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
1. Raise header fully and engage lift
cylinder stops.
2. Position 5000 lb. capacity jack on mount
provided on frame leg and raise tire just
off the ground. Place block under frame
leg at (A).
3. Remove wheel bolts
4. NOTE: To remove either wheel on 12
foot windrower, or left wheel on 14 and
16 foot windrower – Remove spindle
retaining bolt (B) and slide spindle
outboard until clearance to vertical float
spring and chain drive housing is
adequate for wheel removal.
5. Remove wheel.
6. When replacing spindle retaining bolt
(B), torque nut 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.
