PERFORMANCE CRITERIA
2D0AX002
Hydraulic oil pressure (Slew)
Measurement method
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Install a pressure gauge on the pressure detection
port. Operate the hydraulic circuit to be tested, and
measure the relief pressure. (Secure the upper struc-
ture so that it cannot slew in the direction to be mea-
sured.)
Adjustment method
The set pressure cannot be adjusted while the relief
valve is attached to the slew motor. If adjustments need
to be made, replace the relief valve assembly.
Hydraulic oil pressure (Pilot pressure)
Measurement method
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Install a pressure gauge on the pressure detection
port to measure the relief pressure.
Adjustment method
1. Loosen the locknut (1), and turn the setscrew (2) to
adjust the set pressure.
• Turn the setscrew clockwise to increase the set
pressure.
• Turn the setscrew counterclockwise to decrease
the set pressure.
2. In order to keep the setscrew (2) from turning after
the pressure has been adjusted, tighten the locknut
(1) while holding the setscrew (1) firmly in place.
Locknut: 15.7 N·m (11.6 ft.-lb)
3. Operate the relief valve once more to confirm that the
pressure that has been set is stabilized.
