maxpressure rating
General Description
The Lincoln Industrial rotary A/C electric pump uses a 120-
230 VAC dual voltage motor and a single stage planetary
gear drive. Grease output is proportional to the pump RPM.
The pump is primarily designed for centralized lubrication
systems such as the Single Line parallel, Single Line
Progressive and Two Line systems.
The pump is driven by the rotary motion of the electric motor.
Rotary motion is converted to reciprocating motion through
an eccentric crank mechanism. The reciprocating action
causes the pump cylinder to move up and down. The unit is
a positive displacement double acting pump as grease
output occurs during both the up and down stroke.
During the down stroke, the pump cylinder is extended into
the grease. Through the combination of shovel action and
vacuum generated in the pump cylinder chamber, the grease
is forced into the pump cylinder. Simultaneously, grease is
discharged through the outlet of the pump. The volume of
grease during intake is twice the amount of grease output
during one cycle. During the upstroke, the inlet check
closes, and one half of the grease taken in during the
previous stroke is transferred through the outlet check and
discharged to the outlet port. Typical output of the pump is
shown on page 3.
Appropriate Use
•All pump models are exclusively designed to pump and
dispense lubricants using 120 VAC or 230 VAC electric
power, depending on how the motor is wired.
•The maximum specification ratings should not be
exceeded.
•Any other use not in accordance with instructions will
result in loss of claims for warranty and liability.

Safety
Read and carefully observe these operating instructions
before unpacking and operating the pump! The pump must
be operated, maintained and repaired exclusively by persons
familiar with the operating instructions. Local safety regula-
tions regarding installation, operation and
maintenance must be followed.
Operate this pump only after safety instructions and this
service manual are fully understood.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
Safety Instructions
This equipment generates very high grease pressure.
Inspection
If overpressurizing of the equipment is believed to have
occurred, contact the factory authorized warranty and service
center nearest you for inspection of the pump.
Specialized equipment and knowledge is required for repair
of this pump. Contact the factory authorized warranty and
Extreme caution should be used when operating this
equipment as material leaks from loose or ruptured
components can inject fluid through the skin and into the
body causing serious bodily injury. Adequate protection is
recommended to prevent splashing of material onto the
skin or into the eyes.
If any fluid appears to penetrate the skin, get emergency
medical care immediately. Do not treat as a simple cut.
Tell attending physical exactly what fluid was injected.

InstallingthePump
Typical installation is shown only as a guide for selecting
and installing system components. Contact your Lincoln
Industrial representative for assistance in designing a
system to suit your specific needs.
The pump was tested in light weight oil which was left in to
protect the pump from corrosion. Flush the pump before
connecting it to the system to prevent contamination of the
grease with residual oil.

1. Mount the pump securely on the drum cover so that it
cannot move or vibrate during operation.
2. Connect material supply line to the pump outlet. Install
Safety Unloader Valve (such as 272722)to the outlet on
the opposite side of the pump to ensure the maximum
pressure is always below 5,00 psi.
3. Install high pressure shut-off valve in the material supply
line. (Required)
4. Connect 120 VAC or 230 VAC power supply to the
solenoid valve (35). (See Illustration #1.)
5. Wire the motor for the proper voltage and connect motor
power lines. Be sure to fuse the motor as recommended
in in Illustration 3 (See illustration #2).
6. Mount the motor to the drum cover using the auxillary
mount.
Mount the pump securely on the drum cover. Failure to do so
could result in personal injury and equipment damage.
Always install a relief valve in the pump outlet to insure pump
pressure is below 5,000 PSI. Use high pressure compo-
nents to reduce risk of serious injury including fluid injection
and splashing in the eyes or on the skin.

1. Remove the pump outlet line.
2. With the pump in a full container of lubricant, energize the
pump. Make sure all air has been expelled from the
pump and even lubricant flow is achieved.
3. Reattach the pump outlet line.
Never allow the pump to run dry of lubricant. Monitor the
supply lubricant level and refill when necessary.
MaintenanceandRepair
Relieve pressure from the pump and supply lines before
servicing or repairing the pump, to reduce the risk of an injury
from injection, splashing fluid or moving parts.
* A field installed fuse of 5 amps@ 120 VAC (3 amps @ 230
VAC) is recommended.
Always use Lincoln Industrial parts for service and repair.
Crank Case Oil
Check the oil after every 100 hours of operation or monthy.
The crankcase should be filled to the center of the pump-
shaft. Change the oil after every 500 hours of operation.
Use SAE 10W30 motor oil in all units.

ing the four mounting screws (46).
3.Remove four screws (48) and remove gearset(s) and
spacer, if applicable.
4.Remove the shaft adapter (41). This part is removed by
pulling it straight out of the pump shaft (37).
5.Remove the pump housing cover (30) and gasket (31).
Drain the crankcase oil from the open housing.
6.Remove the bearing cover (64).
7.Remove the pump shaft snap ring (62).

PumpAssembly Procedure
1. When the pump is dissembled, it is recommended to
replace all seals and gaskets, which are included in the
270663 repair kit. In addition, replace o-rings (44), (36)
and (63).
2. In the process of disassembly, examine the following
components and replace if excessive wear is indicated:
ball bearing (7), crank eccentric (6), crankrod (4), wrist
pin bushings (12), plunger tube (10), pump plunger and
upper check parts (19, 18 and 17), pump cylinder (23),
check seat housing and lower check ball (27 and 25),
upper bronze bushing (52), housing tube (27), shovel
plug (59), and reciprocating tube (20). Also check shaft
seal (40).
3. Assembly Procedure is the reverse of the Disassembly
Procedure except for the following:
4. Install parts (21) through (27) into the reciprocating tube
(20) after the plunger assembly (8 through 19) is
installed.
5. Install the pump subassembly (1 through 27) into the
pump housing (68) before tightening the housing tube
(56) to the pump housing (68). Be sure the
reciprocating tube (20) is inserted through both
bushings before tightening the housing tube (56).
6. When pressing the pump shaft in (37), support the inner
race of the rear ball bearing (60) and the crank assembly
(1 through 7) to insure proper assembly.
7. If replacing the pump shaft ball bearings (38 & 60),
support the housing (68) inner wall behind the snap rings
(39 & 61) when re-installing the bearing.
8. Use loctite 242 (or similar product) medium strength
thread lock on all torqued threaded connections. Extreme
care must be exercised to prevent excess compound
from flowing into critical areas such as clearance fits and
ball check. Allow a minimum of 30 minutes cure time
before operating the pump.
