Maintenance
Introduction
There is some basic maintenance that is recommended for the HercuLine
®
2000 Series Actuators. The
electronic PWAs within the actuator require no maintenance or servicing under normal conditions.
If there is a problem, refer to information in this section or to
Troubleshooting (page 105) .
Basic Maintenance
Position Sensor
Under normal conditions the position sensor does not require maintenance.
Main Gear Lubrication
Under normal operating conditions, the main worm gear should not require maintenance.
Spur Gear Lubrication
Honeywell recommends that during major shutdown periods the spur gears should be inspected and
lubricated. Follow the steps in
Table 35 to access the spur gear compartment and lubricate the gears if
necessary.
Disconnect power before opening the actuator case to inspect the actuator gears. A
potentially dangerous pinch hazard exists inside the case if the unit is open while
powered.
Table 35 Spur Gear Lubrication Procedure
Step Action
1 Remove AC power from actuator.
2 Remove the six screws and the bottom cover of the actuator case. See Figure 34.
3
Inspect the final spur gear, the idler gear and motor pinion for excessive wear and adequate
lubrication. See
Figure 34.
4
If needed, use Texaco Starplex 2 EP grease, or equivalent and apply lubricant to assure that
the gears are adequately protected.
5 Install a new gasket and replace side cover. Secure to actuator with screws.
6 Restore actuator to service.
