•Tighten the adjusting bolt as necessary to remove the play from the front axle, then retighten the jam nut.

•Lower the front of the tractor to the ground.

ADJUSTING THE FAN BELT TENSION

If the fan belt becomes loose, the engine may overheat and/or the battery may not charge. Check the belt tension and, if necessary, adjust as follows:

•With approximately 22 lbs. of pressure, depress the backside of the belt at its center point between the alternator and lower engine pulley. The deflection of the belt should be approximately 0.3 inches. See Figure 43.

•If adjustment is needed, loosen the nut on the alternator mounting bolt and loosen the adjusting bolt. See Figure 43.

•Pivot the alternator to acquire the correct belt tension and re-tighten the adjusting screw and mounting fasteners.

CLUTCH ADJUSTMENT

Moderate clutch pedal play ranges from 0.79 to 1.18 inches (20 to 30mm) as measured at the end of the pedal. If it becomes difficult to disengage the clutch or pedal play decreases, adjust the length of the clutch rod. From inside the left side panel, remove the internal cotter pin and clevis pin to disconnect the clutch rod. If the clutch is difficult to disengage, shorten the rod. If there is too little play in the clutch pedal, lengthen the rod. See Figure 44.

•Turn the turnbuckle on each rod until both the right and left brake pedals are within the acceptable range of play.

•Tighten the jam nuts after adjusting the turnbuckles.

•Interlock and depress both brake pedals and check that the parking brake engages properly.
