washer for reassembly.
c. Remove handle from stem. Save for reassembly.
Pneumatic actuator:
a. Remove cotter pin from pivot pin, located behind the clevis, and
save for reassembly. Remove the pivot pin and washers. Save
parts for reassembly.
b. To remove crank arm, first remove cotter pin from crank arm and
discard. Rotate the crank arm counterclockwise until the leg
clears the clevis. Pull the crank arm off the stem. Remove nylon
washer. Retain all parts.
c. Remove and retain bracket screws and bracket lock washers.
The actuator bracket can now be removed and saved.
2. Using a 1 3 /8" wrench, completely loosen and carefully remove the
