Disassemble and reassemble the gearbox
Attention:
The gearbox has oil lubrication
Disassemble (see fig. 19)
1. Remove the coupling (50) from the shaft (35). Remove
the screws (52) and remove the gearbox cover (51).
2 Remove the filler plug (44) and gasket (45)
3. Stand the gearbox upright and drain the oil into a suitable
container.
4. Loosen the set screw (47) and remove the steel ball
(46). Unscrew the adjuster (42).
5. Remove the cup spring (41).
6
.
Remove the locking screw (38) and remove the
retention pin (39).
7
.
Remove the circlip (37), bearing plate (33) and bearing
( 36). Remove circlip (34) and press the bearing (36)
out of the bearing plate (33). Remove the circlip (37)
from the gearbox shaft (35).
8. Remove brake disks (28) and gear ring (29).
9. Remove planet gears (32), needle bearing (31), thrust
washer ( 30), planetary gear shaft (27) and pinion gear
(26). Remove gearbox shaft ( 35).
10. Remove set screw (17).
11. The remaining parts within the housing (1) can be
removed from the flange side. It is helpful to tap the
edge of the body in an axial direction (flange end) with
a wooden or rubber hammer to loosen the bearing end
plate (15).
12. Remove the planet gears (25), needle bearings (24)
and thrust washers (23) from the planet carrier (22).
13. Remove planet carrier ( 22) and pinion (21) from the
plant carrier (3).
14. Remove bearing (20) and bearing plate (15) from the
planet carrier (3).
15. Remove the circlip (11) from the planet carrier (3) and
press out the planet wheel shaft ( 10).
16. Remove planet wheels (7), needle bearings (8), thrust
washers (6) and spacer ring (9).
17. Remove bearing (5) and seal (4).
Clean and inspect all parts. Replace all worn or damaged
parts and the gearbox is ready for reassemble.
Expendable parts are:
thrust washers (6, 23, 30), needle bearings (8, 24,
31), O-Rings and seals (4, 16, 18, 43) and the seal (45)
Reassemble
Reassemble the gearbox in the reverse order according to
the sectional drawing (see fig. 19).
Take great care to fit the planet gears (7) with needle
bearings (8) of the same sort, thrust washers (6) and spacer
washers (9) properly into the planet carrier (3).
The brake disks either side of the gear ring (28) must be
steeped in oil (soak for one hour in oil) before they are fitted.
The exact adjustment of the overload device is first possible
when the unit is completely reassembled. A preliminary
adjustment is made by compressing the cup springs (41)
with the adjuster (42). Once the final adjustment has been
made secure the adjustment with the set screw (47) and
steel ball (46).
Fill the gearbox with around 0,3l gearbox oil (CLP 460
according to DIN 51547).
Replace plug (44) and gasket (45).
