attained.
Belt Maintenance
Servicing the Engine Belts
Service Interval: After the first 8 hours—Check the
condition and tension of all belts.
Every 200 hours—Check the condition and tension
of all belts.
Tensioning the Alternator/Fan Belt
1. Open the hood.
2. Check the tension by pressing the belt midway between
the alternator and crankshaft pulleys with 30 N-m (22
ft-lb) of force. A new belt should deflect 8 to 12 mm
(0.3 to 0.5 inch). A used belt should deflect 10 to 14
mm (0.4 to 0.55 inch). If the deflection is incorrect,
proceed to the next step. If correct, no further action
is required.

B. Using a bar, rotate the alternator until the proper
belt tension is attained, then tighten the mounting
bolts.
Replacing the Hydrostat Drive Belt
1. Insert a nut driver or small piece of tubing onto the
end of the belt tensioning spring.
WARNING
Use caution when de-tensioning the spring, as
it is under a heavy load.
2. Push down and forward on the spring end ( Figure 57 )
to unhook it from the bracket and release tension on
the spring.
