NOTE: The parts and seals used in the actuator will be assembled using lubricant as identified in
section 1 step 1.6.1.
3.1.5 For Spring Module Installation refer to Section 5 step 5.2.
3.2 DRIVE MODULE REASSEMBLY
NOTE: Review section 3.1 General Reassembly before proceeding with Drive Module
Reassembly.
NOTE: Refer to assembly drawing page 2 of 2 Detail "B" for section drawing of guide block.
3.2.1 If guide bar bearing (2-20) is being replaced install new bearing into guide block (1-30).
NOTE: The guide bar bearing (2-20) must be pressed into guide block guide bar bore with the
seam located ±5° degrees of the top or bottom centerline as shown in section A-A.
NOTE: 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 to 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 assembly (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) can not
move. 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 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 to the outside of guide block (1-30).
