3.Remove circlip (8640) from the rear end of the shaft.

4.Un-tighten countersunk screws (1540) from the front end and remove them.

Remark: The pump shaft (0702) can be rotated to allow access to these screws. Be care- ful that the spanner does not damage the magnets in the outer magnectic rotor (8320).

5.Drive out the complete pump shaft to the front by tapping with a plastic hammer on the pump shaft (0702).

4.2.5Disassembly of outer magnetic rotor

1.Un-tighten cap head screws (8610) crosswise and remove them.

2.Use threaded holes in the flange of the pump shaft to remove the outer magnetic rotor (8320).

Removal of ball bearings

1.Remove circlips (1450) and support ring (1460) from the pump shaft (0702).

2.Remove the bearing (1440) from

the shaft using a ball-bearing extractor.

3.Remove the bearing cover (1430) from the pump shaft (0702).

4.Remove both circlips (8620) from

the bearing bracket (1400) to the front.

5.Drive out ball bearing (1440)

from the bearing bracket (1400) to the rear.
