Reassembly
13. Install the PC spool (C132), spherical end first,
into the PC bore. Using a new O-ring (C103A),
install the plug (C103). Torque the plug (C103)
to 10.8 - 13.5 N•m [8 - 10 lbf•ft].
14. Place the two PC springs (C134, C135) onto the
spring guide (C133) and install into the PC
bore. Place a new O-ring (C138A) onto the PC
adjusting screw and thread it into the PC bore
until flush, then make another full turn. Install
and torque the PC set screw (C102) to
7.5 - 10.8 N•m [5.5-8 lbf•ft].
For PC only controls, skip steps 15 through 17.
15. Install the LS spool (C112), spherical end first,
into the LS bore. Using a new O-ring (C105A
or C106A), install the plug (C105 or C106).
Torque the plug (C105 or C106) to
10.8 - 13.5 N•m [8 - 10 lbf•ft].
16. Using a new O-ring (C104A), install the plug
(C104). Torque the plug to 10.8 - 13.5 N•m
[8 - 10 lbf•ft].
17. Place the two LS springs (C114, C115) onto the
spring guide (C113) and install into the LS
bore. Place a new O-ring (C118A) and back-up
rings (C118B) onto the LS adjusting screw and
thread it into the LS bore until flush, then
make another full turn. Install and torque the
LS set screw (C102) to 7.5 - 10.8 N•m
[5.5-8 lbf•ft]
18. Using petroleum jelly to retain them, install
the 4 interface O-rings (C200) in the recesses
on the control housing.
19. Install the control assembly onto the endcap using the 4 screws (C300). Torque the screws to 5.4
- 7.5 N•m [4 - 5.5 lbf•ft]. Torque screws in a criss-cross pattern and re-torque the first screw to
ensure proper torque retention.
20. Check and adjust the control setting. See
