Test 19—Setting Pump Neutral
To set pump neutral, perform the following procedure.
1. Make sure the engine is off and the power is on, with all
brakes and locks engaged.
2. Disconnect the PC from the pump EDC by removing the
cable at the EDC.
3. Install a 0 to 42 bar (0 to 600 psi) gauge at each servo
gauge port (2).
4. Start the engine with all brakes and locks engaged.
5. Loosen the hex lock nut and rotate the neutral adjusting
screw (1) with a hex wrench until the pressure increases
in one of the gauges.
6. Note the handle position of the hex wrench and without
moving the wrench, rotate the neutral adjusting screw
counterclockwise until the pressure increases in the
other gauge.
7. Note the handle position of the hex wrench again and
without moving the wrench, rotate the neutral adjusting
screw clockwise halfway between the last position.
The control should now be in neutral with both gauges
reading the same case pressure.
8. Hold the neutral adjusting screw with the hex wrench
and tighten the lock nut.
9. Remove the gauges and install the servo gauge port
plugs.
