FORWARD MAIN RELIEF VALVE PRESSURE TEST - Continued
Minimum low pressure is 6,327 psi (43,623 kPa).
If minimum low pressure is not obtainable, there is too much leakage in the internal circuit and pump must be

HYDRAULIC SERVO NEUTRAL (MECHANICAL CENTER) ADJUSTMENT
Charge Pump System Pressure Test must be completed before performing Hydraulic Servo
Neutral (Mechanical Center) Adjustment.
Place propel control lever in NEUTRAL (TM 5-3895-379-10).
The following step equalizes oil pressure on each side of servo piston.
Remove two plugs (Figure 8, Item 1) from ports (Figure 8, Item 2) and connect jumper hose between two ports.
