I have this 2004 ram 3500 2wd with a 12v cummins swapped in. The NV5600 is beside the FSO6406a gearbox sitting in my garage floor. I'm convinced i need the sae2 fuller clutch housing to match the 12v cummins flywheel housing, and the 14" flywheel and clutch to match the 1.75 input shaft as well. Where i'm getting lost is the clutch actuation: the dodge has the push type slave cylinder and the fuller is a pull type mechanism. I'm open to any suggestions/recommendations.

You need a 6BT-specific SAE2 flywheel housing, matching starter, and the bellhousing for the Fuller.

It would be a stock setup from a mid-late 90's Freightliner FL60/70.

u2slow -
I have the Flywheel housing for the cummins
I have sources for the fuller bell housing(with mechanical pull style clutch) and the 14" clutch to match the 1.75 input shaft.
The FSO6406a came from a salvage yard FL70.

My issue is the operation of the fuller mechanical pull type clutch in a truck that came with push type hydraulic clutch setup. I do not have a preference as to going mechanical or hydraulic, i'm just learning these legos.

Sorry, not much help there.

Just makin sure you had pieces that bolted together.

Ok,dumb question, was the FL70 a hydraulic clutch?

If so, I would adapt the FL70 slave to the Cummins master, and run the whole FL70 setup.

the fuller clutch housing is a mechanical pull style clutch. Pull style hydraulic slave cylinders do not exist "as i understand it" because that's not how fluid pressure works.
