•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 41.

BRAKE ADJUSTMENT
Moderate brake pedal play, as measured at the end of the pedals, ranges from 0.98 to 1.57 inches (25 to 40 mm). If the brake pedals need adjustment, proceed as follows:
•Loosen the jam nuts from the turnbuckle on both the left and right brake adjustment rods. See Figure 42.
•Turn the turnbuckle on each rod until both the right and left brake pedals are within the acceptable range of play. See Figure 42.
•Tighten the jam nuts after adjusting the turnbuckles.
•Interlock and depress both brake pedals and check that the parking brake engages properly.

CLUTCH ADJUSTMENT
Moderate clutch pedal play ranges from 1.57 to 1.96 inches (40 to 50 mm) 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 43.

IMPORTANT: Free travel of the clutch pedal is governed by the clearance between the clutch’s release thrust bearing and the release levers. This clearance is set from 0.098 to 0.12 inches (2.5 to 3
mm)when the tractor is built, but this changes as the tractor is used. If the pedal is used with no clearance, it will result in the seizure of the release bearing or wear of the facing. Therefore, be sure to check and adjust at the intervals called for in the maintenance schedule.
