Cutting Deck Motor Removal 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 motor removal, thoroughly clean exterior of motor and fittings. 5. Remove caps or plugs from fittings and hoses. Connect hydraulic hoses to deck motor. 6. After assembly is completed, verify that hydraulic hoses and fittings are not contacted by moving components through full range of deck movement. 4 1 5 4. Disconnect hydraulic lines from deck motor. Put caps or plugs on fittings and hoses to prevent contamination. Label hydraulic lines for proper installation. 5. Remove two (2) flange head screws that secure hydraulic motor to motor mount (Fig. 78). 6. Carefully remove hydraulic motor from cutting deck taking care not to damage spider hub attached to motor. Locate and remove spider and mounting shim(s) (if present) from the deck. 7. If required, remove spider hub from motor shaft. Straighten tab washer and remove nut, spider and woodruff key. Installation 1. If spider hub was removed from motor shaft, thoroughly clean tapered surfaces of hub and shaft. Install spider hub to motor shaft with tab washer and nut. Torque nut from 27 to 33 ft -lb (37 to 45 N -m). Bend small tab of washer into keyway and large tab against nut. 2. Check for proper clearance between spider hub and spindle pulley. Install motor to cutting deck without placing the spider in the spindle pulley. The clearance between hub and pulley valleys should be from 0.830” to 0.930” (21.1 to 23.6 mm). If required, use mounting shims between motor and motor mount to adjust clearance. 3. Position spider in spindle pulley. Place mounting shim(s) (if required) on deck. Carefully install hydraulic motor to the cutting deck taking care not to damage spider hub attached to motor. 4. Secure motor to cutting deck with two (2) flange head screws (Fig. 78). IMPORTANT: For proper hydraulic hose routing, make sure cutting deck is fully lowered before installing hoses to deck motor. Groundsmaster 4100--D Page 4 - 113 1. Cutting deck motor 2.
