Simple, don't lug the engine by running at such a low RPM. :)

With the stock turbo the torque peak is around 2800rpm. Even with a VNT the torque peak is 2000-2200rpm.

vibration causes
 

I know on some of the older Mercedes the crank and the flywheel were balanced as a unit. I have balanced flywheels before. You need a lot of special equipment, so it would need to be done at a shop that works on driveshafts and such.

What I am saying here is that perhaps the problem with the vibration is coming from the change over to the 240D manual shift flywheel from the 300D auto shift flywheel.

I know what type of job it would be to tear down the car to do this, but you might consider trying it out on a future conversion, or if anyone else here does one they could try it out and report their findings.

If you have the equipment it takes about 10 minutes to balance a flywheel/ring gear combo so it should not cost that much if the flywheel is out of the engine.

I just picked up a 300D with a bad trans and need to get it drivable ASAP to do some prechamber tests. I don't want to spend time on the automatic and the 5 speed bell housing project is not far enough along for me to wait.

Do you have a "kit" available? Please PM me with .
details.

Side note: I have been out of town and will get an idea of the casting pore cost this week.

thanks

any kits left where are you located?

how about the drive shaft, what do I need to do for a driveshaft in a126?

Hey lutztd, do you still have a kit available? what was your price for everything? Including the drive shaft? This would be for an SD. I am very interested! My poor benz is on blocks waiting for a manual.

sorry no, I have about 80% of whats needed. I will watch for a car, but the kit I have is missing components and I want to offer a complete kit rather than piecemeal. when I posted I knew where a car was but when I went to collect some of the parts the shifter was bad and the trans was full of muudy gunk so I assumed the rest was in equal state of repair and I left it. I will post again when I have a full kit.

I have a spare tranny I just pulled out of a W123 that works fine. $ 175 and it's all yours. I'm in the metro Detroit area. Just picked up two more cars to do surgery on, so you can send me a private e-mail if you want the trans. I'll have more coming in March.

I was going to put a 240d and AT in a 170D but that's too much work, easier to pout the stock OM636 therein.

I may be interested in a kit. I just bought a 82 300D and the tranny is slipping. I'm going change the fluid and filter and try to get it working properly, but would prefer a stick anyways.

I live in South Dakota, and there are very few Mercedes cars in the area, much less any in the bone yards.
