Servicing the Engine Belts

Tensioning the Alternator/Fan Belt
1. Prepare the machine for maintenance.
2. Unlatch and open the hood.
3. Check the alternator/fan belt
pressing the belt midway between the
alternator and crankshaft pulleys.
Note:
should deflect 11 mm (7/16 inch).
4. If the deflection is incorrect, complete the
following procedure to tension the belt:
A. Loosen the bolt securing the brace to the
engine and the bolt securing the alternator
to the brace.
B. Insert a pry bar between the alternator and engine and pry the alternator outward.
C. When you achieve proper belt tension, tighten the alternator and brace bolts to
secure the adjustment.
5. Close and latch the hood.
Replacing the Hydrostat Drive Belt
1. Insert a nut driver or small piece of tubing onto the end of the belt tensioning spring.
When you replace the hydrostat drive belt, you must release the tension on the
spring, which is under a heavy load. Releasing the tension on the spring improperly
could result in death or serious injury.
Be careful when releasing the tension on the spring.
2. Push down the end of the belt-tension spring down and out of the notch in the tab of the
pump mount, and move the spring end forward.
