Hey guys

I posted last time about, a horrible noise coming from the back, I got the problem resolved after it was a bad right rear wheel bearing.

But this morning I went for cofee and just before I got home, I could not get the car into any gear while driving, the only way I can get it into gear is when the car is not running. I then switch it on and the car would stay in a gear and just move, and that is the way I got it home.

I tried searching the forums, but most of the problems is only for automatic cars.

Anyone, that can shed some light on my situation?

I absolutely adore this car and I am proud driving it.

Hi there

It is an manual, and busy taking the transmission out but have a problem, everything is loose but I am not sure how to take apart the top part where the gear lever is connected to the transmission any one have an idea.

thx for the reply's.

You likely have a clutch hydraulic system failure. Master or slave cylinder leaking or a hole in the hydraulic pipework.

Yeah, I would not pull the tranny,
What could you possibly hope to accomplish unless you have a spare on hand?
Like Glyn said, check the hydraulics for leaks, bleed it just for fun,
and also check the oil level in the tranny.
Maybe you lost all your oil?

Glyn M Ruck

You need to pull the tranny to check the clutch. The slave cylinder is inside the bell housing on a Merc.

Thx for the reply's guys, wouldn't I see fluid coming out somewhere? I also checked all the reservoirs and it looks like there is no leakage? Or am I in the wrong?

warm regards

Glyn M Ruck

Yes you should see a leak somewhere. But the clutch is what engages or disengages drive so the problem has to be there. You might have a pressure plate failure of some sort or a piece of friction material has come loose on the clutch plate & jammed things.

Danke Glyn!

Will give an update as soon as I know what is happening inside, going to drop the transmission tonight.

Hi Stephan,
We were correct - clutch plate & pressure plate damaged.

Re your PM

FYI flywheel - 47. Flex plate also shown for Automatic. Flywheel is sold as a single part.

Hi guys

Thx Glyn you are spot on as usual, here is pictures of what magic little parts we found inside the tranny.

Is taking the clutch plate in to a company that only deals with clutches, maybe they will refurbish it, although will see what happens.

Thx for the diagram, but what I cant figure out is, what number is the part on the diagram where the arrow is pointing to?

Warm Regards, appreciate all the help.

Glyn M Ruck

Refurbishing is possible but I would go new on a Benz.

The arrow is pointing to the flyweel clutch facing. All part of the flywheel assembly with built in damper like a Porsche. You must just clean that facing with sandpaper. Your alternative is a new flywheel - expensive & not necessary from what I see in the pic.

irrogue

The price for a new clutch is R2500 / $ 296.52 , and the fly wheel is $533.7, in South Africa

I will be buying a new clutch, and leave the refurbish idea.

Will give an update soon.

Ok so last night I was underneath the car, and checking everything out, when I noticed a Oil leak in a small metal box.

Here is the picture http://imgur.com/PLHYS

I saw there is a sticker with a part number on it.

It looks like it is A 271 230 0965

Any one know what it might be?

Warm Regards

I'm having difficulty with orientation. If that is looking straight up the back of the engine it is the vacuum pump.

Nothing to do with your present problem & repairable from the top.

Tri-Star

I knew it was the clutch the minute I read it. I burnt out several on my previously owned WRX.

Glyn M Ruck

Stephan,
While you have things open please check the condition of the thrust bearing.

C230 Sport Coup

Ooooo the flywheel is toast? Don't people just usually turn those ie take to a machine shop, and only if it's badly scored from rivets? Or is it the pressure plate that $500 + ?
Yikes!

Glyn M Ruck

Like Porsche you can't skim these composite flywheels - machines can't get there. That flywheel will clean up with sanding. As I've said to Stephan in PM as long as there are no high spots or surface cracks it will be OK. Rotary marking like a brake disc can be tolerated as long as not chronic.

A Porsche clutch will cost you $4800 these days for parts alone due to this design.

Hi Guys!

Glyn, I'm am not sure at the moment but don't we get the thrust bearing with the clutch kit or is that a separate part to buy?

There was at least no cracks or anything on the fly-wheel, or any damage I can see just very dirty.

I did not have chance to do anything yesterday, but will utilize the weekend to check if I can clean it up a bit.

Anyone know the torque settings for where the pressure plate bolts to?

One more thing what does that vacuum pump do?

Warm Regards

Stephan

Glyn M Ruck

You are going to have to ask if the thrust bearing is part of the kit.

From memory pressure plate torque settings are about 33 lb ft or 45 Nm. They should be on the instruction Benz supply with most spares. Remember to Cross Torque the bolts.

The vacuum pump provides controlled vacuum on some models for brake booster & vacuum operated headlight controls etc.

Hey guys!

I got this issue resolved at last, first we got the wrong clutch and later learned in the LUK book it uses the same clutch as the 230 sedan.

I checked the thrust bearing out and it looked fine, so it wasn't replaced.

But man it was ALOT of work wriggling the bell housing onto the engine, the biggest issue is that you work above your head and that is extremely tiring.

If I had one of these http://www.rolloverjigs.com imagine how easy it would have been.

Also did a full service, and tightened the bolts on the vacuum pump, that resolved the oil leaking issue.

Also bought new clutch bolts, as the old ones was bent and broken on the heads of the bolts.

It is driving like a REAL mercedes again, and so proud.

Thx for all the help Glyn and all the other guys.

One more question.

I did check the forum and mailed supershyguy, but I dont get any reply for the brabus rep lip I am really interested in that specific lip.

Warm Regards

Stephan
