INSPECTION AND ADJUSTMENT
2. MEASUREMENT AND ADJUSTMENT OF PROPULSION
CIRCUIT PRESSURE
2-1. Measurement
WARNING
Confirm that the parking brake works properly before
measurement.
• Oil temperature during measurement : 50
± 5
°C (122
± 41
°F)
①
Remove plugs from high pressure gauge port (1-8) and
(1-9) of propulsion pump. Attach pressure gauge with
adapter
ⓗ
.
• Adapter : 9/16-18UNF
• High pressure gauge port (Reverse) : (1-8)
• High pressure gauge port (Forward) : (1-9)
• Pressure gauge
: 0 to 50 MPa
(0 to 7,250 psi)
②
Set propulsion speed change switch to “ ” position.
③
Start the engine and set throttle lever to “Full” position.
④
Establish a condition in which machine propulsion load
becomes maximal. (Pressure does not build up unless
propulsion load is applied.)
⑤
With propulsion load at maximum, slowly move F-R lever
to the side to be measured.
• Then, read pressure indicated by pressure gauge.
⑥
After measuring, promptly return F-R lever to “Neutral”
position.
★
Maximum circuit pressure
(high pressure relief valve setting)
: 41.8
± 1.0
MPa (6,061
± 145
psi)
• The numbers “1-8” and “1-9” appearing in above illustrations are consistent with lead line numbers shown in
illustration of propulsion pump in “2-2. Hydraulic Component Specifications” (page 4-007).
