1. Remove retaining ring (6).
2. Install damper arm (7).
3. Install return spring (8) and spring plug (9) if required
(440006 only).
4. Secure the assembly with the retaining ring (6) removed
in step 1, above.
5. Reconnect the wiring and cycle the actuator to verify

Refilling Hydramotor
r
Actuator with Hydraulic Oil
and Purging Entrapped Air
1. When refilling a Hydramotor
r
Actuator with oil, it is
recommended that the actuator be energized and
de-energized during filling (if possible). This is
particularly important if the oil level in the reservoir is
very low or empty. By operating the actuator, entrapped
air is purged from the hydraulic system. If upon
energizing the Hydramotor
r
Actuator the actuator fails
to move, delays or operates slowly, chances are air has
become entrapped in the hydraulic system.
Remove entrapped air from the hydraulic system by
cycling the actuator 4 to 5 times successively over the full
stroke. As air is purged, check oil level and add oil if
necessary. All of the air has been removed when the
actuator stem moves immediately upon energizing.
2.
With Actuator Mounted Upright,
(Figure 2), remove oil fill
plug and fill to bottom of fill port, follow instructions
provided in step 1.
3.
With Actuator Mounted On Its Side,
and oil fill plug
uppermost, remove the oil fill plug. The oil level should
be 5/8
I
from the top of the pump cover. Follow
instructions provided in step 1.
4. Reinstall fill plug and torque to 114-120 in-lbs [13-14
Nm].
5. If actuator has been repositioned, return unit to normal
orientation.
6. Before returning to service, cycle the actuator to verify
proper operation.
