2. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of filter
manifold and fittings.
3. Disconnect hydraulic lines from filter manifold and
putcapsor plugs on openhydrauliclinesand fittings. La-
bel disconnected hydraulic lines for proper reassembly.
4. Remove filter manifold from the frame using Figure

move fittings from manifold and discard O--rings.
Installation (Fig. 78)
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 filter manifold to the frame using Figure 78 as
a guide.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con-
