The original pump was fitted to a very well engineered 6 volt motor with an output shaft the same size as a deck motor shaft. The brushes lasted a couple of months.
The input side of a magnetic clutch fits on the end. This part fits over a fixed dome containing the other half of the clutch. There are no moving parts that go through seals.
The moyor went "pop" and stopped dead with an open circuit coil. I robbed another coil from another deck motor that had been converted to run a Meccano set.
I was not about to fully dismantle the whole assembly so the coil and lams were changed. The new coil has fewer lams so so it was packed with washers. The motor is not quite powerful enough to trip the magnetic clutch but it does the job. The chilled home brewed beer flows again.
In the photo is an original 6 volt pump that is easier to see. From left to right there is the grey manifold, next is the brown gear pump, after that is the silver magnetic clutch and finally the 6 volt motor.
