REPAIR INSTRUCTION
Disassembly
Refer to the sectional drawing and spare parts list when disassembling and reassembling. The
vanes should be changed in good time. They are considered worn if their width is less
than 7 mm, see Fig. 6
H new 8 mm
H min 7 mm
Loosen screws item 21, pull out centering cover item 7 and inner motor parts. Pull end plates
Items 40+48 with bearings items 41+47 and spacers Items 42+48 off the rotor item 45. Take off
cylinder bushing item 43 and remove vanes item 38 from the rotor slots. Replace vanes when
necessary.
Reassembly
Remove any oil and resin residue from the rotor slots before reassembly. The new vanes item 38
should fit easily into the slots. Basically, re-assembly is done in reverse order.
Caution!
If the bearings items 41+47 have been replaced, ensure correct spacing. If necessary, use new
spacers items 42+ 48 and adjust the clearance Fig 7. The spacer should be fitted 0.04 – 0.05 mm
in front of the end plate. To get the right clearance, it is necessary to press the inner bearing ring
backlash-free towards the bushing item 4 respectively washer item 19. The chamfered edges of
the spacers items 42 and 48 should point towards the plane surface of the rotor.
