Has anybody done this conversion? Using the standard five speed from a 190 or 300d with stick?

If you take Larry off of ignore for a few days, you'll see that he is selling his 1988 300 E 5-speed.

Here is the OP:

Quote:

I have two Euro 240D parts cars, a 1980 and a 1984, both with four speed manual transmissions.

I also have a running 1988 300E manual transmission car. It is registered and inspected, but I have finally given up on it for a driver.

The 1980 is without engine, but transmission and aftermarket a/c are intact in car. Steering box and most of engine compartment items gone. Front suspension in place with no springs, but is worn out stuff from the 84. Lots of decent sheet metal, but the car has been repainted with enamel. Has a nice set of euro bumpers.

The 1984 has the engine from the 1980, and it is worn out. Original four speed manual in car and everything intact, but has not run in years. Another parts car, primarily for the transmission, but lots of other items such as early round Euro lights and the vacuum dial for raising and lowering lights. Rear euro bumper is FUBAR.

1988 300E has 333,000 miles. Intermiitently will not idle. Leaking oil from headgasket on passenger side. One of the 300 or so manual transmission 300E's US equipped in MY88. Nice Panasonic radio. Nice palamino leather interior with very minor wear on drivers seat. A/C was making ice cold air until the belt tensioner laid down. Now it trips the rotation sensor circuit. It is rust free with minor damage on the right front door and fender. Paint has seen better days. If I were to come across a Cherry, low mileage car, I would put the manual transmission in it and have a parts car, but I just have gotten my money's worth from the car. Oh yes, it has a 500E rear sway bar. It also has a set of Michelins, perfectly balanced and very low mileage. I might part the car out, but I would rather sell it to the right person that realizes the value it has.

PM me with any interest you might have. I need to just get these cars off the premises.

The cars are located in NE Texas 100 miles or so NE of Dallas. You can legally and reliably drive the 300E home, but you'll have to bring a trailer and winch for the 123 cars.

I am attaching what few pictures I have. They do not reflect the poor condition of the paint. You might can see the minor deer damage in the right front door.

I am looking for offers on these parts cars.

...interested in this car, are you?

Maybe...

Yes, I have done it. I used the 5 speed from an '86 190E 2.3 (717.411). All bolt in, except for front driveshaft (33 inches). No problems with the stock 8.5 inch clutch after 20k miles.

Kept the stock 2.87 rear diff, a bit slower off the line but it cruises at 2000 rpm at 65 mph. 3000 rpm at 100 mph. If it had enough power it could do over 160 mph. Average about 40-41 mpg highway at 70mph and about 36-38 mixed. The gaps between gears are a bit large but it can easily be managed, especially if you are used to a 240D.....

Being able to wind this motor up to 4500+ rpm with no torque converter losses puts a smile on my face every time.

Now that's what I'm talking about!

Thanks very much! I will journey to Chicago to look at it with a cheerful mind!

I have an 87 300D that I just finished installing a 5spd into from a 92 190e 2.6. 2000rpm @ 70mph and 40mpg is a beautiful thing. I have a second 5spd kit in a box looking for a good home. Recently came across 97 E300 diesel non turbo. I wonder if the w201/w124 shifter and pedals bolt into the w210 body. Now that would be an interestin car.

I used the flywheel from the 190E. I had it resurfaced, but didn't worry about balance. It's only from a 4 cylinder so it seems many here would say it is too light, I haven't had any trouble with vibration.

That six cylinder is just so smooth.

I did go up today and put a deposit on Matt's car. It is a really sweet running car with working ac, a nice interior and a decent body, just as he described. It will require paint to look good and some rust repair. He has done a lot of good things to it and is ready to make a change.

That would be cool except for the stinking electronics

123 = no engine electronics, mechanical engine controls
124/201 = EDS only, which is minimal electronics, it can be bypassed and car will still run (just not idle as smoothly)
210 = full drive by wire, CAN bus runs everything. Transmission is electronically controlled. You still have an indirect injection pump but the computer decides how far to pull the rack when you push the pedal.

I imagine that the engine computer will not react well to not being able to communicate with the now missing transmission computer. Every system ties together in that car.

Not to mention that the 124 and 210 bodies are totally different. I have one of each in my garage and it is apples and oranges.

TheDon · #12 06-04-2013, 01:38 PM

I do see you running into clutch issues. Mainly the ability of the clutch to not slip under wot

t walgamuth · #13 06-04-2013, 02:07 PM

Well, since it has less torque than the 617 turbo and many of us have had good luck with that setup, I imagine this will work too. Of course if the clutch on the 190 is smaller than on the 240...?

Well, yeah a straight six should be smoother than a four or five....so the weight may not be needed as it is on the 617.

There are 3 clutch options depending on which flywheel you have. 8.5", 9.0" and 9.5". The early 190s had a 8.5" single mass clutch and that one has been known to slip behind a turbo OM603. I have a 9" dual mass and it doesn't slip ever. the 9" dual mass can also accommodate a 9.5" clutch disk which was a used on the R129 M104 and E320. While I am happy with the 9" at this point, I will be getting a 9.5" clutch when it comes time to replace.

BTW single mass and dual factory flywheels are not interchangeable. The gearbox input shaft length is specific to the flywheel type.
