9. MEASUREMENT OF PROPULSION MOTOR CASE
PRESSURE

9-1. Measurement of Propulsion Motor (F)

• Oil temperature during measurement : 50
① Disconnect hose (1) and (2) from propulsion motor. Attach
pressure gauge through adapter ⓟ .
• Hose (1)
• Hose (2)
• 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 Set speed change switch to "
⑤ Start the engine and set throttle lever to "FULL".
⑥ Establish a condition in which machine propulsion load
becomes maximum. (Pressure does not build up unless
propulsion load is applied.)
⑦ With propulsion load at maximum, measure pressure
when speed change switch is "
lever is "N", "F", and "R", respectively.
