Disassembly and Re-assembly
Disassembly and re-assembly should only be performed with assistance of the exploded views
and sectional drawings.
Disassembly
Motor
Remove gearbox neck item 2 from motor housing item 1 while watching out for the planetary
wheel item 15, the washers item 14 and the bearing needles item16. Then knock out the inner
motor parts by slightly tapping the motor housing item 1 on a wooden block.
Disassemble motor. Check vanes item 50 for wear.
Governor
Remove segment bridge item 27 from rotor shaft item 7 (left-hand thread), while watching out for
the governor dials. Check the governor parts for wear.
Angular Drive
Remove output unit housing item 3 from gearbox neck item 2 (watching out for the end plates).
Unscrew fillister-head screws item 66 and pull the planet carrier item 12 (by means of M12 screw)
carefully from bevel-gear pinion item 17. Than remove feather key item 53 and pull out bevel-gear
pinion of the gearbox neck item 2. Unscrew sleeve item 19 and end cover item 24 and remove
bevel gear item 22 from adapter sleeve item 21. After removing feather key item 54, pull out
adapter sleeve item 21 of output housing item 3.
Lubricator
The lubricator adjustment screw item Pos. 32.2 should be readjusted only, if the oil throughput rate
no longer meets the requirements. For adding oil just unscrew the plug item 32.4. To adjust the
lubricator under operating pressure turn regulating screw item 32.2 counter-clockwise to open it
until air bubbles slightly drift upwards through the oil.
Re-assembly
Re-assembly is performed essentially in the reverse order. Ensure correct spacing. The axial play
between rotor item 6 and end plates items 8 and 9 should be 0.04 mm per side. The chamfered
edges of spacers items 52 and 55 should point towards to centre of the rotor.
