Row-Unit Side Wheels
Figure 72
1.
Lift opener side wheel off the ground. Move tire in
and out to check for end play. Check for roughness in
bearing by rotating wheel. If bearings are rough,
inspect and replace if necessary.
2. The side wheels are preset at the factory. However,
because of normal wear it may become necessary to
make adjustments so the wheel remains close to the
disk. To prevent plugging, loosen clamp bolt
➆
and
slide arm inward to take up gap between side wheel
and disk blade. If more adjustment is needed, go to
step 3.
3. Remove bolt
➉
and wheel
➁
. Remove shims
➀
from
the inside of wheel
➁
and place them on the outside
of wheel. Always place removed shims from the
inside to the outside. When installed, wheel should
turn freely and not hit the arm at the curve. Do not
add any more shims than necessary.
4. Disassemble side gauge wheel arm
➂
from unit.
Remove bushing
➃
from sleeve
➄
and check for
wear. If necessary, replace bushing.
5. When reinstalling side gauge wheels, align tab on
hex adjustment

with notch in bushing. Replace
bolt and tighten.
6. Adjust side gauge wheels. See “Side Gauge Wheel
Adjustments” on page 45.
