Drive System
Maintenance
Checking the Tire Air
Pressure
Service Interval:
Before each use or daily
Important:
Maintain the recommended pressure
in all tires to ensure a good quality of cut and
proper machine performance. Do not underinflate
the tires.
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 41)
.
2.
Measure the tire air pressure.
Note:
The correct air pressure in the tires is 83
to 103 kPa (12 to 15 psi).
3.
If needed add air to or remove air from the tire.
4.
Repeat steps
and
at the other tires.
Checking the Torque of the
Wheel Nuts
Service Interval:
After the first 8 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel
nuts could result in failure or loss of a wheel
and may result in personal injury.
Torque the front and rear wheel nuts to
115 to 136 N∙m (85 to 100 ft-lb) after 1 to 4
hours of operation and again after 8 hours of
operation. Torque the wheel nuts every 200
hours thereafter.
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 41)
.
2.
Torque the wheel nuts to 115 to 136 N∙m (85 to
100 ft-lb).
Note:
The front wheel nuts are 1/2–20 UNF;
the rear wheel nuts are M12 x 1.6-6H (metric).
Checking for End-Play in
the Planetary Drives
Service Interval:
Every 400 hours
DANGER
A machine on a jack may be unstable and slip
off the jack, injuring anyone beneath it.
•
Do not start the engine while the machine
is on a jack.
•
Always remove the key from the switch
before getting off the machine.
•
Block the tires when you are raising the
machine with a jack.
•
Support the machine with jack stands.
There should be no end-play in the planetary
drives/drive wheels (i.e., the wheels should not move
when you pull or push them in a direction parallel to
the axle).
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 41)
.
2.
Chock the rear wheels and raise the front of
machine; refer to
Specifications (page 25)
and
Locating the Jacking Points (page 43)
.
3.
Support the front frame of the machine with jack
stands.
4.
Grasp 1 of the front drive wheels and push/pull it
toward and away from the machine, noting any
movement.
