To order other metering shafts, see“ Metering
Shafts (S/N C1009F- only) ” on page 104.
To install a set of these metering shafts, start with the
front meter.
1. Remove and save the pins (1) from the final
range gears (2) and (3).
2. Remove the spring clip (4).
3. Remove and save the final range gears. Note the
location for proper installation.
4. Carefully remove the current metering shaft (5).
5. Store the old metering shaft in the carton in
which the new metering shaft was supplied. Mark
the carton with the number of active hoses
(towers) and the number of stars. This will reduce
the risk of mistaking the carton/contents in the
future.
6. Carefully insert the new metering shaft (6) in the
meter box.
7. When the flange is fully seated against the box,
secure the flange with the six saved bolts. Give
the metering shaft a few turns.
8. Mount the final range gears. Note the pin hole
orientation on the shaft and on the gears. The
gears can only be pinned in 2 of the 6 possible
ways they can be placed on the shafts.
9. Install the pins.
For S/N
If your seeding rates need to be lower, select one of
the lower rate shafts.

Replacing the standard 4-star metering shaft with
a 2-star metering shaft decreases the seeding
rate by approximately 50% (to 50% of standard
rate).

For compatible seeds, replacing the standard
4-star metering shaft with the small seeds
metering shaft reduces the seeding rate by
approximately 90 to 75% (to a net of 10% to 25%
of standard rate).

For small seeds or other seeds substantially
smaller than 12 to 4.7 mm, the standard
metering shaft may not provide enough precision
and uniform flow at very low rates. The small
seeds metering shaft includes two half-width
shallow flute stars per compartment. For even
lower rates, plastic spacers can be used for one
small seeds star in each star assembly
(page 39).
All three types of metering shafts are standard.
To change metering shafts:
1. Remove the gear cover.
2. Remove and save the lynch pins (1) from the
final range gears (2) and (3).
3. Pull the retainer clip (4) to remove.
4. Remove and save the final range gears (2) and
(3), and the hub assembly (5).
Temporarily leave the gear on the metering
shaft to make a handle to pull the metering
shaft out of the meter.
5. Carefully remove the metering shaft.
6. Store the metering shaft in the tool box.
