Removal (Fig. 61)
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
2. To preventcontamination ofhydraulic system during
manifold removal, thoroughly clean exterior of manifold
and fittings.
3. Disconnect wire harness connector from the sole-
noid valve.
4. Disconnect all hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings to pre-
vent system contamination. Label disconnected hy-
draulic lines for proper assembly.
5. Remove hydraulic manifold from the frame using
Figure 61 as guide.
6. If hydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move fittings from manifold and discard O--rings.
Installation (Fig. 61)
1. If fittings were removed from manifold, lubricate and
place new O--rings onto fittings. Install fittings into man-
ifold openings using marks made during the removal
process to properly orientate fittings. Refer to Figure 62
for straight fitting installation torque. For information on
tighteningproceduresforothermanifoldfittings, see Hy-
draulic Fitting Installation in the General Information
section of this chapter.
2. Install traction control manifold to the frame using
Figure 61 as guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during removal, properly connect hy-
draulic lines to manifold (see Hydraulic Hose and Tube
Installation in the General Information section of this
chapter).
4. Connect wire harness connector to the solenoid
valve.
5. Make sure hydraulic tankis full. Add correct oilifnec-
essary.
