Actuator Reassembly
3.6.6 Install pump cyl (20 - 10 - 20) and the pin, cyl (20 - 10 - 60) into the manifold
(20 - 10 - 10), note the orientation of the pump cylinder.
3.6.7 Install retnr ring (20 - 10 - 80) into the manifold to secure the pin, cyl (20 - 10 - 60).
3.6.8 Lubricate pump rod (20 - 10 - 50) with hydraulic uid, gently install it into the
pump cyl (20 - 10 - 20), note to orient it correctly.
3.6.9 Lubricate stem, cntrl vlv (20 - 10 - 280) with hydraulic uid, install seal O-ring
(20 - 20 - 40) and backup ring (20 - 20 - 50) onto the stem. Note the location of
O-ring and backup ring.
3.6.10 Lubricate pstn, cntrl vlv (20 - 10 - 310) with hydraulic uid, install seal O-ring
(20 - 20 - 110) and backup ring (20 - 20 - 120) onto the piston. Note the location of
O-ring and backup ring.
3.6.11 Lubricate back plt, cntrl vlv (20 - 10 - 320), seal o-ring (20 - 20 - 90) and backup
ring (20 - 20 - 100) with hydraulic uid.
3.6.12 Install seal O-ring (20 - 20 - 90) and backup ring (20 - 20 - 100) onto the back plate.
Note the location of O-ring and backup ring.
3.6.13 Lubricate seal o-ring (20 - 20 - 40) and install onto the manifold (20 - 10 - 10)
control valve opening. Make sure the O-ring is properly installed in its place.
3.6.14 Install disc, cntrl vlv (20 - 10 - 290) onto the manifold (20 - 10 - 10) control
valve opening.
3.6.15 Apply blue Loctite 242 sparingly on the scr, t hd (20 - 10 - 330) thread and install
the disc, cntrl vlv (20 - 10 - 290) onto the manifold (20-10-10).
3.6.16 Install stem, cntrl vlv (20 - 10 - 280) together with rotor, cntrl vlv (20 - 10 - 300)
and spg pin (20 - 10 - 340) into the manifold (20 - 10 - 10).
!
CAUTION
Install rotor at correct orientation.
3.6.17 With the stem standing out from manifold assemble facing down, install thrst brg
(20 - 10 - 370), wshr, brg (20 - 10 - 380) pstn, cntrl vlv (20 - 10 - 310), spring
(20 - 10 - 390) together with back plt, cntrl vlv (20 - 10 - 320) into the
manifold (20 - 10 - 10).
NOTE:
The seal friction from the back plate should be able to hold against the spring
tension applied.
3.6.18 Install back brace (20 - 10 - 130) onto the manifold (20 - 10 - 10) with soc hd cap
screws (20 - 10 - 100).
3.6.19 Install ball (20 - 10 - 350), spring (20 - 10 - 360) and pipe plug (20 - 10 - 210)
onto the manifold (20 - 10 - 10), the tension from the spring should engage the
rotor assembly.
