Just heard MB Pulley cause cancer in lab rats too!

I have a full Renntech kit with matched springs and shocks. Sway bars and adjustable camber and toe bushings. The car also has 18 inch wheels. It handles great and the ride quality is not harsh. I'll take a picture and post soon.

I WOULD TALK TO ANOTHER MERCEDES DEALER!!!!

AS A EX FACTORY (RETIRED)MERCEDES TECH I HAVE seen several go away and make a big MESS !!!!

SO ITS NOT SECOND HAND !!!!

AS I STILL HAVE FRIENDS at SEVERAL (LARGE)MERCEDES DEALERS and they ARE STILL REPLACING LOWER CRANKPULLEYS/DAMPNERS AFTER they FAIL

SO its safe to say there IS a PROBLEM with the PIECE
and A SOLID PULLEY WILL FIX THE PROBLEM

AND BENZMAC IS CORRECT the PROBLEM IS THERE!!!

BTW..... THE PULLEYS (MOST OF THEM ) WILL FAIL UNDER
WARRANTY SO IT WILL COST you only GRIEF

The crank pulley is the same part number for the 3.2 v6, 4.3 v8 and 5.0v8. Check for yourslef! No one said the crank pulley is the same for the 4 cyl.

KLEEMANN has never resorted to bogus claims to sell its products. I was unaware that Mark Cummins was an employee of KLEEMANN, nor did I see where in his post he was stating that his words were KLEEMANNS words.

KLEEMANN has a pulley that incorporates the factory pulley for those of you who wish to keep it- no one is trying to scare anyone into a purchase.

SO..... Since we are talking KLEEMAN (NO I DONT WORK FOR THEM) NOR was it STATED (THATS SECOND HAND)
Just telling the thread about a GREAT PRODUCT that WORKS!!
THATS WHAT THIS IS ALL ABOUT RIGHT?

Yes that what its all about.

Somtimes the transfer of info gets a little bent the more people it goes through, just trying to "officially" state our position

So if we are talking about a C230K why are we told about problems with other parts that have nothing to do with the car in question?
It seams off hand that, that it is an effort to post disinformation as fact. The facts are there are not lines of C23ok’s 2002 filling the parking lots of Mercedes dealers because of dampeners failing. And yes Kleemann it does appear that you and Mark are bating it back and forth a bit.

The point in posting about certain failures is in direct response to threads on other boards. There are several threads going on with topics like what about the damper? Doesnt eliminating cause a potential problem? In explaining why it does not I used the analogy of the V6 and V8 cranks. How can three diferent displcement engines of different cyl configs possibly use the same pulley? Simple- the "dampner" is not a "balancer" or any other such misnomer. The elastomer in the pulley is there to quiet accessory noise transmitted through the belt drive. Eliminating it is not inhernetly dangerous to any engine. Then comes the verified observation that there have been some pulley failures on standard cars- why is this important? Its the same principle used in every MBZ crank pulley, thats why. Just another tidbit of info to bolster the idea that ANY part can have inherent problems or positives.

None of this is misinformation spun to sell product- KLEEMANN has a solution for either scenario- what possibly do I have to gain from shucking BS other than bringing a bad name to our products???????

Everytime a happy customer posts a positive review of our products will we be accused of having people in our pocket?

Wow, I leave for a few minutes and everyone's fighting...

I'm just kidding. Personally, I have an engineering background so I naturally want to do all the research I can before making a decision. I have received emails from Renntech with specs about their pulley system. I really would like to see some specs for the Kleemann pulley as well. I'm mainly concerned with how many more PSIs will the enlarged crankshaft pulley provide and hence how it affects reliability.

I think Moose brings up some great points. There are tuners out there who do not make a good product, and there're shops out there who don't know what they are talking about... Regardless, I have read good things about Kleemann and the products they make. However, I still have not been able to find more information about their pulleys on www.kleemannusa.com, not even a picture. So Kleemann, can you help me out?

I think the C-Coupe will be a very popular car, especially for the younger crowd who are looking for more power.

Lets keep this thread going...

MOOSE... BTW I DONT WORK for UPSOLUTE either !!!
Just posting MY RESULTS on PRODUCTS THAT work!!
NOTE ....I spend LOTS of TIME/MONEY testing products for my PERSONAL USE WITHOUT SPONSORSHIP from ANYONE
So THAT OTHERS CAN ENJOY THE PRODUCTS WITHOUT The
cost /time of DYNO RESULTS ..........OK? THATS WHAT THIS IS ALL ABOUT
RIGHT?

It is great that you have made your knowledge and expertise to others. I will be consulting with you often after I take delivery...

CL203

The size of the SC belt drive is bounded by the proximity of the water pump pulley. It can only be so big. Strangely enough this is the size everyone arrives at, a 20% over drive of the compressor. If you look at a RENNTech, Carlsson etc pulley they all give the same relative increase in power- no small surprise as they are all doing the same thing.

Boost increase is at a nominal 2.5 psi- up from .5 bar to .65 bar. What other specs would you like? I am happy to provide them.

Kleemann

First of all, I think that it is great you guys are taking the time to talk with people in forums like this. I want to know if there are any draw back to changing pulleys in general. In addition, I would like to know the price range and just what I get for it.

thank you

There is always a price to pay when you want more power. Spinning the SC faster makes more boost but at the same time you can make the argument that the SC will wear out faster. A bearing will wear at the square of the speed you turn it, double the speed and you bring its failure point around 4 times as fast. Of course this scenario is fraught with variables- do you drive with high RPM's always or low? etc etc. If the SC had a lifespan of 100K miles perhaps you would be looking at 90K miles with the increase in speed- again there are too many variables to be exact.

The boost kit comes with a new crank pulley, a larger alternator pulley (no need to spin that device any faster), proper belt and insignias for the front wings that read KLEEMAN (black with silver lettering). The solid alloy pulley set up is $900 the factory crank version is $600.

Is this something I can install myself and I assume this will void my factory warranty so does Kleemann offer warranty?

Did you buy your C230 from Phil Smart? I bought some aftermarket parts from them a few years ago and they handled the install.

You really don't want to install the pulley yourself. IS your car an auto or 6 sp?
