Finger Set Installation instructions
Installation Steps
Great Plains recommends having the meter service
performed by a recognized professional repair facility,
such as a certified meter Max represenative.
If you choose to service them yourself follow these
procedures when installing the finger-sets.
1.
Be sure the belt is oriented properly as shown.
2.
Slide the finger set over the shaft and rotate
clockwise until it properly seats against the backing
plate (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 1/4 to 1/2 (1/24 to 1/12 of a
turn) flat (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 and 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.
Excessive 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
chemicals when possible. They can cause meter
performance problems, premature wear to meter
parts and may cause un-desired chemical reaction
or deterioration to the finger sets. Always use
Precision Planting or Great Plains graphite when
using seed treatments, refer to "Graphite Powder,"
on page 20. Graphite from other sources may cause
premature wear.
3.
Always pay attention to your seed monitor, operating
manual and monitor the amount of seed you are
planting compared to your expectations. Always
investigate abnormalities.
