7. Remove the belts from the crankshaft pulley grooves and pull out from behind the clutch. Pump Drive Belt Replacement 1. Place the belts under clutch into the crankshaft pulley grooves. 2. Wrap the belts around the top side of the idler arm pulley and install the belts in the right-hand pump pulley grooves. 3. Reinstall the spring onto the anchor bolt on the idler arm. 4. Carefully rotate the idler arm with the breaker bar counter-clockwise (see Figure 49). While holding the breaker bar firmly, install the belts in the left- hand pump pulley grooves and the two stationary idler pulleys grooves. 5. Carefully release the tension on the breaker bar. 6. Inspect the belt path making sure that all belts are properly seated in the pulley grooves. 7. Reinstall the PTO drive belt from the clutch (see PTODRIVE BELTREPLACEMENTfor instructions). A B Figure 49. Pump Belt Removal & Replacement A. Pump Drive Idler Arm B. Spring To avoid damaging belts, DO NOT PRY BELTS OVER PULLEYS. WARNING Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension. 48 Troubleshooting, Adjustment & Service PTO Drive Belt Removal 1. Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. 2. Release the hood cam latches and raise the hood until it locks in place. 3. Release the rear guard cam latches and lower or remove the rear guard. 4. Using a 3/4” box end wrench on the nut of the spring-loaded idler pulley (A, Figure 50), rotate the wrench CLOCKWISE to release the tension on the PTO drive belt. WARNING Use extreme caution when rotating the idler pulley with the wrench, due to the increased tension in the spring as the idler pulley is being rotated. Injury may result if the wrench is prematurely released while the spring is under tension. 5. Remove the belt from the stationary idler pulley (B, Figure 50). 6. Carefully release the tension on the wrench. 7. Remove the belt from the PTO clutch pulley, spring-loaded idler pulley and center spindle pulley. 8. Pull the belt towards the rear of the machine until free of the guide pulleys and belt keeps on the rear of the mower deck. PTO Drive Belt Replacement 1. From the rear of the mower deck, route the new belt through the guide pulleys and belt keeps. 2. Install the belt on the center spindle pulley. Follow the illustration in Figure 51 carefully. Make sure the belt twists in the correct direction. 3. Install the belt over the PTO clutch pulley and the spring loaded idler pulley. Again, follow the illustration in Figure 51 carefully and make sure the belt twists in the correct direction. 4. Using a 3/4” box end wrench on the nut of the idler pulley (A, Figure 50), rotate the wrench CLOCKWISE and install the belt on the stationary idler pulley. 5. Carefully release the tension on the wrench. A B Figure 50. PTO Drive Belt Removal A. Spring Loaded Idler Pulley B. Stationary Idler Pulley Spindle Drive Belt Removal & Replacement 1. Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. 2. Remove the PTO drive belt from the center spindle pulley (see PTODRIVE BELTREMOVAL for instructions). 3. Using a 1/2” breaker bar, place the square end in the square hole located near the end of the idler arm (A, Figures 52). Carefully rotate the breaker bar CLOCKWISE, which will relieve the tension on the belts exerted from the idler arm. WARNING Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension. 4. Remove the belt from the trim side spindle pulley (B, Figure 52). 5. Carefully release the tension on the breaker bar. 6. Remove the old belt and replace with a new one. Make sure the V-side of the belt runs in the pulley grooves (Figure 53). 7. Install the belt on all of the pulleys, except for the trim side spindle pulley. Carefully rotate the breaker bar CLOCKWISE and install the belt on the trim side spindle pulley. Carefully release the tension on the breaker bar. 8. Reinstall the PTO drive belt. Troubleshooting 49 Troubleshooting, Adjustment & Service Figure 51.
