m110 flywheel idea
m110 flywheel idea
the idea:
get an M110 flywheel and clutch (bigger, heavier duty clutch but less weight)
machine a steel ring to fit on top of the outer lip of the M110 pressure plate to give it more rotational mass.
pros:
quite a few G-wagen guys are swapping out their M110's for 617s. most came stock with 4-speed manual trannies but they are switching over to the sedan automatic because of the high cost and scarcity of G- clutch parts. so finding a way to reuse the M110 clutch seems pretty cool to me.
cons:
It seems pretty straight forward but machining the ring may not be that easy. it would need a pretty big lathe. Would have to figure out where to source the chunk of iron too. maybe a cut from a pipe of the right diameter that is then milled to spec.

A lightbulb went off over on one of the G-wagen sites and I thought I'd run the idea by you guys in case it's been done or there's known reasons not to do it.

The 617 FW weighs 38lbs and the 616 about 10lbs less.
Also, as seen in the second picture, if you make a ring it will have to clear the starter nose.

Why not use a 240D flywheel and M110 clutch? It will take a LOT of weight to get it even close to a 240D's mass.

Whats the point of the M110 clutch if the diameter is the same? Are you sure its not just the clamping pressure of the pressure plate? I have the 23CM gwagen setup.

I was assuming the M110 clutch was bigger but I haven't measured yet (I have one but it's not separated from the engine yet).
But the more I think of it, the more it seems like an iffy idea.

AFAIK there are only 2 sizes during those years, 21cm and 23cm. I have the 23cm setup which is great for low rpm higher torque operations (getting up on the ramps has never been easier). Otherwise I would just stick with the 21cm setup, there are a variety of pressure disks with different pressures which should be more than adequate for anything you can throw at it.
