First of all I want to clear something up, the full rebuild costs about 800 dollars. Oil, bearings & gaskets. Bearings according to him are custom made and of a higher quality that stock (he said it is very difficult if not impossible to source those bearings)

The guy suggested that I didn't need a full rebuild and the bearings felt like they still turned pretty smoothly. So I just went for the SC oil change. The procedure is very easy and can be DIYed by anyone handy with tools. You probably need some sort of suction device to suck the SC oil out.

Now what I was shocked was that only about 30CC of oil got sucked out. Had I not thought about changing the oil, the SC was a ticking time bomb waiting to explode imo. The cost of the oil is fairly cheap, just one bottle is enough. Cost about 100 dollars to get it done. PN for the oil is on my first post and yes its a real MB number; called a few local parts vendor to verify it before i went to change it.

So my recommendation to you all is to have it checked/changed ASAP, your SC might be running "dry" without any lubrication. Make sure you get the oils before unplugging the screw.

So here's the procedure:


1) take off the secondary air pump plumbing
2) take of the small pulley next to the SC ( if you still have one )
3) On the front of the SC and on the left side is a small hole with a screw,
you need to unscrew that , You should put some rags below it cause the oils might flow out and it really stinks. But in my case nothing...

4) use a oil suction device, put it through the hole and start sucking away.
1 bottle of oil is like 120CC, not very much.
5) The guy attached a long tube to the bottle and put it through the hole and started squeezing it out. It did take a while to squeeze all of the oil in. about 10 mins.
5) put the screw back on, ,install the pulley and plumbing and your ready to rockin roll.
