adjustment and wear. Replace outside
scrapers as necessary.
Opener Side Wheels
Refer to Figure 78
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 the bearings are rough, inspect and re-
place 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 (7) and
slide arm inward to take up gap between
side wheel and disk blade. If more adjust-
ment is needed go to step 3.
3. Remove bolt (10) and wheel (2). Remove
shims (1) from the inside of the wheel (2)
and place them on the outside of the
wheel. Always place the shims removed
from the inside to the outside. When in-
stalled, the 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 (3)
from unit. Remove bushing (4) from sleeve (5)
and check bushing for wear. Replace bushing if
necessary.
5. When reinstalling side gauge wheels, align tab
on hex adjustment (6) with notch in bushing.
Replace bolt and tighten.
6. Adjust side gauge wheels. Refer to “Adjust-
ments,” page 24.

CAUTION
Disk edges are sharp. Be careful when working in this
area.

Disk Spreaders and Scrapers
NOTE: It is normal for the blade spreader to
have some looseness in the holder and be-
tween the blades. Some looseness is required
for proper operation.
Refer to Figure 77
1.
Remove side gauge wheels from arms to
access opener disks and scrapers.
2. With unit raised, check blade spreader (1)
for wear. Replace spreader if it is 1/2 inches
wide or narrower. To replace, remove disk
blade (3). Drive out roll pins (2) and install
new spreader.
3. When reinstalling disk blades, put two
shims (4) between bearing and shank on
each blade. Tighten bolts.
NOTE: You may need fewer washers on
worn disks.
4. Check that outside disk scrapers (5) are
formed to disk blades to help remove any
mud. Bend and twist scrapers to fit blades
as necessary. After every 200 acres of op-
eration, check outside scrapers for proper
