METHODS FOR INSPECTING PERFORMANCE

Hydraulic Oil Pressure (Main Relief Valve Set
Pressure)
Boom, Arm, Dozer Blade

Measuring Method

• Engine

: Rated r.p.m.

• Hydraulic Oil Temp. : 50~60

• Mount the pressure gauge on the pressure detec-

tion port, operate the desired hydraulic circuit
and measure the relief pressure.

Adjusting Method

1. Loosen locknut (2), then begin adjusting pressure

by turning setting screw (1).
Turning clockwise ................ raises the set pressure.
Turning counterclockwise .... lowers the set pressure.

2. In order to keep the setting screw from turning

after pressure has been adjusted, tighten the lock-
nut while at the same time holding the setting
screw firmly in place.
• Locknut tightening torque:

20 N·m (2 kgf·m) ...................TB125, TB135
27~31 N·m (2.8~3.2 kgf·m) ...TB145

3. Operate the relief valve once more to confirm that

the pressure that has been set it stabilized.

Hydraulic Oil Pressure (Slewing Relief Valve
Set Pressure)

Measuring Method

• Engine

: Rated r.p.m.

• Hydraulic Oil Temp. : 50~60

• Mount the pressure gauge on the pressure detec-

tion port and set a solid obstacle so that the
upperstructure cannot slew in the direction to be
measured. Next, operate the circuit to be mea-
sured and measure the relief pressure.

Adjusting Method

1. Loosen locknut (2), then begin adjusting pressure

by turning setting screw (1).
Turning clockwise ................ raises the set pressure.
Turning counterclockwise .... lowers the set pressure.

2. In order to keep the setting screw from turning

after pressure has been adjusted, tighten the lock-
nut while at the same time holding the setting
screw firmly in place.

3. Operate the relief valve once more to confirm that

the pressure that has been set it stabilized.

Adjusting Method

1. Loosen locknut (2), then begin adjusting pressure

by turning setting screw (1).

Turning counterclockwise .... lowers the set pressure.

2. In order to keep the setting screw from turning
