INSPECTION AND ADJUSTMENT
7. MEASUREMENT AND INSPECTION OF VIBRATOR
CIRCUIT PRESSURE
7-1. Measurement
CAUTION
Take care not to operate the vibratory drum for a
longer period of time than necessary with the machine
stationary. Otherwise, the vibrator bearing could be
seized.
Oil temperature during measurement : 50
± 5
°C (122
± 9
°F)
①
Remove plugs from couplings (1) and (2) of vibrator
pump. Attach pressure gauge with hose
ⓢ
and connector
ⓤ
.
Coupling : 9/16-18UNF×M16
Adapter for hose
ⓢ
: M16 P=2.0
Pressure gauge connector
ⓤ
: M16×G3/8
High pressure gauge port : (1)
(low amplitude)
High pressure gauge port
: (2)
(High amplitude)
Pressure gauge
: 0 to 50 MPa
(0 to 7,250 psi)
②
Confirm that F-R lever is “N”.
③
Apply parking brake by pressing parking brake switch
button.
④
Set vibration mode change switch to “ ”.
⑤
Start the engine and set throttle switch to “FUll”.
⑥
Press F-R lever vibration switch ON.
⑦
Read pressure gauge for maximum value of vibrator
circuit pressure.
⑧
Turn F-R lever vibration switch OFF as soon as
measurement is finished.
Maximum circuit pressure
(high pressure relief valve setting)
: 25.0
± 1.0
MPa (3,625
± 145
psi)
