Looking for Clutch Line Replacement Help - PeachParts Mercedes-Benz Forum

teddyd49 · #1 11-12-2009, 05:29 PM

Have been informed by mechanic that the reason my clutch (installed last February) has burned out and requires replacement is because the clutch line that runs between the clutch master and slave is frayed/defective and this has caused the early death of the replacement clutch. I have a 1982 MB 240D sedan.

Have been looking at parts websites and cannot seem to find this part. My mechanic has contacted MB directly and it will be several weeks before they acquire a replacment part.

Any thoughts on where I might find this part at a reasonable price in a more timely fashion?????

Thanks.

I think I may have what you're looking for. The rubber line is attached to the piping. You'll have to bend the piping back, but it doesn't leak. $20 + shipping, you do paypal, I can have it out by tomorrow.

Something is odd about that diagnosis in my opinion. Why would a bad clutch line cause failure of a clutch? I could see where it might hinder the action of the clutch requiring multiple pumps on the clutch pedal to get the clutch to function but I don't see any connection between the line and either the clutch disc or the pressure plate. Perhaps other people can see the connection, but I would be suspicious.

Well, I'm with Kerry on this one until we can get more info. Is the line leaking if it is frayed? What exactly does your mechanic mean when he says that the clutch is "burnt out"?

Actually, let's back up - tell us what symptoms you were experiencing that made you take the car into the shop. Do you know which parts you had replaced last Feb?

If you have more info that would be helpful in diagnosing the problem. You certainly don't want a leaky line, but that shouldn't cause premature failure of your clutch.

Ha - Sorry JE. Doesn't mean it won't be needed, you might still have a sale on your hands.

So, in other words, don't blame me for installing your clutch backwards and inside out, there was this obscure , mechanical defect....

Did he use a new clutch or were you trying to drag with the ricers? This diagnosis makes no sense at this point.

Using the clutch peddle for a foot rest will apply pressure and cause slipping of the clutch.

Also if there is pressure on the master cyl from being out of adjustment in the linkage, will also cause a problem.
the only adjustment I see on the MB is the rod going into the master cylinder, or the ecentric bushing at the master. there are 2 rod lengths I know of.

Looking at the parts, there are the early and the later throw out bearing and master cylinder depending on chassis mfg date.

between the master and the slave cylinder is the 2 metal supply lines with the short rubber hose connecting the 2 together.
I bought the section with the rubber hose fron the dealer, around $70.
comes as a straight piece and has to be formed to fit. over the transmisson to the Slave. just go easy on the bends, I used my thumbs and make sure the pipe is warm.

I would definitely get a second opinion. If the line is frayed (and I assume leaking) then your clutch probably needs to be bled. I can't see any relationship between a frayed line and and the clutch disks wearing out prematurely. I would also request the old clutch if you have them replace it.

But, as others have stated, the more information you can provide, the more accurate the answer will be.

I just dont see any relation between the two.

Good luck!

I am at a distinct DISADVANTAGE as I am not mechanically astute when it comes to this car. The mechanic is a pretty good one. I was suspicious of the reason for the new clutch burning out, and I suppose he had to come up with SOME reason for this happening after only 10 months of wear.

The clutch began to slip between third and fourth gears several weeks ago.....would accelerate without actually catching the higher gear. It then started to do same thing between second and third gear, especially on steep hill climbs. It finally started to fail completely late last week and I had to have the car towed to the mechanic from the road.

In the final analysis, I am a captive prisoner to this fellow for the time being and need this part to get the car out of the garage. He has ordered new part directly from MB but don't know when it will be available.

JEBALLES: If it is going to take longer than arrival by Tuesday, I will take you up on your offer for the used part (although I am adverse to putting a used part into the car as this might just cause more problems). I will contact you on Tuesday AM if I need the part.

I asked the mechanic to check all the linkages to insure that something other than the clutch was NOT THE PROBLEM so that I don't have to replace the new clutch in another 10 months. He did this and came up with this clutch line ISSUE that he has identified. Said it would act like I was riding the clutch over the 10-month span and that THIS was the cause for the failure of the new OEM replacement part installed last February.

Thanks for your input. Will advise you of progress, if any, on this front.

.

Makes no sense to me at all. A leaking line will reduce pressure on the slave cylinder thereby not allowing clutch riding. Something is awry with this diagnosis. I don't know if it's possible to set up this kind of MB clutch with a permanent load on the activating rod coming from the slave cylinder. This might cause the problem but again I doubt it.
Did you see the old parts when the mechanic replaced the clutch originally? What were your symptoms that caused you to replace the clutch originally?

Pure unadulterated BS.

I did not see the new or used part installed in the car when it was replaced earlier last year.

Am at a loss as to what might cause this to happen. This mechanic is MB certified and has been working on (specializing) on MB/Audi/BMW cars old and new for about 30 years in the area.

The same symptoms occurred when the clutch first started to fail as when it failed the second time. I had had this car for about 7 years without any clutch problems until last year.

There must be something going on inside the set up of the clutch to make this happen. He orders new (not reconditioned) parts that are OEM in almost all instances...and charges top dollar for same.

rs899: Why is this diagnosis unadulterated BS? And do you have a fix that might help out in this issue? Thanks.
