replacing clutch '83 240D - PeachParts Mercedes-Benz Forum

biobenz240d · #1 08-31-2006, 08:20 PM

Hi, next week I will be replacing the clutch on my 83 240D. The release bearing is starting to make some noise , so after 258K mi. I think its about time for the works .(disc,pressure plate,release bearing ,pilot bearing) I have replaced clutches on various cars and trucks ,but not on a Benz. What I would like to know is there any tricks or anything out of the ordinary that I need to know? Better to ask first and feed off the vast knowledge of this forum than to make the job harder than it is . thanks in advance.

I hope someone replies. I'll be changing mine soon too. Same type symptoms.

I know a local guy that has 420K on his original clutch.

Cheers,

Bill

I just bought a 240 4 speed. I hope someone replies too because I plan on printing off this thread and saving it just in case...

One thing that I did last time that saved time later was too remove the clutch slave from the bell housing that will save you from bleeding the system, I used to disconnect the hydraulic line, easier at the time but more work later. Removing the linkage "clips" was a challenge the first time. Also be sure and mark the drive shaft in case its gets seperated, which can happen. Doing the clutch on these cars is not bad at all and feels so good when you drive it

dont forget to have the fw turned smooth. and replace the pilot and throw out bearing while in there and maybe the front seal on the tranny.

but i never would change a clutch just because of a little noise. i would wait til there is a functional problem. it might last a couple ofmore years without doing it.

but if you decide to go ahead, good luck

I haven't installed one yet, but I removed one from a junker and assisted a friend installing one and replaced my slave cylinder. My thoughts are that the mechanical bits are very straightforward. The hydraulics can be fiddly. The area around the slave cylinder is awkward to access and the chances of boogering the hydraulic line are somewhat high. I like Stevo's advice- if you can remove the slave from the bellhousing and keep the hydralics intact, do so. Bleeding can be a pain- bleeding from the right front wheel worked for me.

defiantely avoid breaking the hydraulic clutch system if you can.

they are a royal pain to bleed.

I replaced the hydraulic line in my 240 and it bled no problem. When I pulled the engine and transmission I separated the clutch line where the hard line from inside of the car and the line that runs over the tranny connect.

your clutch master may not have emptied. that is what is tough to get the air out of.

glad you had good luck.

many have not been so lucky.

Bleeding with the caliper didn't work for me. I just bled it like one would a normal brake caliper.

If you can't get an MB alignment tool, one from a mid 90's Chevy S10 works.

I use one from an old (80s) Volvo, same splines.

The throw out bearing has begun to make noise and is getting louder by the day. I bought my new clutch through Clutch Express in York PA. The kit includes pilot and release bearings , pressure plate ,disc and the clutch alignment tool all for 259$ and no shipping charge . I will get the fly wheel resurfaced and new bolts, I like the idea about not disconnecting the slave cylinder to eliminate having to bleed the system, no need to create a problem. I'll write back aftyer the job is done. Sept. 7 is the day I'll get started but it looks like rain. Driveway mechanic, the garage is full of biodiesel makin' stuff. later

t walgamuth · #13 09-06-2006, 11:25 PM

yep, sounds necessary.

good luck

Do you have the means to take pics during this process? I would love to see this before I ever have to do it. (like I'll ever get a 240D manual.....

)

I just did a new clutch when I put the turbo engine in my 240. It is very straight forward, just like any other clutch. I had both the engine and tranny out of the car. I was too cheap to buy an alignment tool, so I very lightly tightened down the pressure plate and used the whole transmission to align the clutch, then pulled the tranny off and tightened down the pressure plate bolts a quarter turn at a time. I disconnected the clutch line at the firewall, but it only took about 10 min to bleed it when I was finished. The PO told me that it the car had had recent clutch work and the throw out bearing looked new so I re-used it and did not have the flywheel resurfaced. I did use some 600 grit emery cloth to rough up the face of the flywheel and pressure plate though. I also put a new pilot bearing in too. Pry off the dust cover, remove the old one, grease the new one, tap it in place and tap the dust cover back on. It’s easy

Good Luck.
