Ian - thanks again.
Mounting it shouldn't be too difficult on mine: the pulley on the headsock gearbox is under the changewheels cover & the shaft it drives protrudes around 3.5". The pulley itself is installed 'boss outwards' & hides the bearing cover. The bearing cover contains an oilseal & is a flange fit with 4 bolts so either a new bearing cover with mounts for the clutch stator/coil or an adaptor to fit the stator to the existing bearing cover will be easy options. The shaft protrusion will, I hope, be long enough to accept the driven & driving elements.
Whilst Googling electric clutches I've found them used on tractor PTO's and on the cutter drives of lawn tractors - all of similar size to the aircon pump clutch.
Yours looks to be a nice, handy, setup.
Regards
