Removal (Fig. 84)
1. Park machine on a level surface, set brake, lower
cuttingunitsandstopengine.Removekeyfromtheigni-
tion switch.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components in
this section.
2. Remove leak detector tank (see Leak Detector Re-
moval in this section).
3. Clean junction of tank hose (item 22) at solenoid
valvefitting (item21).Loosenhoseclamp (item19)and
disconnect tank hose at solenoid valve fitting.
4. Unplug machine wire harness connector from the
solenoid valve connector.
5. Removetwo(2)capscrews(item23)andlockwash-
ers(item24)thatsecuresolenoidvalveassemblytohy-
draulic reservoir.
6. Remove solenoid valve assembly from machine.
7. If necessary, remove fittings from solenoid valve
manifold. Discard removed O--rings.
Manifold Service
1. Disassemblesolenoid valvemanifoldasneededus-
ing Figure 85 as a guide.
2. For cartridge valve service procedures, see Control
Manifold Cartridge Valve Service in this section.
A. When installing cartridge valve, torque valve 35
ft--lb (47 N--m).
B. Wheninstallingsolenoidcoil,applyadropofLoc-
tite #242 (or equivalent) to threads of valve and
torque nut 10 in--lb (1.1 N--m).
Installation (Fig. 84)
1. If fittings were removed from solenoid valve man-
ifold, lubricate and place new O--rings onto fittings.
Install fittings into manifold openings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter). Torque fittings from 40
to 50 ft--lb (55 to 67 N--m).
2. Apply antiseize lubricant to the end threads of the
two (2) cap screws used to secure s olenoid valve as-
sembly to hydraulic reservoir.
3. Position cover (item 17) and solenoid valve assem-
bly to hydraulic reservoir. Orientate the solenoid valve
assemblyso thesolenoidcoil iscloser tothefront ofthe
reservoir.
4. Secure solenoid valve assembly to hydraulic reser-
voir withtwo (2) capscrews(item 23) and lockwashers
(item24).Torquecapscrewsfrom30 to 60 in--lb(3.4to
6.7 N--m).
5. Connect tank hose (item22) to solenoid valve fitting
(item 21) and secure with hose clamp (item 19).
6. Installleakdetectortank(seeLeakDetectorInstalla-
tion in this section).
