°F)
①
Remove plugs from servo pressure gauge ports (2-3) and
(2-10). Attach pressure gauge with the adapter
ⓗ
.
Adapter
ⓗ
: 9/16-18UNF
Servo pressure gauge port (low) : (2-10)
Servo pressure gauge port (High) : (2-3)
Pressure gauge
: 0 to 5 MPa
(0 to 725 psi)
②
Confirm that F-R lever is “N”.
③
Apply parking brake by pressing parking brake switch
button.
④
Start the engine and set throttle switch to “FUll”.
⑤
Set vibration select switch and then read pressure
indicated by pressure gauge.
With vibration select switch is “ ”, measured pressures
of (2-3) and (2-10) are same.
With vibration select switch is “
” or “ ”, measured
pressures of (2-3) and (2-10) are different.
Standard charge relief valve setting
: 2.5

psi)
The numbers “2-3” and “2-10” appearing in above illustrations are consistent with lead line numbers shown in
illustration of pump ASSY in “2-2. Hydraulic Component Specifications” (page 4-006).
