Check for roughness in the bearing by rotating
the wheel. If the bearings are rough, inspect and
replace, if necessary.
2. The side gauge wheels are preset at the factory.
With normal wear, it may become necessary to
make adjustments so the wheel remains close to
the disk.
Loose the clamp bolt (4) and slide the gauge
wheel arm (5) in to take up the gap between the
side wheel and disk blade.
If more adjustment is needed:
a. Remove the bolt (6) and wheel (7).
b. Remove the shims (8) from the inside of the
wheel and place them on the outside of the
wheel (9).
Always place removed shims from the inside to
the outside. When installed, the wheel should
turn freely and not hit the arm at the curve. Do
not add any more shims than necessary.
c. Disassemble the side gauge wheel arm (5) from
the row unit.
d. Remove the bushing (10) from the sleeve (11)
and check for wear. If necessary, replace the
bushing.
e. When reinstalling the side gauge wheels, align
the tab on the hex adjustment (12) with the notch
in the bushing.
f. Install the bolt and tighten.
g. Adjust the side gauge wheels. See “ Disk-to-
Disk Spacing ” on page 40.

Disk Spreaders and Scrapers
Maintenance
Sharp Objects Hazard
Disks are sharp and may result in injury.
Wear hand protection when working in this
area.
1. Remove the side gauge wheels from the arms to
access row unit disks and scrapers.
2. With the unit raised, check the blade spreader (1)
for wear. Replace spreader if it is 1/2 inch (13
mm) wide or narrower. To replace:
a. Remove the disk blade (2).
b. Drive out all pins (2).
c. Install new spreader.
For proper operation, the scraper separator
must be a little loose in the holder and
between the blades.
3. When reinstalling disk blades, put two shim
washers (4) between the bearing and shank on
each blade. Tighten the bolts.
You may need fewer inside shim washers
on worn disks.
4. Check that outside disk scrapers (5) are formed
to the disk blades to help remove any mud. Bend
or twist the scrapers to fit the blades as
necessary.
After every 200 acres (80 ha) of operation, check
outside scrapers for proper adjustment and wear.
Replace the outside scrapers, as necessary.

Marker Maintenance
The marker arm is attached to the marker body with
a 7/16 x 2 inch Grade 5 shear bolt. If the shear bolt
breaks, replace shear bolt (part number 802-589C)
or with an equivalent.
If an identical Grade 5 bolt is not immediately
available, temporarily substitute a metric M12 x 1.5 x
6.4 mm Class 8.8 bolt and nut.
Equipment Damage Risk:
Replacing the shear bolt with a higher grade
of bolt can result in marker damage.
Do not replace the shear bolt with a lower
grade bolt, or a smaller bolt, or may
experience nuisance shears.
If conditions are causing frequent shears, keep spare
bolts in the storage holes of the marker shear base.
