Section 3: Actuator Reassembly
Actuator Reassembly
NOTE:
The guide bar bearing (2-20) must be pressed t into guide block guide bar bore with the
seam located 45 ±5 degrees of the top or bottom centerline as shown in section A-A.
For G01 model actuators skip steps 3.2.2 through 3.2.13 and continue reassembly at step 3.2.14.
3�2�2 Lubricate guide block (1-30), two spherical washers (1-40), and one extension rod
assembly (1-50).
3�2�3 Install one spherical washer (1-40) into the side of guide block (1-30).
NOTE:
The spherical side of washer (1-40) will be facing the outside of guide block (1-30).
3�2�4 Install second spherical washer (1-40) over threaded end of extension rod
assembly (1-50).
NOTE:
The spherical side of the washer will go on the extension rod assembly facing the head of
the extension rod assembly.
3�2�5 Install extension rod assembly (1-50) into guide block (1-30) and up against the
rst spherical washer (1-40).
3�2�6 Install extension retainer nut (1-60) over extension rod assembly (1-50) and screw
into guide block (1-30).
3�2�7 Tighten extension retainer nut assembly (1-60) until extension rod assembly
(1-50) is immovable. Back off the extension retainer nut assembly (1-60) just
enough to allow for extension rod assembly (1-50) to move freely.
NOTE:
Steps 3.2.8 through 3.2.13 are to be completed when the actuator is equipped with a
spring module. If the actuator is double-acting then skip steps 3.2.8 through 3.2.13 and
continue actuator reassembly starting with step 3.2.14.
3�2�8 Lubricate guide block (1-30), two spherical washers (9-40) and one extension rod
assembly (9-50).
3�2�9 Install one spherical washer (9-40) into the side of guide block (1-30).
NOTE:
The spherical side of washer (9-40) will be facing the outside of guide block (1-30).
3�2�10 Install second spherical washer (9-40) over threaded end of extension rod
assembly (9-50).
