Replacing the Traveling V-belt

1. Check the traveling V-belt for damage by

viewing it from the rear of the machine.

2. If the V-belt is damaged, remove the HST fan

cover and take out the belt stopper on the engine
pulley side.

3. Open the engine cover and remove the
cutting-blade belt cover. (Refer to p. 64 of this

manual.)

4. Loosen the adjusting nut to loosen the traveling

tension spring, which is tensioning the traveling
V-belt. (Refer to p. 64 of this manual.)

5. Remove the cutting-blade V-belt, and then
remove the traveling V-belt by lifting it up from

the transmission pulley groove.

6. Install a new traveling V-belt and then install

the cutting-blade V-belt.

7. Adjust the tension of the traveling V-belt. (Refer

to p. 64 of this manual.)

8. Adjust the position of the belt stopper until

the gap between the belt stopper on the engine
pulley side and the engine pulley becomes 2 to 3
mm.

Check the traveling V-belt for damage. If the belt has cracks or worn, replace it
with a new part according to the procedure below.
