INSPECTION AND ADJUSTMENT
6-1-2. Measurement of port relief pressure
①
Disconnect the hose (1), (2), (3) and (4) from the vibrator
solenoid valve. Attach the pressure gauge through the
adapter
ⓟ .
Adapter

: G1/2
Front drum low-amplitude side port : (1)
Front drum high-amplitude side port : (2)
Rear drum high-amplitude side port : (3)
Rear drum low-amplitude side port : (4)
Pressure gauge
: 0 to 25 MPa
(0 to 3,625 psi)
②
Apply the parking brake by pressing the parking brake
switch button.
③
Set the vibration mode (continuous/automatic) selector
switch to the “Continuous” position.
④
Set the vibration frequency selector to the “3,000 vpm”
position.
⑤
Start the engine and set the throttle switch to the “Full”
position.
⑥
Set the vibrator switches to the “HIGH” or “LOW” position
respectively.
⑦
Press the F-R lever vibrator switch to turn the vibrator
drum “ON”. Then, read the pressure gauge for the
maximum value of the high or low-amplitude side port
vibrator circuit pressure.
(NOTICE)
Take care not to operate the vibratory drum for a
longer period of time than necessary with the vehicle
stationary. Otherwise, the vibrator bearing could be
seized.
⑧
Turn the vibrator drum “OFF” as soon as the
measurement is finished.
Standard port relief pressure setting
: 24.0
± 1.0
