Disassembly and Reassembly
of the Electric Motor
Before starting work, always disconnect the motor from the mains. Pull
the mains plug.
Required tools:
Allan keys size 2,5, size 3 size 5 and size 6. Possibly a puller for the cou-
pling.
Place the pump on its front side.
Unscrew the four
non-recessed
hex. socket screws (11/7).
Remove the intermediate flange (11/8) together with the electric motor
(11/6).
Remove the gasket (11/1).
Remove the handle (11/2).
Loosen the threaded pin (11/4) and pull the coupling (11/3) with the blade
wheel off the motor shaft.
Unscrew the hex. socket screws (11/9).
Remove the electric motor (11/6) (and the adapter flange (11/5) in the case
of the USA motors).
Clean all parts and check that they are in perfect condition; if not, replace
them with new parts.
Reassemble in the reverse order.
In the case of 60 Hz motors (USA versions) with adapter flange the cou-
pling must not be pushed on to the shaft right up to the stop. On the
other hand if it is not pushed on far enough the pump module may be
damaged during operation. Push the coupling on in such a way that the
distance between the front end of the coupling (11/3) and front side of the
adapter flange (11/5) amounts to 41.3 ± 0.8 mm (1 5/8 ± 1/32 inch) (see
Fig. 11). The adapter flange (11/5) is screwed to the motor flange with
four additional screws.
