Inspect the brush for wear. The brush should cover at least
1/2 of the finger pickup tab. Replace every 100 acres of
row operation. See for location.
Chaff and debris can build-up in the meter preventing
proper functioning of the fingers. Clean every 50 hours of
operation.
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 fin-
gers 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 projec-
tion 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 additional
one-third turn. Turn the meter by hand making certain
that the meter is not over tightened. Proper meter re-
sistance would be 22 to 25 inch-pounds 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.
IMPORTANT: Check tightness of the adjusting nut
on the meter after the first day and periodically there-
after.
Check the belt on the meter periodically. Use these steps:
1. Remove the four bolts (1) located on the belt housing,
the bolt holding the belt roller and the belt housing
cover (2). See Figure 5-8.

NOTE: See Figure 5-9 if belt is replaced. Be certain pad-
dles (A) are oriented as shown. Belt drive wheel (B) may
be removed by removing spring pins (C).
