CAUTION: Avoid reattaching the handwheel as-
sembly to the yoke while the actuator remains in
service. If the actuator remains in service during
handwheel reassembIy, ensure that the
handwheel is in the neutral position and that
hands and clothes are kept away from moving
parts to avoid injury.
SIDE-MOUNTED, CONTINUOUSLY
CONNECTED HANDWHEELS, SIZE 100
AND 200 (Linear Actuators only)
Operation
See 'Operation' under Size 25 and 50 Side-mounted
Handwheels section.
Maintenance
Because the screw threads are permanently lubricated
with a solid film lubricant, periodical lubrication is not
necessary; however, periodically examine the hand-
wheel assembly:
1. Check bearing wear by pulling on the handwheel. If
movement more than 1 /
8
-inch in any one direction is
present disassemble and inspect bearings.
2. Keep the handwheel mechanism free from dirt. If
dirt begins to impair handwheel operation, disas-
semble and clean thoroughly.
Disassembly
To disassemble the side-mounted handwheel on size
100 and 200 linear actuators, refer to Figure 2:
1. Depressurize the process line and actuator to at-
mospheric pressure. Remove the actuator from
valve (see valve’s maintenance bulletin for instruc-
tions). Disassemble cylinder by following steps 1-6
under 'Disassembling Actuator' instructions found
in IOM 2 (Cylinder Actuators).
