Section 3: Actuator Reassembly
Actuator Reassembly
3.6.20
Install cover (20 - 10 - 140) onto the manifold (20 - 10 - 10) with soc cap
screws (25 - 240).
3.6.21
Install instruction tag (25 - 220) onto the cover (20 - 10 - 140).
3.6.22
Engage quick rel. pin (20 - 10 - 110) with the pump handle lever (20 - 10 - 90).
3.6.23
Install acorn nut (25 - 450), lock washer (25 - 460), control knob (25 - 200) and
control pointer (25 - 150) onto stem, control valve (20 - 10 - 280). Note orientation
of knob and control pointer.
3.6.24
Install manifold (20 - 10 - 10) onto the mounting bracket (30 - 90) with csk cap
screws (30 - 100).
3.6.25
Install mounting bracket (30 - 90) onto the actuator with soc hd cap screw
(30 - 110) and lock washer (30 - 120).
3.6.26
Fill up reservoir (10) with hydraulic fluid, note for the G7 and above sizes, only half
way is needed to prevent reservoir overflow during potential spring return.
3.6.27
Shift the control knob (25 - 200) to proper port location to operate.
3.6.28
Operate pump handle lever (20 - 10 - 90) for few cycles to move the hydraulic
fluid into the manifold (20 - 10 - 10). Leave the pump handle lever at the
uppermost location.
3.6.29
Disengage the quick rel. pin (20 - 10 - 110) from the pump rod (20 - 10 - 50).
3.6.30
Use 13/16 size wrench to hold the pump rod (20 - 10 - 50) from turning while
loosening the pipe plug (20 - 10 - 210) with 3/16 hex wrench. Note pipe plug does
not need to be removed, only loosened so air can escape.
3.6.31
Gently lower the pump rod (20 - 50) until all the air is vented out, reengage the
quick rel. pin (20 - 10 - 110) in order to pump handle lever (20 - 10 - 90) for few
more cycles until all the hydraulic fluid is filled in the pump system. One shall feel
the proper fill during the full stroke of pump cycling.
3.6.32
Disengage the quick rel. pin (20 - 10 - 110), apply pipe dope or blue Loctite 242
onto the thread of the pipe plug (20 - 10 - 210).
3.6.33
Use 13/16 size wrench to hold the pump rod (20 - 10 - 50) from turning while
tightening the pipe plug (20 - 10 - 210) with 3/16 hex wrench.

M18 Reservoir Reassembly
3.7.1
Lube up and install seal O-ring (10 - 100) onto the end cap, bottom (10 - 40).
3.7.2
Install end cap, bottom (10 - 40) from the bottom side of the reservoir cylinder
(10 - 20), note the orientation of the end cap to be in alignment with the piping.
3.7.3
Lube up and install seal O-ring (10 - 100) onto the end cap, upper (10 - 10).
3.7.4
Install end cap, upper (10 - 10) from the top side of the reservoir cylinder (10 - 20),
note the orientation of the breather (10 - 90) to be in the opposite side to where
the piping goes into the end cap, bottom (10 - 40).
3.7.5
Install thread seal (10 - 70), counter sink washer (10 - 60) and acorn nut (10 - 50)
onto the center bar (10 - 30).
3.7.6
Install all the piping from the M18 override manifold (20 - 10 - 10) to the actuator
and reservoir (10).
