Changing Actuator Mounting; Changing Styles - Fisher 1061 Instruction Manual

1061 H & J Actuator
January 2016
Then, replace the cover (key 34) and secure it with the cap screws and washers (key 35 and 76). If the holes in the
cover and housing do not align, temporarily loosen the cap screws (key 24) and shift the housing slightly. Tighten
the cap screws to the torque value listed in table 7.
b. If the actuator is equipped with a manual handwheel actuator, refer to the separate instruction manual for
mounting instructions.
17. Follow the instructions in the Actuator Mounting portion of the Installation section for correct actuator mounting
and adjustment. Remember to replace the access plate (key 72) when performing these procedures.

Changing Actuator Mounting

The actuator is normally positioned vertically in a horizontal pipeline. However, there are two possible mounting styles
and four possible positions for each style (see figure 4). Key numbers referenced in the following procedures are
shown in figure 6 unless otherwise specified.
WARNING
Perform the steps in the WARNING at the beginning of the Maintenance section.
Use the following procedures along with figure 6 for key number references to convert from style A to style B or
vice‐versa or to change the mounting position.

Changing Styles

1. Unscrew the cap screws and washers (key 35 and 76), and remove the cover (key 34). If an optional manual
handwheel actuator is used, it will be removed with the cover.
2. Heat the hex nut (key 14) to 177_C (350_F) long enough for the thread locking adhesive (medium strength) (key
92) to lose its holding strength. Then, remove the cap screw and hex nut (keys 13 and 14).
3. Loosen the cap screw (key 29).
CAUTION
Do not use a hammer or similar tool to drive the lever (key 28) off the output shaft. Driving the lever could damage
operated equipment. For valves, driving the lever could move the valve disk and bearings away from the centered position
causing subsequent damage to valve parts.
If necessary, use a wheel puller to remove the lever. It is permissible to tap the wheel puller screw lightly to loosen the
lever, but hitting the screw with excessive force could damage the operated equipment.
4. Mark the side of the lever (key 28) that is nearest to the end of the output shaft (key 94). This marking is used during
reassembly to determine which side of the lever should be inserted into the actuator housing first. When the lever is
marked, remove the lever.
5. For an actuator with a J mounting adaptation,
a. Unscrew the cap screws (key 24), and remove the actuator housing (key 21) from the mounting yoke (key 23).
b. Rotate the actuator housing 180 degrees, maintaining the appropriate position (1, 2, 3, or 4), and place the
actuator onto the mounting yoke (key 23).
