Removal (Fig. 60)
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this chapter.
2. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of HI/LOW
range control manifold.
3. Label all hydraulic lines for assembly purposes.
4. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings.
5. Remove HI/LOW range control manifold from the
frame.
6. If hydraulic fittings are to be removed from control
manifold, mark fitting orientation to allow correct as-
sembly. Remove fittings from manifold and discard O-
rings.
Manifold Service
For cartridge valve service procedures, see Control
Manifold Cartridge Valve Service in this chapter. Refer
to Figure 61 for cartridge valve and hydraulic fitting
installation torque.
NOTE: The check valve adapter used in the HI/LOW
range manifold allows free flow toward the manifold and
prevents flow away from the manifold (Fig. 62).
Installation (Fig. 60)
1. If fittings were removed from manifold, lubricate and
place new O- rings onto fittings. Install fittings into man-
ifold ports using marks made during the removal pro-
cess to properly orientate fittings. Tighten fittings (see
Hydraulic Fitting Installation in the General Information
section of this chapter).
2. Install HI/LOW range manifold to the frame.
3. Remove caps and plugs from fittings and hydraulic
lines. Using labels placed during manifold removal,
properly connect hydraulic lines to manifold (see Hy-
draulic Hose and Tube Installation in this chapter).
4. Fill hydraulic reservoir with hydraulic fluid as re-
quired (see traction unit Operator’s Manual).
