Removal (Fig. 64) 1. Park machine on a level surface, lower cutting deck, stop engine, engage parking brake and remove key from the ignition switch. 2. Read the General Pre<strong>caution</strong>s for Removing and Installing Hydraulic System Components at the beginning of this section. 3. To prevent contamination of hydraulic system during steering valve removal, thoroughly clean exterior of steering valve and fittings. Installation (Fig. 64) 1. If fittings were removed from steering valve, lubricate and place new O--rings onto fittings. Install fittings into port 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 steering valve using Figure 64 as a guide. 3. Make sure hydraulic tank is full. Add correct oil if necessary before returning machine to service. 4. Remove steering valve from machine using Figure 64 as a guide. 5. If hydraulic fittings are to be removed from steering valve, mark fitting orientation to allow correct assembly. Remove fittings from valve and discard O--rings.
