Hi, Looking for a flywheel that will work for a manual conversion on an 717.411 transmission for a late model W124 e320 that will have the sensor pickups. I believe it is a single mass flywheel that works with this combo.

Alternatively, looking for an entire conversion kit that contains everything needed for the conversion, preferably with the larger 717.3_ _ transmission from the larger cars. Thanks.

Believe you will find it very difficult to find a single mass FW for M104 with HFM (?) injection (94 e320). M104 manuals in the rest of the world had dual-mass FW. The M103 single mass will work with modification.

Dual mass FW work only with the DM manual transmission (shorter input shaft), single mass FW works with SM trans (longer input shaft).

For single mass information, search at 190-rev.net Choices are cu$tom, welding modification, or possibly as simple as mounting a trigger magnet taken from an automatic flex plate (which will be my first path when pending conversion gets under way).

Enjoy, it will become a completely different car. Put it in 5th and its got legs. While you're at it think about having the shifter modified for shorter throw (see vendor forum on 190rev.net).

You will need to go with a dual-mass flywheel for short input shaft transmission. This type of transmission requires the pilot bearing to sit within the flywheel.

Every custom solution that you might find on forums such as 190rev applies to long input shaft transmissions. There are all kind of lightweight flywheels and adapter plates that bolt onto inline 6 cylinder flexplate (to keep the 3x pickup plates in place) but i could not find any ready solution for a short input shaft transmission.

I saw on UK ebay conversion kits from DM to single-mass flywheels for newer diesel cars. Those don't have the signal pickup plates, so you'll have to come up with a solution for that.

If you want to keep it within stock HP numbers, DM flywheel is not that bad beside costs when you need to replace it.
If you want to go single-mass and stay with mercedes brand, get the 190e-16v dogleg or an early 5 speed from an m103 (in US, 300E from 86 or 88). You can mix these with regular m103 flywheel or custom flywheels for long shaft transmissions.
