Replacing Handwheel or Wrenching Square with Chainwheel

6. Align the second pin hole in the actuator shaft and the pin hole in the chainwheel hub. Support

the hub of the chainwheel with a solid surface and drive the connecting pin (B2) into position.

See Figure 7 for location of connecting pin.

The connecting pin securing the chainwheel hub to the actuator shaft could potentially

shear allowing the chainwheel to disengage from the actuator shaft and cause

personal injury or equipment damage.

A retaining pin at the end of the actuator shaft must be in-place to insure the

chainwheel can not disengage from the actuator shaft.

7. Support the hub of the chainwheel with a solid surface and drive the retaining pin (B2) into the

remaining pin hole at the end of the actuator shaft.

8. Slide the collar (B7) up to the bearing (B6) and tighten with set screw (B8).

9. Feed the chain (B9) over the chainwheel (B4) and through both openings in the chain guide

(B5).

10. Connect the ends of the chain (B9) with closing link (B10).

Replacing Chainwheel with Handwheel or Wrenching Square

Refer to Figure 7 for component identification.

1. Support the chainwheel hub with a solid surface and drive out the two pins (B2).

2. .Remove the chainwheel (B4) and chain guide (B5) assembly from the actuator shaft.

3. .Loosen the set screw (B8) and slide the collar (B7) off the actuator shaft.

4. GS-12A on 14" - 20" valves only - Remove screws (B17), lockwashers (B18) and slide

adaptor (B16) off the actuator shaft.

5. Slide the handwheel (B3) or wrenching square (B11) onto the actuator shaft. Align the pin hole

in the handwheel or wrenching square with the second pin hole in the actuator shaft. Support

the actuator shaft with a solid surface and drive the pin (B2) into position.
