Removal (Fig. 94) 1. Read the General Pre<strong>caution</strong>s for Removing and Installing Hydraulic System Components at the beginning 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 hydraulic lines from manifold and put caps or plugs on open hydraulic lines and fittings. Label disconnected hydraulic lines for proper reassembly. 4. Remove hydraulic manifold from the frame using Figure 94 as guide. 5. If hydraulic fittings are to be removed from manifold, mark fitting orientation to allow correct assembly. Remove fittings from manifold and discard O--rings. Installation (Fig. 94) 1. If fittings were removed from manifold, lubricate and place new O--rings onto fittings. Install fittings into manifold openings using marks made during the removal process to properly orientate fittings. Tighten fittings (see Hydraulic Fitting Installation in the General Information section of this chapter). 2. Install hydraulic manifold to the frame using Figure 94 as guide. A. If valve plate (item 2) was removed, tighten lock nut (item 7) until washer begins to seat in isolator (item 5). Do not cause isolator to be deformed during valve plate installation. 3. Remove caps and plugs from fittings and hoses. Using labels placed during manifold removal, properly connect hydraulic lines to manifold.
