Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: Supercharger Oil Service for the R53 - Discussion Thread

Mike - sorry about your SC, that really sucks. Hate to see it when these do this.

Another excellent MINI/BMW "lifetime" fluids / lubrication story. :roll eyes:

Truth in advertising - the oil in that supercharger was "good for the life of the supercharger".

Dead supercharger, no need to change the oil. Just like MINI said.

I know, I know... the problem is the seals, not the lube. But still... I hate this engineered obsolescence and "green" total-lifecycle waste reduction crap. If BMW/MINI would have recommended service intervals that treated the car as it it was designed to last 500,000 miles, then it would. Instead they treat it like it's disposable, and it is.

Grrrrrr.

 

:cornut: Yeah and brake pads during the Dragon:lol::lol::lol::lol::lol::lol::lolsorry DaveO-I couldn't resist)

No not worn or in need of replacement.

Rotate the supercharger pulley a half turn in both directions, the lobes should move at the same time, if there is any play, a nose gear is damaged. Remove the supercharger output duct, if large patches of coating are missing, most likely a bearing is bad. In either case, replace the supercharger.





Look at the weep holes on the waterpump, one is in the side, the other toward the input key, if either show signs of leaking fluid, replace the waterpump.





A fun fact, a supercharger with great lobe seal will inflate a bag with just a few rotations of the pulley by hand, and hold pressure for several seconds; poor sealing lobes will not.

 

Just FYI and it may not apply to this car but for that odd rattle and before you pull out a SC make sure your alternator does not have a cracked housing.

I thought I had the death rattle starting in my SC and it turned out that it was the alternator this past Spring before the Dragon.

THAT PRETTY MUCH SUMS IT UP! :cornut:

"an 80k to 100k service item, depending on who you ask".

Look forward to the read.

This is one of the best DIY threads I have ever read!!!!!

I found only one item that I may have either given a better explanation or omitted from the thread.
If you are curious pm me and I will tell you what it is.


GREAT WORK!!!!::

Nice job on the write up Aaron....
Great addition to the library all....

 

For the crank trigger i would just replace the O ring, its 5 dollars. never hurts to wash the front of the motor also once appart.

 

Hope people know that if your washing your engine you better have some kind of a recovery system in place. This is for sure at a shop.....but not 100% at a residence? Anyone? And I'm sure California is :crazy: :lol:

 

Ill be sure not to kill the dolphins next time. Its just much easier to deal with automotive repairs when everything is clean, I think you will agree being you work at the Custom mini shop now.

 

I don't think its regulated at residences, yet? There might be some areas that are though. But at a business, at least were I'm from it's verboten.
