INSPECTION AND ADJUSTMENT
3. MEASUREMENT AND ADJUSTMENT OF PROPULSION
CHARGE CIRCUIT PRESSURE
Since oil in charge circuit is supplied from steering
circuit, confirm that steering operation is normal before
measurement.
Propulsion charge circuits and vibration charge circuits
consist of parallel circuits. Thus, in order to measure
whether vibrator charge circuit pressure is within standard
value, use following operation to ensure that oil does not
escape to the charge relief valve on vibrator pump side.
①
Loosen nut (1) from charge relief valve (2-8) on vibrator
pump side.
②
Tighten adjustment screw (2) by two complete turns.
Adjustment screw turned clockwise
: Pressure rise
Adjustment screw turned counterclockwise
: Pressure drop
Pressure change rate : 0.56 MPa/turn (81.2 psi/turn)
The number “2-8” appearing in above illustrations is consistent with lead line numbers shown in illustration of
vibrator pump in “2-2. Hydraulic Component Specifications” (page 4-007).
