A loose belt will also result in premature belt wear. C Figure 5-9: Forward clutch belt. (C, Left- side view, no belt cover.) • Check belt tension after the first two hours of break-in operation and after every 10 operating hours. • At the end of each tilling season, check the belt for cracks, cuts or frayed edges. A belt in poor condition should be replaced. 2-1/2" extended spring length Figure 5-10: Correct spring length whenForward Clutch Levers are engaged is 2-1/2". Checking Forward Belt Tension 1. Before checking, shut off engine, allow the engine and muffler to cool down, disconnect the spark plug wire, remove the ignition key on electric start models. 2. The coiled part of the forward clutch spring (E, Figure 5-9) measures 2" in length when the Forward Clutch Control levers are not pulled up. Pull either Forward Clutch Control Lever up against the handlebar and measure the length of the coiled part of the forward clutch spring. Tension is correct if the length of the extended coil is 2-1/2" (see Figure 5-10). The forward clutch cable needs adjustment if length of the extended coils is less than 2-1/2". See Adjusting the Forward Clutch Belt for a procedure. If the extended length is more than 2-1/2", there is no need to adjust as long as the unit operates correctly when moving Forward. E F Figure 5-11: Location of forward clutch cable spring (E) and forward cable adjuster (F). Adjusting the Forward Clutch Cable Do this procedure if the forward clutch spring measurement is not correct (see Checking Forward Belt Tension) 1. Before adjusting the belt, shut off engine, allow the engine and muffler to cool down, disconnect the spark plug wire, and remove the ignition key on electric start models. 20 Section 5: Maintenance Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, remove ignition key on electric start models, disconnect spark plug wire and move wire away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage. WARNING 2. Belt adjustments are done with the forward clutch cable adjuster (F, Figure 5-11). Use two 1/2", open-end wrenches to loosen the two jam nuts (A, Figure 512) a few turns. 3. Move cable adjuster (B, Figure 5-12) downward for more belt tension (see Figure 5-12). 4. Hand tighten the jam nuts and pull the Forward Clutch Control levers up against the handlebar. Measure the coiled part of the spring (Figure 5-10). The length of the extended coil should be 2-1/2".

FORWARD CLUTCH BELT REMOVAL AND INSTALLATION NOTE: The photographs in this Section show a reverse drive assembly (pulley, A, Figure 5-8), belt (B), cable (C) and linkage(D). These components are not used on Model 12226. The forward clutch belt (K, Figure 5-14) engages the engine pulley (I) and the transmission pulley (J) when either Forward Clutch Control Lever is pulled up against the handlebar. The lever draws the forward clutch cable (G) tight, which causes the forward clutch idler pulley (H) to apply pressure to the forward clutch belt. This causes the pulleys to turn for Forward movement. 1. Stop engine, allow it to cool and disconnect spark plug wire before working near belts. Also remove ignition key on electric start models. 2. Remove the belt cover by removing the two nuts (C, Figure 5-13). 3. Disconnect the forward clutch cable from the forward clutch idler arm bracket (Figure 5-15). Note the hole from which you disconnect the cable. It is important that you reconnect the cable to the same hole. 4. Slide the belt off the engine pulley (C, Figure 5-16), away from engine, out from under the belt guide (D), and completely off the pulley. 5. Slip the belt off the front of the transmission pulley (F, Figure 5-17). 6. Work the belt out from between the pulley and th...
