Maintenance - Section 4 OM4006.2 10/98 Page 4-24 Automatic Lube System POSSIBLE CAUSES SUGGESTED CORRECTIVE ACTION TROUBLE: Timer Turns On At Intervals Two (2) To Ten (10) Times More Often Than Set Time Interval: Electrical noise is being introduced into the power supply to the timer overcoming suppressor capacitor causing uncontrolled turn-on of its output relay. IMPORTANT: In some instances, electrical noise may be generated into vehicle electrical system which may cause timer to turn on at random inter- vals, independent of timer setting.
If this occurs, a 250 to 1,000 MFD capacitor rated 150 to 350 VDC should be added across BAT (+ ) and BAT (-) terminals to suppress this noise and improve timer performance. TROUBLE: Timer Turns On At Intervals Faster Than Allowable Tolerances Of Settings: Timer out of adjustment or damaged component. Refer to ‘‘Timer Adjustment and re-adjust timer, or replace timer. Reservoir Fill Procedure Lubricant Required for System Refer to ‘‘Lubrication Chart’’, for correct lubricant speci- fications. . Above 90°F (32°C) - Use NLGI No.2 multipurpose grease (MPG). . -25° to 90°F (-32° to 32°C) - Use NGLI No. 1 MPG. .
Below -25°F (-32°C) - Refer to local supplier for extreme cold weather lubricant requirements. Fill Procedure 1. Remove top vent plug (14, Figure 4-12). 2. Remove bottom fill plug (15). 3. Connect line from Lubricant Delivery system to bottom fill port (15) and fill reservoir until grease just begins to come out of top vent hole above. 4. Disconnect line from Lubricant Delivery system and install plugs (14 & 15) previously removed. 1. Pump Cylinder 8. Solenoid Valve, SV2 2. Cyl. Pressure Gauge 9. Solenoid Valve, SV1 3.
