fresh oil in the thing is going to fix the worn out bearings. I think it's a waste of time to "service" them unless you know they are leaking a bunch of oil (mines not). Those bearings have a service life, and once they are worn out...they are worn out.

From what I've seen......all that is needed when people rebuilt them is new bearings and seals (as long as the rotors aren't chewed up). I might pull it apart and check it out....I can't imagine some bearing and seals costing too much. Any bearing house should be able to source them.

 

Stiegemeier.com will do a rebuild for around $1100 plus they offer additional porting options. They also have a good reputation.

 

I would try Jokerz blower porting. They do rebuilds and porting. They've been around a long time. Great CS, and track record. They're the go to in the Ford lightning (Eaton M112 SC).They were getting better performance gains all around.

Steig started pushing the limits of the SC in the lighting platform. They started having problems and QC issues. Jokerz really started to shine around this time.

Make no mistake I am in no way steering anyone away from them. In the recent years I have heard them really turn things around.

​​​​​​That being said I have had no experience with Steig, only Jokerz. As of about 6mo ago they were doing rebuild for around half the price $600.

Good Luck

 

I can supply a brand new JCW charger... but thats no “budget solution”... but do it once, do it right ;-)

 

Sorry the resurrect an older thread, I found this while searching another topic.

I just installed a rebuilt supercharger from Detroit Tuned yesterday. I could not resist having them install a 17% pulley for me so I could just install the supercharger and motor on!

I've only put about 50 miles on it so far but it's great to be driving my R53 again and that whine at WOT...

 

The JCW superchargers are back and the price is still good, just another option. They used to have a core charge and now they dont. https://www.ecstuning.com/b-genuine-...11657556981kt/
