Rear wheel tread adjustment
WARNING
Roll-over hazard!
Never operate the machine with a loose wheel
rim or disc. Always tighten nuts to the speci-
fied torque value and at the recommended in-
tervals.
Failure to comply could result in death or se-
rious injury.
Rear wheel track adjustment is affected by changing the
wheel rim relative to the center disc, the rim and/or the
disc relative to the axle hub or by interchanging the rear
wheels.
The sectioned drawings shown in the table illustrate the
wheel rim and disc positions viewed from rear of the trac-
tor relative to the hub at various track width settings. Track
width (the distance between the center of the tires) are
nominal and may vary by as much as 13 mm (0.5 in).
NOTICE: When interchanging left-hand and right-hand
wheel assemblies, ensure the "V" of the tire tread remains
pointing in the direction of forward travel of tractor for bet-
ter traction.
NOTICE: With certain options and/or tire sizes narrower
track settings may not be possible due to minimal clear-
ance between tires and fenders or equipment.
When installing or adjusting a wheel, tighten the bolts to
the following torques recheck after driving the tractor for 1
hour and 8 hours operation and thereafter at the 50 hour
intervals:
Rear disc to hub bolts
Rear disc to rim nuts
