I didn't get any assistance on my earlier question on how to remove the rear housing (clear plastic moulding) behind the motor, but managed to do it.
The motor works fine, but had been twisting on its mountings and had pulled one of the supply cables off the connector to one of the field coils. The two supply cables were TIGHTLY WOUND ROUND the spring which is compressed between the back of the centre of the motor and the housing to form the back motor mounting The pull might have broken one of the cables and, in this unearthed ("double insulated"!!) appliance, caused the steel case to go live (!!!). Instead, the result was far less worrying, but its cause does need eliminating.
Why did this happen? Because the fins moulded into the inside of the housing, which interlock with fins on the back of the motor to prevent this twisting round on its axially central front and rear central mounting points, had failed.
Why this failure? Because this motor, which is a replacement fitted about 15 years ago, is nearly 50% more powerful (1,150 Watts) than the original (770 Watts). This gave a huge improvement in sucton, but no doubt the housing fins had been gradually bending and eventually breaking off ever since the change. Finally, enough of them broke to allow the motor to turn round several times - with the results already described.
I am in a quandary - for two reasons - and seek guidance:-
1. I can't find a new replacement housing, though it is rumoured that it can be got. Does anyone know from WHERE?
2. Even if I could find one, sooner or later the very high starting torque reaction will again overstress the housing fins. Possibly this might take another 15 years, by when this cleaner is most unlikely to be still in use! However, if a new housing is fitted, it would make sense to fit a SOFT START module - to stop the motor jumping up to full revs so quickly and exerting such a shock loading on those fins.
Any ideas? There is not exactly masses of space inside, as anyone who has done serious servicing on the series of Electrolux cylinder cleaners to which ours belongs will know.
