7. MEASUREMENT OF HYDRAULIC PUMP CASE PRESSURE
7-1. Measurement of Propulsion Pump Case Pressure
• Oil temperature during measurement : 50
± 5
°C (122
± 41
°F)
①
Disconnect hose from propulsion pump. Attach pressure
gauge with adapter ⓩ .
• Adapter
ⓩ
: 1 1/16-12UN
• Pressure gauge : 0 to 5 MPa (0 to 725 psi)
②
Start the engine and set throttle lever to “Full”.
③ Establish a condition in which machine propulsion load
becomes maximum. (Pressure does not build up unless
propulsion load is applied.)
④
With propulsion load at maximum, measure pressure
when F-R lever is in “N”, “F”, and “R”, respectively.
★ Pump case pressure : 0.25 MPa (36.3 psi) or less
• The number “1-14” appearing in above illustrations is consistent with lead line numbers shown in illustration
of propulsion pump in “2-2. Hydraulic Component Speci fi cations” (page 4-010).
