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.

Replace the standard 4 - star metering shaft with a
2 - star metering shaft to decrease the seeding
rate by approximately 50% (to 50% of standard
rate).

For compatible seeds, replace the standard
4 - star metering shaft with the small seeds
metering shaft to reduce the seeding rate by
approximately 90 to 75% (to a net of 10% to 25%
of standard rate).

For small seeds or other seeds smaller than 12 to
4.7 mm, the standard metering shaft may not
provide enough precision and uniform flow at
very low rates. For lower rates, plastic spacers
can be used for one small seeds star in each star
assembly (page 46).
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).
