Lubrication & Service - Section 4 OM4015.2 10/98 Page 4-12 Lincoln Automatic Lubrication System 4. Solenoid Air Valve - Three-way a. Routes system air to the appropriate locations in the lube system. Initial Reservoir Fill 1. Remove 0.50 in. (1.27 cm) pipe plug (13, Figure 4-1) from upper portion of lubricant reservoir. This will prevent damage to reservoir by allowing air to escape as reservoir is being filled. b. Power requirement for solenoid air valve and timer is 15 watts. 5. Injectors (SL-1) 2. Clean grease coupler (14) on lower portion of reservoir. a. Each lube injector services only one grease point. b.
Injectors are available in banks of two, three, four and five as well as single replacement units. 3. Attach supply hose from external fill source to coupler (14). 4. Fill reservoir with approximately 60 lbs. (27.24 kg) of grease. When reservoir is filled, grease will appear at upper pipe plug hole (13). c. Injector output is adjustable: Maximum output = 0.08 in 3 (1.31 cc). Minimum output = 0.008 in 3 (0.13 cc). 5. Remove supply hose from grease coupler (14). Remove excess grease from coupler. Install pipe plug (13) and tighten to standard torque. d. In case of air pump malfunction, each injector is equipped with a covered grease fitting to allow the use of external lubricating equipment.
GENERAL INSTRUCTIONS System Priming Lubricant Required for System The system must be full of grease and free of air pockets to function properly. After maintenance, if the primary or secondary lubrication lines were replaced, it will be necessary to reprime the system to eject all entrapped air. To run the air pump when priming the lube system, connect a jumper wire between the igni- tion and solenoid posts on the solid state timer. Refer to “Lubrication Chart”, Lube Key E, for correct lubricant specification and for specific lube points for a specific truck model. 1. Above 90°F (32°C) - Use NLGI No.2 multipurpose grease (MPG). 1. Fill lube reservoir with lubricant, if necessary. 2.
-25° to 90°F (-32° to 32°C) - Use NGLI No. 1 MPG. 2. Remove plugs from all injector manifold dead ends and supply lines. 3. Below -25°F (-32°C) - Refer to local supplier for extreme cold weather lubricant requirements. FIGURE 4-2. REAR LUBE INJECTOR INSTALLATION (TYPICAL) 1. Suspension, Lower LH 5. Body Pivot, L.H. 9.
