Belt Maintenance

Checking the Alternator Belt

Service Interval: After the first 10 hours
Every 100 hours
Check the condition and tension of the belt
every 100 operating hours.
1. Proper tension will allow 10 mm (3/8 inch) deflection
when a force of 44 N (10 lb) is applied on the belt
midway between the pulleys.
2. If the deflection is not 10 mm (3/8 inch), loosen the
alternator mounting bolts
decrease the alternator belt tension and tighten the
bolts. Check the deflection of the belt again to ensure
that the tension is correct.

Adjusting the Traction Drive
for Neutral
Note: If the machine has recently had the hydraulic oil
changed or the traction motors or hoses replaced, any air
trapped in the system will have to be worked out prior to
performing this procedure. This can be accomplished by
operating the machine in forward and reverse for a few
minutes and then replenishing the oil as required.
When positioned on a level surface, the machine must not
creep when the traction pedal is released. If it does creep,
adjust as follows:
1. Park the machine on a level surface, stop the engine,
and lower the cutting unit to the floor.
2. Jack up the rear of the machine until the rear tires are
off the shop floor. Support the machine with jack
stands to prevent it from falling accidentally.
Note: On 4 wheel drive models, the front tires must
also be off the shop floor and supported by jack stands.
WARNING
The engine must be running so this
adjustment can be performed. This could
cause personal injury.
Keep hands, feet, face, and other body parts
away from any hot parts of the engine and any
rotating parts.
3. Start the engine, set the throttle to the Slow position
and observe which direction the rear tires rotate.
Important: Make sure that the traction pedal is
in the neutral position.
•
If the left rear tire is rotating, loosen the jam nuts
on the left side transmission control rod
38).
Note: The forward end of the control rod has a
left hand thread. The rear end of the rod, which
is connected to the transmission, has a right hand
thread.
