OM4202 Automatic Lubrication System - Section 42 Page 42-1 LINCOLN AUTOMATIC LUBRICATION SYSTEM The Lincoln Automatic Lubrication System is a pres- surized lubricant delivery system which delivers a controlled amount of pressurized lubricant to desig- nated 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 HD1500-5, these components (valves, pump, and reservoir/canister) 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: Hydraulically Powered Reciprocating Cylinder and Pump (1 & 5, Figure 42-1) Pump Specifications: Pressure ratio: 16:1 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): 2.1 - 20.1 MPa (300-3000 psi) Input flow (when pumping): 3.8 l/min (1.0 gpm) 1. Pump Cylinder 2. Cylinder Pressure Gauge 3. Valve Body Assembly 4.

Fill Supply Port Maximum hydraulic temperature: 99°C (210°F) Maximum output pressure: 24.1 MPa (3500 psi) WARNING: Exceeding this value will damage components and/or cause components to rupture, resulting in possible serious injury to any nearby personnel. Output flow: 180 cc/min (11 cu. in./min) Operating ambient temperature: -40°C to +58°C (-40°F to +135°F) Seals: Buna-N Combination valve body (3, Figure 42-1) includes: Filtration required: 10 micron (hydraulic supply) 24VDC power source.
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.
