TYPICAL
INSTALLATION

The 83167 Pump is used as the

pumping unit for a centralized
lubrication system having a single
line circuit of SL-1, SLS-11, SL-32,
OR SL-33 Injectors.

It is an air operated reciprocating

pump that discharges an established
amount of lubricant *(.11 cu. in.) into
the circuit for each pump cycle.

*Based on lubricants that are free

of entrapped air. Lubricants that are
aerated will reduce output of pump.

FILL RESERVOIR
Use 81834 Manual Filler Pump to fill reservoir through the filler
fitting in the pump body. Attach coupler on delivery hose to filler.
Stroke filler pump handle until lubricant weepage is noted at air
vent hole in reservoir (lower portion of follower must rise beyond
air vent hole to expel entrapped air from lubricant).
NOTE: When filling the reservoir, caution should be used as extreme
pressure can cause damage to reservoir and follower assembly.

TO LUBRICATE
AIR VALVE MECHANISM

Disconnect air to pump, remove the four cover screws, cover plate
and cover gasket.

Remove and disassemble the air valve casting from the pump.

The air valve casting should be cleaned or flushed to remove any

chips, or other foreign particles prior to re-assembly.

Before replacing the toggle assembly, pack cavity with grease.

Form 403547
Use NLGI No. 1 (light grade) water repellent grease.
Approximately
1 1/2 ounces.

Replace cover gasket, cover and screws. Tighten to avoid air

leaks.
