5 Maintenance Procedures Removal and Installation—Poly V-belt, Alternator and Air-Conditioning Compressor Drive Removal 1. Remove the poly V-belt from the fan and coolant pump drive as described in “Poly V-belt, Coolant Pump Drive and Fan Drive” “Removal”. 2. Next, place a flex-bar with a 15 mm socket on the alternator and air conditioning compressor drive belt tensioner roller fastener as shown. Move the bar in the direction shown to relieve pressure on the belt tensioner. 3. With the belt tensioner pressure relieved, remove the poly V-belt from the pulleys. 5-32 NOTE: The tensioner can be temporarily blocked with a 0.16-0.2 inch (4-5 mm) thick pin (bore). This facilitates removal and installation of the poly V-belt. 4. After removing the belt, carefully allow the belt tensioner to spring back to the stop (if it had not been temporarily blocked). 5. Inspect the pulleys for damage, rust and grease deposits. Clean or replace as necessary. Installation 1. Place the new poly V-belt over the pulleys, positioning the new belt so that it falls into all the belt pulley grooves. 2. After installing the belt, carefully allow the belt tensioner to spring back to its normal position. If the tensioner had been temporarily blocked, relieve tensioner pressure enough to remove the locking pin, then allow the tensioner to spring back to its normal position. 3. Reinstall the coolant pump and fan drive poly V-belt as previously described in “Poly V-belt, Coolant Pump Drive and Fan Drive” “Installation”. 4. Reconnect the electrical ground wire to the battery. Cleaning the Engine When cleaning the engine, follow the instructions from the vehicle manufacturer Operator’s Manual and observe all environmental protection regulations.
CAUTION: Do not direct water onto electrical components, plug connectors, seals or flexible hoses on the engine. Water may enter the part causing electrical damage or contaminating oil. To prevent damage to engine components, keep the water moving at all times while cleaning the engine. Failure to comply may result in equipment damage. Maintenance Procedures 5-33 5
