WHEELS & TIRES
Examine wheels and tires periodically for correct
inflation pressures, tight wheel bolts, and any physical
damage that may be a detriment to Tractor operation
and operator safety. Correct condition prior to Tractor
operation.
Tire Inflation Pressures
FIG. 6-45: Maintaining correct tire pressure will help
insure tire long life. If tires have deep scratches, cuts
or punctures, the respective tire should be repaired or
replaced by qualified personnel as soon as possible.
IMPORTANT: If necessary to replace any tire(s),
ensure original tire size is used. This
is particularly true on 4-WD models
to ensure correct amount of front axle
overspeed (or lead) is maintained.
Wheel Bolt Torque
FIG. 6-46: Periodically check all wheel bolt torques.
Correct bolt torques:
Front Wheel Bolts, 1 .................... 155 ft.-lbs. (210 N
・
m)
Rear Wheel Nuts, 2 ..................... 275 ft.-lbs. (373 N
・
m)
Front Wheel Center to Rim Nuts, 3
..................................................... 155 ft.-lbs. (210 N
・
m)
Rear Wheel Center to Rim Nuts, 4
..................................................... 155 ft.-lbs. (210 N
・
m)
CAUTION: Correct wheel bolt torque must
be maintained. Installation of front or mid-
mounted implements (ex; loaders, mowers)
impose increased loads and require frequent
checking of wheel bolts.
Front Wheel Alignment
FIG. 6-47: Correct
t
oe-in dimensions of front wheels (A
minus B) are as follows:
4-WD ............................................0.08 to 0.24" (2-6 mm)
NOTE: Measure toe-in from tire center to tire center at
a point halfway up on face of each tire.
