Most of the machinery in meat
packing plants is subjected to moisture and thus the conditions are such that rusting
occurs. For this reason gear
cases should be
tight to prevent
entry of water. Even so, the gear oils used should contain a rust
inhibitor....

Misalignment may be due to
wear of bearings and in extreme cases of failures it may be difficult to determine
whether a bearing or a gear failed first. In case of bearing failures, when
lubrication was at fault, either oil did not get to the bearing. Or the proper
oil was not used. Where a...

The most common reason for
leakage of oil from differential gear cases onto brakes is overfilling of the
housing. Under such conditions, the leakage will probably take place no matter
how effective packing may be. Use of quite low viscosity gear lubricants, for
example, SAE 75 grade in hot weather...
