Section 2: Actuator Disassembly
Actuator Disassembly
NOTE:
Piston (3 - 30) acts as the retainer for inboard split ring halves (3 - 50). When removing the
piston be careful to not lose inboard split ring halves (3 - 50).
2.2.7.2 Remove piston (3 - 30) and two split ring halves (3 - 50) from piston
rod (3 - 40).
NOTE:
Steps 2.2.8 is used only on early G2 and G3 models equipped with outboard and inboard tie
bar nuts.
2.2.8 Remove early model G2 and G3 pistons as follows:
2.2.8.1 Refer to assembly drawing page 2 of 2 Detail "D". Remove two split ring
halves (3 - 50) and one retainer ring (3 - 60) from inboard side of
piston (3 - 30).
NOTE:
Piston (3 - 30) acts as the retainer for outboard split ring halves (3 - 50).
2.2.8.2 Slide piston (3 - 30) toward the inner end cap (3 - 10) until the out board
split ring halves is exposed enough for removal. Remove outboard split
ring halves from piston rod (3 - 40).
2.2.8.3 Remove piston (3 - 30) and two split ring halves (3 - 50) from piston
rod (3 - 40).
2.2.9 Remove O-ring seal (4 - 70) from piston rod (3 - 40).
2.2.10 Remove hex cap screws (3 - 100) with lock washers (3 - 110) from housing (1 - 10).
2.2.11 Remove inner end cap (3 - 10) off of piston rod (3 - 40).
NOTE:
On early model G2 and G3 actuators remove two hex nuts (3 - 90) from housing (1 - 10).
These two nuts will be loose after tie bars (3 - 20) are removed in step 2.2.6.1 and will be
located in the area where the piston rod passes through the housing (1 - 10).
NOTE:
The piston rod (3 - 40) removal as outlined in step 2.2.12 is only required when the piston
rod is being replaced or when the drive module is to be disassembled.
2.2.12 Unscrew and remove piston rod (3 - 40) from drive module.
