Inspection

If you have trouble code related to the oil hydraulic motor (actuator), check oil hydraulic motor (actuator) according to the inspection process.

Oil Hydraulic Motor (Actuator) Inspection Procedure

Removal

1.	Remove the coupling assembly. (Refer to Coupling Assembly - " Removal ")

Keep going perpendicular state after remove the coupling assembly.

•	Keep going perpendicular state during remove (install) the hydraulic motor (actuators).

Remove the hydraulic motor (A) after loosening bolts with hex wrench.

•	Remove the hydraulic motor (actuators) after dropping residual oil as much as possible inside the coupling. (abut 5~10 sec)

Installation

1.	Before installation, wipe the surface with a clean cloth.

Check the O-rings (A) of the new hydraulic motor (actuators).

•	You have to prevent any dust from entering inside hydraulic motors (actuators) and housing.

Tighten the bolts after install the hydraulic motor (actuators).

•	When installing, motor connector has to toward in the direction of outside of the Coupling.

Tightening torque:

8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~ 8.0 lb-ft)

•	When installing, oil can be reflux by the pressure in air breather hole.
