Lemme double check the brand used.... I think it's a GM part #

 

nope not the only, there are others that do it too. We are working with a local guy that's been doing it for years.

 

Another fix I need to start saving up for....

 

this pisses me right off! i noticed the noise at 33K


!!!! wtf!!!

 

Does this happen more or sooner to superchargers with smaller pulleys?

 

The answer seems to be no, at least with the 15%. I'm basing this off the fact that most of threads about busted SC's I am seeing are occurring around the same spread of miles regardless of pulley (OEM or otherwise).

 

We now replace the 43 tooth & 24 tooth
water pump drive gears in the supercharger. We also
a gear replacement kit. We see this problem with the gears
on the MINI supercharger quite often. There seems to be
a problem with oil leaking out of the gear case. The sealant
used seems to be the problem.

We also offer a water pump gear/PTO gear replacement kit for $325.00
Kit comes with rebuilt rear plate (bearing,seal,43 tooth gear),
24 tooth gear, shaft seal,needle bearing,sealant,oil,magnetic
oil fill plug,etc.

you just don't know where to look. I've dealt with stiegemeier on multiple occasions with my m112 blower on my cobra. they offer front drive rebuilt, water pump rebuilt and blower port, all for $895. They claim the blower port adds up to 20hp(~12%). i picked up 15% from the port to my m112.

check them out - http://www.stiegemeier.com/pricing.html

 

Not the "only" there are others, http://www.autoxcooper.com/mini_coop...d_service.html

 

From my recollection, at the time of the OP's posting, Stiegemeier did not offer rebuilding the waterpump, as Eaton was not giving out specs/parts to do so. Fast forward to now... we got choices!!!

 

Official notice: my supercharger froze!
The shop had a rebuilt one from the MINI dealer, and they wouldn't warrantee it because of the Webb pully, also it was $1,600! So, thanks to this thread, I'm getting a better rebuilt one from Supercharger Technologies for a much better price. I'll give a report.
The water pump had a small leak too, so now's the time for a new one.

 

We usually see of the superchargers we get in for rebuilding is the
gears are failing as early as 30K. The problem is the same on all
of these units - the oil has leaked from the gear box (water pump
drive gears / PTO gears). As far as I know we are the only company
that has replacement gears. We don't sell just the gears but we do
offer a rebuild kit which includes both gears, the rear plate (which is
also rebuilt), shaft oil seal, and a needle bearing for the PTO shaft.
We also rebuild the entire unit (2 year, unlimited miles warranty).
The gears do take between 250 - 500 miles to wear themselves in, so
they will make a little whining sound f until broken in.

Rebuilt Supercharger is $550.00 and the gear replacement/rebuild kit
sells for $325.00.

Hey Charles, thanks for the great service! I wish I thought of contacting you sooner...

 

Thanks, and remember that the PTO gears take about 200 - 300 miles
to break in/wear in. So they will make a small whining noise until they do. If
for some reason they don't, just let me know a we will take care of the
problem. But so far the new gears have been working out great.

Thanks again for the business!

RE: Auto X Cooper

Thanks for the correction. I could not find information that anyone
else was replacing the gears. It is good to know that someone else
is doing it right (being that we see that about 50%+ that come in
for rebuild have serious wear or complete failure on the PTO gears).
**Many of the units that come in for rebuild have 80K+ miles - unless
they had the PTO gear box oil leak.

Thanks again!

Not good news... about a bearing.

 

Give me a call at 352-542-0147 and we can talk about
the bearing issue.

 

Thanks, just did.

 

I am currently experiencing this problem. My 06 R53S crapped out yesterday during the blizzard, previous had the chatter sound coming from water pump. Upon last visit to the dealer they suspected a bearing... should I be devastated?

 

Hello Tekron, based on your other posts it's time to look at your water pump and you may want to do the t-stat and housing at the same time. Skip the dealer and look for indy shop in your area.

If Helix is near by check with them

Do you recommend anybody here in SoCAL? preferably near Temecula, CA

 

FYI - In case you don't already know, MCS sold and first registered in CA has a longer warranty through the Cal Emission Warranty... 7yrs/70k.

Sorry, don't know anyone in your region for SC rebuild.

 

My 07 Cooper S Sidewalk, was diagnosed by Princeton Mini (NJ), to have a bad thermostat. They told me to keep an eye on my temperature. They wanted $650 to replace the Thermo.

After waiting a number of weeks I heard what I thought was a chattering heat shield for a few days. Then 30 miles away, I overheated. $350 worth of tow trucking later, I dropped it off at my local mechanic.

The mechanic, who after changing the Thermostat found that the coolant was still not flowing. He then thought it was the impeller in the water pump that had broken or melted.

I got a call from him today. He told me my water pump was not working because the oil had leaked out of my supercharger, which caused the gear powering the water pump to strip out. Princeton Mini never said anything about that. Seems that there is no way of knowing if the oil is present or not in the supercharger.

He is quoting me $2000.00 for the new super charger part only. And a total bill of over $4000.00 to fix the thing parts and install.

I am pissed off on so many fronts I don't know where to start!

Anyone want to make me an offer on an almost perfect Sidewalk with it's front end disassembled?

All kidding aside, I don't know what the F*** I'm going to do. Times are bad, the bank account is 3 digits these days.

Thanks Mini Cooper Quite some marvel of engineering on that supercharger!!!!!!!!!!

I miss my 200K mile Honda Civic right about now!

F*cked ..... right in the cooper!

You can have your existing s/c rebuilt for about $700, and the labor to install it would be a lot less than $2000; your dealer is ripping you off.

 

A few summers ago I pulled my MINI's front end off & pulled the S/C to check oil levels in it. It was a long day's work but everything went well & was uneventful. If you're mechanically inclined you could pull your S/C & install a new/rebuilt one in a day. If you have the Haynes manual it's a matter of a little planning & getting a few key parts (S/C gaskets, etc.). You can see pics here.

If you're not up for this I recommend finding someone who is from your local MINI club (or local trusted mechanic) & see who can help you for a reasonable price or quantity of beverages.
