Does anyone know of a complete rebuild kit for the M45 SC that most of us have in our cars? It's really hard to trust these small part suppliers on ebay etc.. Was wondering if anyone on here has rebuilt their supercharger as a DIY.

 

Have a full machineshop in your garage?
To rebuild s m45 it must be dissembled, cleaned, remachined , then the hard part, retiming the rotors....a few folks have just swapped the snout bearings (which almost never fail on the mini) and the plastic sheer clutch in the snout...but the parts that fail need some real skill/tools to get too...the pto. Beyond an oil change, not sure what can be done that may do more harm than help. Sorry to sound like a buzzkill, but sometimes 50% of issues posted hete can be self inflicted.....

 

Timing is everything. Here you go

Surprised none of the after market companies haven't come out with an electric drive water pump to no longer use the pto gear, and remove it form the housing' would also take some resistance off the rotation of the supercharger........ oh, another brainstorming idea to make lol.

 

There are....
But the simple fact is the sc is a WEAR item, and it looses efficency as the rotors wear, and changing the seals, and relubing does NOTHING to get the lost PSI back...a real rebuild in a machine shop does....and many folks have gone 150k+, no sc relube...either it was made right, and lasts till you need to rebuild it, or it leaks out, and has to be rebuilt.

 

Well hope mine was made right. Opened her up around 83k and not a drop of metallic shaving inside, and still full of lube in both ends. Made sure it was torqued back to factory. Could using smaller pulleys be a concern point as far as the rear seals go, possibly prematurly wearing them out, or heating them up to a lesser tolerable degree then initially built for? I would love to put a 15% pulley on the wifey's mini, but with 90K coming up, I fear the seals would begin to leak.

 

I sent mine off to autoxcooper in August from Canada.. I have a 2004 MCS.. all I have to say is AWESOME!!! very good experience .. I did all the additional work to my SC coating rotors etc that they offer..

I had mine done by stiegemeier! Did a great job also powder coated it and port and polished the inside

 

This is great. Can't wait to here your results once you get it on.
