Re-assembly
Before starting reassembly check all parts for wear and replace them if necessary. Wear
parts are in particular vanes, radial shaft seals, o-rings and end plates.
Motor
Reassembly is done essentially in reverse order than disassembly. Remove any oil and resin
residue from the rotor slots. The vanes should fit easily into the slots. When assembling the
inner motor parts, ensure correct spacing. The axial play between rotor item 13 and end plates
items 7 and 15 should be 0.04 mm per side. The chamfered edges of the spacers items 10 and
18 should point towards the centre of the rotor.
Direction of rotation of motor: counter-clockwise looking at driven side (shaft butt / pinion).
Gearbox
After installing new radial shaft seals into gearbox head item 401 intermediate washer item
422 and output shaft item 402 - pre-assembled with bearing item 420 - have to be pushed-in
and completed. If countershaft assembly was disassembled and re-assembled the nut item 410
has to be tightened with a torque wrench to 35 Nm for adjusting the sliding clutch.
At installing the control lever item 431 take care that positioning is correct. After inserting
the countershaft assembly pour in approx. 0.2 litres grease/ lubricating oil and bolt the gearbox
head and intermediate housing.
Subsequently assembly of the main components can be done.
After completion of re-assembly make functional gauging. If the motor does not run (rotor
jams), light tapping on the motor housing is helpful to bring the rotor into a free-wheel position.
Grease:
Use sodium saponified semi-fluid grease GP 000 M-30 DIN 51502, approx. 100g.
