Actuator Maintenance and Adjustment
A) Actuator Tension Adjustment
The lid on the ALLGB and ALLGB-F(standard on 60 gallon
and up) can operate with spring-loaded actuators. If the
lid can be raised to any position, and it remains in that
position, the actuators are adjusted properly. Should the
tension need adjustment after shipping, or at any time
in the future, the following procedure can be performed.
Raise the unit's lid completely. Removal of the stop nut
may be needed to raise the lid completely.
Remove the tube closure cap on the actuator. With a 3/4"
deep hex socket, turn the adjusting nut (located inside
the actuator sleeve) clockwise to increase the tension or
counterclockwise to decrease tension. Rotate the nut
one turn at a time and test the lid's operation. When the
adjustment is complete, replace the tube closure cap on
the actuator sleeve.
B) Actuator: Re-Packing With Grease
The lid actuator(s) of your unit must be re-packed with
grease every six months to ensure proper operation.
Perform the following steps. Refer to Figure 3.1 and to
Figure 3.2.
1. Raise the lid of the unit fully.
2. Remove the tube closure cap.
3. Remove the self-locking 1/2-13 hex nut on the actuator
rod.
4. If the components inside the actuator sleeve do not
slide out easily, remove the bolt, which secures the
actuator sleeve to the frame lug. Put aside the bolt, nut,
and lock washer for re-assembly later.
5. Grasp the actuator sleeve and pull down away from the
actuator rod. The components inside the actuator sleeve
will slide out.
6. Pack the spring (or springs) with Bel-Ray No-Tox Clear
Grease #2. The grease must be liberally applied between
each coil.
7. After re-packing with grease, reassemble the
components back inside the actuator sleeve and slide the
sleeve back over the actuator rod.
8. Reconnect the actuator assembly to the frame lug
using the bolt, nut, and lock washer previously set aside.
9. Adjust the tension of the actuators using the procedure
described earlier in this section.
C) Actuator Replacement
Should the actuators on your unit ever require
replacement, use the following procedure. Refer to Figure
3.1 and to Figure 3.2.
1. Raise the lid of the unit fully.
2. Remove the tube closure cap.
3. Using a deep socket tool, loosen the self-locking hex
nut on the actuator rod (by turning it counterclockwise)
to eliminate pressure on the springs.
4. From the pivot arm of the actuator, remove the acorn
nut, bolt, lock washer, and spacer and retain them for
mounting the new actuator(s).
5. From the frame lug (at the other end of the actuator)
remove the acorn nut, bolt, and lock washer and retain
them for mounting the new actuator(s).
6. Mount the new actuators using the bolts, nuts, lock
washers, and spacers set-aside in the above steps.
Note: The actuator rod must be free to pivot during use.
Therefore, when tightening the hex bolt into the acorn
nut, tighten it completely, and then back off a half turn.
7. After the new actuator(s) are installed, adjust the tension
using the procedure described earlier in this section.
