Time to update this thread.
The new piston and gear assembly arrived from IBS - good service and the part was correct. I fitted it and ran the pump up. Unfortunately the pressure sensor for the low pressure/high pressure switchover seems to have been damaged during my endeavours. I need a working pump in the next week or so and I bit the bullet and ordered a new Analogue pump from Keiron at RIBshop. Good service as ever!
I REALLY wouldn't open one of these pumps unless it needs repair - the wiring is quite delicate and there are multiple PCBs kicking around in there. That said, I now have a pile of spare motors, connectors, plugs, etc. that all work - will serve as spares should I never need them (or anyone else on here)
