Replacing Handwheel or Wrenching Square with

Chainwheel

Refer to Figure 7 for component identification.

1. Support the actuator shaft with a solid surface, drive out the pin (B2), and remove the

handwheel (B3) or wrenching square (B11) from the actuator shaft.

2. Slide the collar (B7) onto the actuator shaft

3. Assemble the bearing (B6), chain guide (B5) and the chainwheel (B4) onto the actuator shaft.

4. 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.

5. 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. See Figure 7 for location of retaining pin.

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

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

(B5).

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

1. Support the actuator shaft with a solid surface, drive out the pin (B2), and remove the

handwheel (B3) or wrenching square (B11) from the actuator shaft.

2. Remove the plastic plugs from the mounting holes on the shaft side of the actuator housing.

3. Slide the adaptor (B16) onto the actuator shaft. Tighten with screws (B17) and lockwashers

(B18).

4. Slide the collar (B7) onto the actuator shaft

5. Assemble the bearing (B6), chain guide (B5) and the chainwheel (B4) onto the actuator shaft.
