NOTE :
• When making adjustments, park the tractor
on flat ground and apply the parking brake.
10.1 Fan drive belt tention
If the fan drive belt becomes loose, the engine
may overheat. Check the belt tension as shown
b e l o w.
To adjust, loosen the adjusting bolt and tighten the
tension bolt to stretch the belt. After adjustment,
securely tighten the adjusting bolt.
Moderate belt tension :
The belt sould be approx. 8mm(0.3 in.) when the
center of the belt is depressed with a finger
presssure of 98N(10kgf, 22lbs).

10.2.1 Clutch

Moderate clutch play ranges from 40 to 50
mm(1.57 to 1.96 in.).
If the clutch becomes difficult to disengage or
pedal play decreases, adjust the length of the
clutch rod after removing the pin. When the clutch
is difficult to disengage, shorten the rod. When the
clutch play is too little, extend the rod.
- Adjustment of Clutch Pedal Free Tr a v e l
I M P O RTANT :
• Free travel of the clutch pedal is governed by the
clearance of release thrust ball bearing to the
release levers. This clearance is set from 0.098
to 0.12 in.(2.5 to 3mm) when the tractor leaves
the factory, but this changes with use. If the pedal
should be 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
each periodical maintenance service.
- To Adjust
1. Open the clutch access window which is located
on the right hand forward of the clutch housing.
2. Insert a 0.098 to 0.12 in.(2.5 to 3.0mm)
thickness gauge between the release thrust ball
bearing and the release levers. Adjust the
clearance by the length of the clutch rod.
* Lengthen the rod when the clearance is wider.
* Shorten the rod when the clearance is narrower.
3. Depress the clutch pedal, and check and make
certain that the free travel at the tip of the pedal
is 1.57 to 1.96 in. (40 to 50 mm)
1, With the clutch pedal depressed to the lowest
point, confirm that there is adequate gap
between the clutch rod and safety s t a r t e r
switch.
NOTE :
• Adjustment of the clutch pedal free travel
should be performed as explained above and
should not be judged by sight alone.
