4.0 MAINTENANCE—DISASSEMBLY/REASSEMBLY
²
WARNING:
Be sure to disconnect the feeder from all power sources before
attempting to disassemble. Additionally, if a Drive Isolation (Mag-
netic) Clutch (81) — refer to Figure 4 — is provided to isolate the
Drive Motor (1) from the Gear-reducer (2), be certain that it has
been disengaged (via its local On/Off switch) before beginning dis-
assembly procedures.
IMPORTANT NOTE
The Numerical Component designations contained within this Instruction Manual (and the
following text) are strictly for reference purposes only and do not numerically coincide
with the Part Numbers indicated in the Feeder Parts List from which spare and/or replace-
ment parts should be ordered. Component names, however, are identical.
4.1 Metering Auger (10)
Please refer to Figure 2.
4.1.1
The Metering Auger (10), which contains a left-hand internally threaded hub, is fastened to its
Drive Shaft (11) within the Conditioning Chamber (6).
4.1.2
To remove the Metering Auger (10), rotate CLOCKWISE (when facing the discharge end of the
auger) until it is disengaged.
The Metering Auger (10) may be withdrawn through the Discharge Cylinder (12), or through the
front of the Conditioning Chamber (6).
To reassemble, reverse the preceding procedure.
CAUTION: Care must be taken when removing the Discharge Cylinder (12) if the Metering
Auger (10) has not been removed, particularly, on those feeders equipped with
an extended length metering auger, a solid flight type metering auger, or any
extended length metering auger furnished with an end bearing support. As
long as the Discharge Cylinder (12) is attached to the feeder, the Metering
Auger (10) is adequately supported, even if its end bearing support is loosened
or removed.
However, if the discharge cylinder is removed with the metering auger still
attached, a rigid type metering auger (solid flight type auger or any extended
length metering auger furnished with an end bearing support) can potentially
damage its drive shaft (bend the shaft) if the unsupported auger is allowed to
drop-down (due to its weight). Also, the Metering Auger Drive Shaft (11) can
likewise be damaged if such an auger was physically moved about in a manner
that could cause the threaded end of the drive shaft to bend (where it attaches
to the metering auger).
