Lubrication
The B320 bevel gear operators have a sealed gear case, factory-lubricated with grease. No seal
can remain absolutely tight at all times. Therefore, it is not unusual to find a very small amount of
weeping around shaft seals — especially during long periods of idleness such as storage. Using
grease minimizes this condition as much as possible. If a small amount is weeping at start-up,
remove it with a clean cloth. Once the equipment is operating on a regular basis, the weeping should
stop.
5.1 Lubrication Inspection
Inspect the B320 bevel gear operators for correct lubrication prior to operating — particularly
following a storage period. We recommend the operators be checked during an overhaul program.
5.2 Factory Lubricant
The B320 series operator gear case is factory-lubricated with EP-0 lithium soap, mineral base grease,
suitable for temperatures from -20˚F (-29˚C) to 225˚F (107˚C).
a CAUTION: Do not mix lubricants of dissimilar bases.
