MEASUREMENT AND ADJUSTMENT OF PROPULSION CHARGE CIRCUIT PRESSURE
3. MEASUREMENT AND ADJUSTMENT OF PROPULSION
CHARGE CIRCUIT PRESSURE
Before measuring
Since charge circuit oil is being supplied from
the steering circuit, first confirm that the steering
operation is normal.
The propulsion charge circuits and vibration
charge circuits consist of parallel circuits. Thus,
in order to measure whether the propulsion
charge circuit pressure is within the standard
value, use the following operation to ensure that
oil does not escape from the charge relief valve
on the vibrator pump side.
①
Remove the plug (1) from the charge relief valve
(2-7) on the vibrator pump side.
②
Insert a spacer (ø12 mm × t 10 mm) as shown
in the figure on the right.
③
Attach the plug (1).
3-1. Measurement
Oil temperature during measurement
: 50 ± 5°C (122 ± 41°F)
①
Remove the plug from the charge pressure
gauge port (1-8). Attach the pressure gauge
through the adapter
ⓕ
.
Gauge port: 7/16-20UNF
Pressure gauge: 0 – 4.9 MPa (0 – 711 psi)
②
Press the parking brake switch and turn the
parking brake “ON”.
③
Start the engine, move the throttle lever to the
high idling position, and measure the pressure.
Standard charge relief pressure setting
: 2.5 ± 0.2 MPa (362.5 ± 29 psi)
