Oil Hydraulic Motor (Actuator) Repair Procedures

Inspection

If there is a diagnostic trouble code related to the oil hydraulic motor (actuator), inspect the oil hydraulic motor (actuator) in accordance with the inspection procedure.

Oil Hydraulic Motor (Actuator) Inspection Procedure

Removal

1. 1
   Remove the coupling assembly. (Refer to Coupling Assembly - "Removal").
2. 2
   Keep the coupling perpendicular after removing the coupling assembly.

   Keep the oil hydraulic motors (actuators) perpendicular during removal and installation.

   

3. 3
   Remove the hydraulic motor (A) after first loosening the bolts with a hex key.

   Remove the oil hydraulic motors (actuators) after draining residual oil into the coupling as much as possible. (Approx. 5~10 sec)

   

Installation

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

   

2. 2
   Inspect the O-rings (A) of the new hydraulic motor (actuator).

   

   Prevent dust from entering the oil hydraulic motors (actuators) and the housing.

3. 3
   Tighten the bolts after installing the hydraulic motor (drive).

   When installing, the motor connector must face outward from the coupling.

   Tightening torque: 8.8 - 10.8 N·m

   

   During installation, oil may leak out due to pressure in the breather hole. Change direction in the direction of the arrow and lay flat as shown in the illustration. x Residual oil will drain to the bottom. Prevent additional oil backflow by following the sequence shown in the illustration.

4. 4
   Wipe off leaked oil from the surface with a clean cloth.

   

5. 5
   Install the coupling assembly. (Refer to Coupling Assembly - "Installation")
