PC control
1. Clean all control parts and cover with a light coating of hydraulic fluid prior to reassembly.
2. Install the spherical end of the PC spool (C132) into the PC bore (refer to illustration). Install the PC
plug (C103) using a new O-ring (C103A). Torque at 10.8 to 13.5 N•m [8 to 10 lbf•ft].
3. Place the two PC springs (C134, C135) onto the PC spring guide (C133) and install into the PC bore.
Place a new O-ring onto the PC plug and install it so that it sits one turn below the surface of the
control housing. Install and tighten set screw (C102) at 7.5 to 10.8 N•m [5.5 to 8.0 lbf•ft] to retain the
adjusting plug.

LS control (optional)
Install the PC portion as described in
1. Hold the control in a horizontal position. Install the spherical end of the LS spool (C112) into the LS
bore (see illustration). Using a new O-ring, install the LS plug (C104), torque at 10.8 to 13.5 N•m [8 to
10 lbf•ft].
2. Place the 2 LS springs (C114, C115) onto the LS spring guide (C113) and install into the LS bore. Place
a new O-ring (C116) and back-up rings (C117) onto the LS adjustment screw (C118). Install the LS plug
assembly so that it sits one turn below the surface of the control housing.
3. Install and tighten set screw (C102) at 7.5 to 10.8 N•m [5.5 to 8.0 lbf•ft]. Also, install the plugs (C105,
C106) with new O-rings. Torque the plugs at 10.8 to 13.5 N•m [8 to 10 lbf•ft].
PC and LS spools need to be adjusted to proper setting according to tag nomenclature.
