SWING CIRCLE TOOTHING LUBRICATION

See illustration Z 20850
All teeth of the gear ring (3) must be completely covered with
grease.
NOTICE
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
toothing fails to function for more than four operating
hours, bucket motion cut-off will occur. Repair the lubri-
cation system as soon as possible to prevent damage to
the gear ring, drive pinion (4) and lubrication pinion (5).
As an interim measure lubricate the toothing 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.
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.
