Oil Hydraulic Motor (Actuator) Inspection Procedure
| 1. |
Remove the coupling assembly.
(Refer to 4WD Control System - "Coupling Assembly")
|
| 2. |
Keep going perpendicular state after remove the coupling assembly.
| •
|
Keep going perpendicular state during remove (install)
the hydraulic motor (actuators).
|
| •
|
Use a tool (A) that allows the auxiliary operator to
hold or seat the coupling in a vertical position.
|
| •
|
So that the input shaft side (B) is not damaged.
|
|
|
| 3. |
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)
|
|
|
| 1. |
Before installation, wipe the surface (A) with a clean cloth.
|
| 2. |
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.
|
|
|
| 3. |
After mounting the hydraulic motor (actuator) (A), tighten the bolts.
| •
|
When installing, motor connector has to toward in the
direction of outside of the Coupling.
|

|
Change direction in the direction of the arrow and lay
on the floor as shown in the illustration.
※ The reflux oil will flow to the bottom.

to order as shown in the illustration.
|
|
|
| 4. |
