caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper reassembly.
5. Remove hydraulic manifold from the frame using
Figure 75 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. 75)
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 hydraulic manifold to the frame using Figure
75 as guide.
3. Remove caps and plugs from fittings and hoses. Us-
