INSPECTION AND ADJUSTMENT
9. MEASUREMENT OF PROPULSION MOTOR CASE
PRESSURE
9-1. Measurement of Propulsion Motor (F)
Oil temperature during measurement : 50
± 5
°C (122
± 9
°F)
①
Disconnect hose (1) and (2) from propulsion motor. Attach
pressure gauge through adapter
ⓟ
.
Hose (1) : Propulsion motor (F,R)
Hose (2) : Propulsion motor (F,L)
Adapter
ⓟ
: G1/2
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 “ ” and “ ” and F-R
lever is “N”, “F”, and “R”, respectively.
Allowable motor case pressure
: 0.3 MPa (43.5 psi) or less
