Measured data
•
Servo pressure at M4 (refer to Port locations and gauge installation on page 13)
•
Servo pressure at M5 (refer to Port locations and gauge installation on page 13)
•
Pressure differential between M4 and M5 (optional)
Procedure
1. Attach 20 bar [300 psi] gauge to each servo gage port.
2. Use a 5/32 internal hex wrench to hold the adjusting screw in place.
3. Using a 1/2 hex wrench, loosen locknut.
4. Start prime mover and slowly accelerate to normal operating RPM.
5. Rotate adjustment screw until both servo gages read equal pressures. Rotate adjustment screw until
one of the servo pressure gages indicates an increase in pressure. Rotate adjustment screw in
opposite direction until the other servo pressure gage indicates an increase in pressure. Rotate
adjustment screw until it is half way between the two positions.
6. While holding the neutral adjustment screw in place, tighten locknut. Torque to 3 Nm [27 in•lb].
