I have an om606.962 pulled from a '99 E300 TD almost ready to go into a W124.130. The 124 has a 5-speed 717.430 gearbox and an om603.912 NA engine. From what I have read, I am reasonably confident the 606 will bolt up to the transmission. What I'm less sure of is the suitability of the flywheel and clutch in the 124. Can anybody verify whether the 606 will work with the flywheel and clutch in the 124, or am I going to have compatibility issues?

fwiw, single mass fw's and 717.4xx boxes are not good friends. been in a few conversions and thought them to be rather crude compared to the original but tired m103/4 and 722.3 autoboxes This is a more common conversion for a w460/461 G and they are god-awful rattling things to drive, so a G owner wouldn't know what he's missing really. Wink
The 717.4 box is not a 'great' unit, and in a w124 I would honestly go for a 722.6 and Ole's controller.
Even the 716.6xx 6 speed manuals are not particularly spectacular boxes behind the petrol 6 cyls (eg:m104), and the 716.6xx ratios are not entirely suitable/useable, certainly a 3.27 LSD would be the "preferred" option for a 6 speed with 0.83 6th in a w124, and if you want to persist with the 5 speed, then 3.07 is about as tall as is practicable. Never mind all the additional stuffing around to make the 6 speed fit.
The autobox is far smoother and much kinder to the drivetrain - no shock loading and no pulse from the combustion cycle.

The downside to the manual boxes is the cost and availability of replacement bearings - given these boxes are all getting rather old and tired, synchros are not always available, and are typically quite worn, poor maintenance by some owners see incorrect fluid used, which hurts the box, especially if a GL5 gear oil was used in servicing (hopefully not - $$$$).

It would be wise to find out all the history of the vehicle/transmission before you plough ahead with any swap, but the easiest bit is simply taking the bits off the 603 and bolting them up to the 606. ***should be all AOK, if serviceable.
