Thread: Air Clutch on ZF5-42 gearbox...

Hi guys.
As some of you know, Im putting a Cummins 6Bt and ZF 5-42 gearbox into my 101.... The box has this air clutch unit (pictured) on it. The engine is retaining its compressor and I have built in an air tank to my fuel tank system so the vehicle will have 'air on board'.. I'd like to retain the air clutch for two reasons... 1. SWMBO will be driving it, and 2. Why not! It'll be light as hell!!

My question. The larger line into it is for the fluid.. The smaller line is for the air. Is it safe to assume that if I connect the fluid line to the existing pedal and give the other line running air pressure, that the clutch will work and be light? (Given that there might be a master cylinder size issue).
Cheers for now.
