Inspecting Meter Fingers
Inspect the brush for wear. The brush should cover at least
half of a finger tab. Replace brush after every 100 acres of
planter operation.
Clean chaff and debris from meter after every 50 hours of
planter operation. To clean meter, see Figure 5-3.
1. Remove cotter pin (1), cage nut (2) and adjusting nut
(3) from shaft.
2. Lift finger assembly (4) off shaft and clean. Replace
worn fingers and springs after 250 to 300 acres of row
operation. To remove a finger, lift finger out of slot.
When replacing a finger, place the springs so the open
side of the spring loop faces the inside of the spring
housing.
3. Inspect carrier plate (5) for seed indentations and
wear. Replace carrier plate when wear affects seeding
accuracy.

4. Reassemble finger housing onto carrier plate. When
reassembling, align notch in finger-housing cam (1)
with notch on bearing housing so finger housing is
flush with the carrier plate. The meter will function im-
properly if the notches are not aligned.

odically thereafter.
