MAINTENANCE 4.7 WHEN NECESSARY

4.7.2 SWING CIRCLE TOOTHING LUBRICATION
See illustration Z 20850
All teeth of the ring gear (3) must be completely covered with
grease.
If teeth are not completely covered with grease, they have to be
lubricated immediately with special adhesive spray grease, illust.
(Z 0148) or spread type adhesive grease as specified in the Parts
Catalog. The spread type grease can be applied, for example,
with a brush.
Observe the instructions on the grease container for correct use
of the lubricant.
OTICE
● If the machine is equipped with gear ring guard (6),
remove covers (7) for swing circle teeth inspection.
● If the automatic lubrication system of the swing circle-
teeth, is out of function for more than one shift, lubricate
manually (using spray grease) and remove the lube pin-
ion (5), to prevent serious damages.
● In order to ensure proper adherence of the lubricant,
clean and dry the ring gear prior lubrication.
In most cases it is sufficient to rotate the superstructure
several times for removing moisture from the gear teeth.
● Make sure that the multi-purpose grease of the swing cir-
cle bearing does not come in contact with the teeth of the
swing circle because this will diminish lubrication capa-
bility of the swing circle teeth lubricant.
If necessary remove excessive multi-purpose grease
from the swing circle above the dust seal ring.
