PRESSURE SETTING PROCEDURES
Objective
To assist personnel in properly checking, adjusting and
setting the hydraulic system pressures.
Equipment
Required pressure gauge analog or digital capable of
reading 0-34.5 MPa (0-5000 psi). (1) Parker Diagnostic
Quick Disconnect p/n PD240 for carrier and (1) Parker EMA
gauge adapter for the superstructure.
Valve Pressure Setting Table
NOTE:
Reservoir oil temperature to be approx. 120-140° F
(49-60° C) to check pressures.
Set pressure to nominal value to account for
tolerance of gauge.
The below values indicate what the pressure
gauge must read at the pressure check ports
therefore listed pressures may not match the
values shown on the hydraulic schematic.
