THREE SPEED TRANSMISSION Removal - Toro Vacu Power/Lawn-Boy Medallion Models Complete transmission removal on the Toro Vacu Power/Lawn-Boy Medallion mower is quite easy and is recommended for most self-propel system repairs. 1. Remove the spark plug lead from the engine to prevent accidental starting. Drain the fuel and oil. 2. Place the ground speed selector in neutral. This will make it easier to remove the speed selection cable later. 3. Remove the two flanged head self-tapping screws securing the screen panel to the housing and remove the panel (Fig. 118). 4. Remove the black plastic transmission cover from the top rear of the housing. 5. Remove the two flanged head self-tapping screws securing the belt cover to the top of the transmission. Pull the cable from belt guide and remove the belt guide. 6. Remove the transmission access cover from the rear of the housing by pressing from underneath. 7. Loosen the gear selection control cable clamp screw until the cable comes free. Do not attempt to remove the gear selection cable from the control arm at this time. 8. Turn the mower onto its right side and remove the four flanged head self-tapping screws securing the end caps to the housing (Fig. 119). A C A. Screen panel B. Screws Fig 118 fig 94 C.
