Removal (Fig. 76)
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 prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of manifold
and fittings.
3. Disconnect wire harness connector from the sole-
noid valve coil on the traction manifold.
4. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper reassembly.
5. Remove traction manifold from the frame using Fig-
ure 76 as a 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. 76)
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. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Install traction manifold to the frame using Figure 76
as a guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con-
necthydraulic 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 coil on the traction manifold.
5. Make sure hydraulic tankis full. Add correctoil if nec-
essary before returning machine to service.
