Actuator Reassembly
NOTE:
The guide bar bearing (2-20) must be pressed fit 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
first 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
