Automatic Lube System

LINCOLN AUTOMATIC LUBRICATION SYSTEM

The Lincoln Automatic Lubrication System is a pressur-
ized lubricant delivery system which delivers a control-
led amount of pressurized lubricant to designated lube
points. The system is controlled by an electric timer
which signals solenoid valves to cause operation of a
hydraulically operated grease pump.
For the 530M, these components (valves, pump, and
reservoir/cannister) are mounted on the right deck
structure to the right of the hydraulic cabinet just above
the right front suspension.

System Components

The system is comprised of these basic elements plus
the necessary hoses and lube lines:
1. Hydraulically Powered Reciprocating Cylinder
and Pump (1 & 5, Figure 4-5).
Pump Specifications:
16:1 Pressure Ratio.
NOTE: The theoretical ratio of the pump is 16:1.
Depending on application and variable internal
friction, the operational ratio is approximately
10:1.
Hydraulic Supply Pressure (Input):
300-3000 p.s.i. (2.1 - 20.1 MPa)
Input Flow (when pumping): 1.0 g.p.m. (3.8 l/min.)
Maximum Hydraulic Temperature: 210°F (98.8°C)
MAXIMUM Output Pressure: Not to Exceed
WARNING: Exceeding this value will damage
components and/or cause components to
rupture, resulting in possible serious injury to
any nearby personnel.
Output Flow: 11 cu. in./min. (180 cc/min.)
Operating Ambient Temperature:
-40°F to + 135°F (-40°C to + 57.7°C)
Seals: Buna-N
Filtration Required: 10 Micron (Hydraulic Supply)
24VDC power source.
2. Combination Valve Body (3, Figure 4-5) includes:
a. 24VDC Solenoid Valves (SV1 & SV2) are used
to control the hydraulically operated pump.
Solenoid Valve SVI (9) controls the supply of
hydraulic fluid to the pressure reducing valve
and to the vent valve.
Solenoid Valve SV2 (8) directs the hydraulic
fluid to the hydraulic cylinder which operates
the grease pump.
3500 p.s.i. (24.1 MPa)

7. Pump Cycle Timer
b. Pressure Reducing Valve:
The Pressure Reducing Valve (10) lowers hy-
draulic fluid pressure to the operating range of
the hydraulic pump cylinder.
It is factory set at its maximum pressure of 300
p.s.i. (2069 kPa), but may be adjusted lower.
c. The Cylinder Pressure Gauge (2): indicates
hydraulic fluid pressure going to the hydraulic
pump cylinder after passing through the pres-
sure reducing valve.
d. Orifice Fitting Assembly (4): meters hydraulic
pressure from the pressure reducing valve to
the top of the vent valve assembly (this permits
even operation of the vent valve, without
shock). This fitting is assembled to the side of
the Valve Body (3) and connected with a high
pressure 1/4 in. hose to the top of the Vent Valve
Assembly (11).
