Changing Meter Flutes
To order high rate flute shafts, see “Alternate Flute
Sets” on page 106. To install a set of these shafts (or
re-install the standard shafts), start with the front meter,
as the task is a bit easier there. Save all parts for re-use.
Hopper must be empty for this procedure. see
“Unloading the Cart” on page 34.
Refer to Figure 92
1.
On the end of the meter box, remove and save the
lynch pins
from the meter box gears , and then
remove and save the gears.
Refer to Figure 93
2.
Remove and save the outer ring of six (6)
self-tapping hex head bolts
, that secure the outer
flange to the meter box.
Note: Do not remove the six bolts that secure the
bearing flangette to the outer flange. The shaft to
be installed includes its own flange.
Refer to Figure 94
(Shown with meter box off and various components removed
for clarity. It is not necessary to dismount or further
disassemble meters to swap flute shafts).
3.
From the right end of the meter box, carefully
withdraw the current flute shaft
. On older meters,
the flange has a bead of silicone as a gasket. You
may need to carefully pry the flange loose from the
box. Newer meters have a separate gasket.
4. Store the old shaft in the carton in which the new
shaft was supplied. Mark the carton with the number
of active hoses (towers) and the number of stars
(factory standard is 2). This will reduce the risk of
mistaking the carton/contents in the future.
5. For an older shaft without a separate gasket, apply a
bead of silicone sealant to the inside face of the
outer flange, just inside the bolt hole pattern.
6. Carefully insert the new shaft in the meter box.
7. When the flange on the right end is fully seated
against the box, secure it with the 6 saved bolts.
Give the shaft a few turns.
8. Re-mount the gears. Refer to the Seed Rate manual
for the gear assignments for the agitator and flute
shafts.
