Removal 1. Park machine on a level surface, lower cutting decks, 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 the Service and Repairs section of this chapter. 3. To prevent contamination of hydraulic system during motor removal, thoroughly clean exterior of motor and fittings. NOTE: To ease reassembly, tag the hydraulic hoses to show their correct position on the axle motor. 4. Disconnect hydraulic hoses from rear axle motor. Put caps or plugs on open hydraulic lines, fittings, and ports to prevent contamination. IMPORTANT: Support axle motor to prevent motor from falling during removal. 5. Remove motor using Figure 62 as a guide. Installation 1. If removed, install pinion gear to axle motor. 2. Install o--ring onto motor. Position motor to rear axle assembly making sure that arrows on the side of motor case point upward. Align gear teeth and slide motor into place. 3. Secure motor to axle with cap screws and flat washers. Torque screws from 59 to 73 ft--lb (80 to 99 N--m). 4. Remove plugs from hydraulic lines, fittings, and ports. Attach hydraulic hoses to axle motor. 5. Fill reservoir with hydraulic fluid as required (see Operator’s Manual). 6. After assembly is completed, verify that hydraulic hoses and fittings do not contact anything through full range of axle pivot motion. Also, check for any leaks.
