MAINTENANCE/SERVICE
WHEELS AND TIRES
Wheel Bolts
Check and tighten wheel bolts after the first 1 hour
operation and every 100 hours thereafter.
Whenever a wheel is removed and re-installed,
check torque after one hour of operation. Maintain
120 ft. lbs. (160 N.m) torque.
Follow proper bolt tightening sequence shown. Be
sure valve stem (A) points away from wheel
support.
CAUTION: When installing wheel be
sure to use the holes that are
countersunk to match bolt head
profile. The second set of "straight-
through" holes do not seat the bolts
correctly.
Wheel Removal - 12 & 14 ft. windrower
To remove either wheel on 12 foot windrower, or
left wheel on 14 foot windrower:
1. Raise header fully and engage lift cylinder
stops.
2. Jack side of unit to raise tire just off the ground.
3. Remove spindle retaining bolt (A) and slide
spindle outboard until clearance to vertical float
spring is adequate for wheel removal.
4. Remove wheel bolts and wheel.
5. When replacing wheel, torque nut on bolt (A) to
80 ft.lbs. (110 N ⋅m).
Tire Inflation
Check tire pressure daily. Maintain pressures recommended in Specifications section.
WARNING: Service tires safely. A tire can explode
during inflation and cause serious injury or death. Do
not stand over tire. Use a clip-on chuck and extension
hose. Never increase air pressure beyond 35 psi (241
kPa) to seat the bead on the rim. Replace the tire if it has a defect.
Replace a wheel rim, which has cracks, wear or severe rust.
Never weld a wheel rim. Make sure all the air is removed from a
tire before removing the tire from a rim. Never use force on an
inflated or partially inflated tire. Make sure the tire is correctly
seated before inflating to operating pressure.
Do not remove, install or make repairs to a tire on a rim unless
you have the proper equipment and experience to perform the
job. Take the tire and rim to a qualified tire repair shop. If the tire
is not in correct position on the rim, or is too full of air, the tire
bead can loosen on one side, causing air to leak at high speed
and with great force. An air leak of this nature can thrust the tire
in any direction, endangering anyone in the area.
