4. MEASUREMENT OF PROPULSION SERVO CIRCUIT
PRESSURE

4-1. Measurement

• Oil temperature during measurement : 50
① Disconnect hoses (1) and (2) from propulsion pump.
Attach pressure gauge through adapter ⓜ .
• Adapter ⓜ
• Pressure gauge : 0 to 5 MPa (0 to 725 psi)
② Confirm that F-R lever is "N".
③ Apply parking brake by pressing parking brake switch
button.
④ Start the engine and set throttle lever to "FULL".
⑤ Operate F-R lever and then read pressure indicated by
pressure gauge.
• with parking brake applied (ON), measured pressures
of (1) and (2) are same.
• with parking brake released (OFF), measured
pressures of (1) and (2) are different.
