Due to the severe engine damage caused by a broken valve, I must install a new/used engine. I have been told by several sources that I must replace my manual trans engine with another manual trans engine. If I don't do this I will be rewarded with a bad vibration from the drivtrain. What engines will bolt to my original manual trans? 220s, 230s, 250s, 280s? Are the flywheels from the previously mentioned engines interchangable? To eliminate the possible vibration, what components must be changed. Thanks for you assistance in this matter.

Good question, nobody here wants to give out the Mercedes Benz "cone of silence" (If you've ever watched "Get Smart" 1966 tv show with Don Adams) about parts interchanges. I've asked about swapping torque converters from a 190E 2.3 to 190E 2.6 to maybe gain an edge on performance in acceleration to no avail( no response). I have a close relationship with an old timer that knows parts interchange on the 1950s, 60s and 70s and early 80s stuff in his sleep, but not sure about the late 80s early 90s parts interchange. I the salvage yard specimans willbecome available soon and I hope to share thes " secrets with the Mercedes Shop faithful.

Always though to say everything that will work, but, here is a couple answers.

First, the problem that you are trying to avoid is the exchage of flywheels. The original flywheel of any of those motors were balanced with the crank and balancer as a unit. Any replacement flywheel had to be balanced to the originals imbalance. So what you want is a manual trans motor with its original flywheel.

Second the intermediate plate for your motor 180.947 has the same part number as a 130.920 motor (a 280S) MB # 615 011 02 45. This means that your trans will bolt to any of these engines 180, 108, 127, 129, 130, and maybe others. The only other concern is the spline pattern of the clutch. I'm not sure of whether they are directly convertable. There should be something that would work.

What about the bolt pattern on the crank? Is it possible to bolt my flywheel to an auto trans engine? How does one match the balance between the flywheel and flexplate? My engine choices are very limited if I can only use a manual trans engine. It would be nice to have more of a selection of engines to choose from.

One more question: If I remove the crank from an autotrans engine and balance the crank and flywheel, would that fix the imbalance problem?

The flywheel answers you have gotten are correct.
I have read that the way to do a flywheel
swap and retain the
original balance mating to the crank is to bolt
the new flywheel to the old ,back to back,
[ that puts them 180 out ], and balance them as a unit. Then, when you unbolt them , the
new one will be balanced [ actually-unbalanced] the same as the old.
Now when it is bolted back to the original crank, everything is balanced.
I have never done a flex plate /flywheel like this, but something to think over.
I will do some further checking.

Another member posted this: "...your trans will bolt to any of these engines 180, 108, 127, 129, 130, and maybe others."

Where can I find out what car models these engines are found in? Sorry to be such a MB neophyte, I have spent most of my time with BMWs.

Here is a list. There are many others out there, but over the years I have found this one to be the best. So I have downloaded it for anyone else interested in vintage Benz info. Go to:

i contacted a member of the unimog list and they said the 108, 114, and 130 engines have an independently balnced crank and flywheel. Is this true?
