Section 7 Maintenance
Proper maintenance can prevent unnecessary down
time and prolong the life of your planter.
Fasteners
When working on the planter torque all bolts, screws,
and nuts to the correct values listed in the Torque Val-
ues Chart in "Section 9 Specifications" on page 33.
Check latches and other fasteners on the planter to pre-
vent failures in the field.
Finger Pickup Meter
Inspect and repair the finger pickup meter by removing
the 2 bolts holding the meter to the hopper. Remove the
3 bolts on the meter baffle to gain access to the finger
mechanism.
Rotate the meter input shaft by hand to check the fin-
gers. The fingers should be against the carrier plate in
the area shown closed and raised in the area shown
open in Figure 7-1.
Inspect the brush for wear and replace every 100 acres
of row operation, see Figure 7-1 for location.
Chaf and debris can build-up in the meter preventing
proper functioning of the fingers.

To clean the corn meter:
1. Remove the cotter pin, lock nut, and adjusting nut
from the shaft.
2. Lift the finger assembly off the shaft and clean.
3. Replace worn fingers and springs by lifting the finger
out of the slot. Average life expectancy of these
parts should be 250-300 acres of row operation.
When fingers are replaced, the open end of the
spring loop should be toward the inside of the finger
housing.
4. Inspect the indentations in the carrier plate for wear.
Replace the carrier plate when wear to the plate be-
comes excessive or the seeding accuracy will be af-
fected.
5. Reassemble the meter in reverse order. Be sure the
fingers are installed correctly so the finger housing
is flush with the carrier plate. If the finger housing is
not flush with the carrier plate, make sure that the
projection on the cam is in the notch on the bearing
housing. The meter will not function properly if the
projection is not in the notch.
6. With the finger assembly against the plate, tighten
the adjusting nut until it is snug. Then turn an addi-
tional 1/3 turn. Turn the meter by hand making cer-
tain that the meter is not over tightened. Proper
meter resistance would be 22-25 in/lbs of torque ap-
plied at the meter input shaft.
7. Install the cage nut and the cotter pin.
8. Install the baffle and attach the meter to the hopper.
Check the belt on the meter periodically.
Use these steps:
1. Remove the 4 bolts located on the belt housing and
the bolt holding the belt roller.
2. Inspect or replace the seed belt.
3. Reassemble in the reverse order.
Note: Check tightness of the adjusting nut on the
meter after the first day and periodically thereafter.
