Finger Set Installation Instructions
Installation Steps
Great Plains recommends having the meter service per-
formed by a recognized professional repair facility, such
as a certified Meter Max representative. Improper servic-
ing will result in reduced meter performance.
If you choose to service them yourself, follow these pro-
cedures when installing the finger sets.
Refer to Figure 87
1. Be sure the belt is oriented as shown in Figure 87.
2. Slide the finger set over the shaft and rotate clock-
wise until it sits against the backing plate.
Note: You will hear a click.
3. Firmly press the finger set against the backing plate
while tightening the nut.
4. Tighten the nut until contact is made between the nut
and the finger set. Turn

flat ( 1 ⁄
24
to 1 ⁄

of a
turn) (a flat is one of the six sides of the nut) after
contact is made. This equals about four inch- pounds
of torque on the nut.
5. Place the slotted nut cover on and carefully align the
slotted nut cover with the shaft hole. Insert the cotter
pin.
6. Rotate the finger set clockwise and make sure the
fingers open and close properly. Fingers should be
closed at the 8:00 to 2:00 position (exit hole) and
open at the 2:00 to 8:00 position.
Annual Maintenance
Finger sets should be inspected on an annual basis.
After cleaning, carefully inspect the fingers and springs
for wear or other abnormalities that may develop. Exces-
sive wear may disrupt singulation performance.
Precautions
1.
Make sure the finger set is properly torqued against
the backing plate. Improperly torqued finger sets
may disrupt seed singulation.
2. Avoid seed treatments, additives, and other chemi-
cals when possible. They can cause meter perfor-
mance problems, premature wear to meter parts,
and may cause undesired chemical reaction or dete-
rioration to the finger sets. Always use Precision
Planting or Great Plains graphite when using seed
treatments, see “Seed Lubricants” on page 19.
Graphite from other sources may cause premature
wear.
3. Always pay attention to your seed monitor, pay atten-
tion to your operating manual, and monitor the
amount of seed you are planting compared to your
expectations. Always investigate abnormalities!
