Relief Valve Removal 1. Park machine on a level surface, stop engine, engage parking brake, and remove key from the ignition switch. CAUTION Rotate steering wheel and depress traction pedal in both forward and reverse to relieve hydraulic system pressure and to avoid injury from pressurized hydraulic oil. 2. Operate all hydraulic controls to relieve hydraulic system pressure. 3. Read the General Precautions for Removing and Installing Hydraulic System Components at the beginning of the Service and Repairs section of this chapter. 4. Disconnect hose assembly from hydraulic fitting at bottom of relief valve body. Allow hose to drain into a suitable container. 5. Unscrew relief valve body from hydraulic adapter in side of piston pump. 6. If needed, remove hydraulic fitting from bottom of relief valve body. Installation 1. Lubricate new o–rings with clean hydraulic fluid. A. Contamination may cause valves to stick or hang up. Contamination can become lodged in small valve orifices or seal areas causing malfunction. B. If sealing surfaces appear pitted or damaged, the hydraulic system may be over heating or there may be water in the hydraulic system. CAUTION Use eye protection such as goggles when using compressed air. 4. Clean relief valve cartridge using clean mineral spirits to flush out any contamination. Submerge cartridge in clean mineral spirits to flush out contamination. Particles as fine as talcum powder can affect the operation of relief valve. Use compressed air for cleaning. Reassembly 1. Lubricate new o–ring and back–up ring with clean hydraulic fluid. Install o–ring and back–up ring to the relief valve cartridge. 2. Carefully thread relief valve cartridge into the relief valve body. The valve should go in easily without binding. Torque cartridge to 190 in–lb (21.4 N–m). 3. Lubricate new O–rings with clean hydraulic fluid. Connect hydraulic fittings and O–rings to the relief valve body. Hydraulic System 2. If removed, install hydraulic fitting into bottom of relief valve body. 3 5 6 3. Secure valve body to the hydraulic adapter in side of piston pump. 4. Install hydraulic hose to hydraulic fitting at bottom of relief valve body. Tighten hose connections.
