Automatic Lubrication System - Section 42 OM4202 Page 42-2 Solenoid valve SV2 (8) directs the hydraulic fluid to the hydraulic cylinder which operates the grease pump. Pressure reducing valve (10) lowers hydraulic fluid pressure to the operating range of the hydraulic pump cylinder. It is factory set at its maximum pressure of 2069 kPa (300 psi), but may be adjusted lower. Cylinder pressure gauge (2) indicates hydraulic fluid pressure going to the hydraulic pump cylinder after passing through the pressure reducing valve.
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 valve body (3) and connected with a high pressure 1/4 in. hose to the top of vent valve assembly (11). Figure 42-2.
