°C (122
± 41
°F)
①
Remove the plugs from the servo pressure gauge port (1-2)
and (1-7). Attach the pressure gauge through the adapter
ⓑ
.
Gauge port : G1/4
Pressure gauge : 0 to 5 MPa (0 to 725 psi)
②
Apply the parking brake by pressing the parking brake
switch button.
③
Start the engine and set the throttle switch to the “Full”
position.
④
Operate forward-reverse lever and perform pressure
setting.
When forward-reverse lever is in “Neutral” position,
pressure reading at (1-2) and (1-7) should be the same.
When forward-reverse lever is moved to either direction,
pressure readings will be different.
Standard charge relief pressure setting
: 2.7

MPa (392
± 14.5
psi)
The number “1-2” and “1-7” appearing in the above illustrations are consistent with the lead line numbers
shown in the illustration of the propulsion pump in “2-2. Hydraulic Component Specifications” (page 4-007 and
4-008).
