First, install the Metering Auger Drive Shaft (11) if it was removed (please refer to paragraph
4.7.1). Then, install Spring (18) and carefully replace the packing, one ring at a time. Make sure
the packing is clean and has not picked-up any dirt in handling. Seat the individual rings of
packing firmly, making certain that the joints of successive rings are staggered and kept at least
90 degrees apart (see Figure 4 for reference and NOTE 1 following paragraph 4.6.2). After the
Packing (16) has been replaced, install Seal Cap (14).
Replacing Packing (17)
4.7.7
Remove both the Intromitter (or Conditioning Auger) (8) and the Metering Auger (10). Then,
loosen and remove the two nuts that secure the Seal Cap Pressure Plate (91). Slide the Seal Cap
Pressure Plate (91) and Seal Cap (92) backward to gain access to the Packing (17). Once
completed, remove the Packing (17) with a small screwdriver or needle-nose pliers. Examine the
Intromitter (or Conditioning Auger) Drive Shaft (9) for wear and/or scoring; replace if worn or
scored.
NOTE:
In order to best examine the Intromitter (or Conditioning Auger) Drive Shaft (9), the
shaft may need to be moved forward. To accomplish this, please follow the procedure
outlined in paragraph 4.7.2.
4.7.8 To reassemble, reverse the preceding procedure.
First, install the Intromitter (or Conditioning Auger) Drive Shaft (9) if it was removed (please refer
to paragraph 4.7.2). Then, carefully replace the packing, one ring at a time. Make sure the
packing is clean and has not picked-up any dirt in handling. Seat the individual rings of Packing
(17) firmly, making certain that the joints of successive rings are staggered and kept at least 90
degrees apart (see Figure 4 for reference and NOTE 1 following paragraph 4.6.2). After the
Packing (17) has been replaced, install the Seal Cap (92) and Seal Cap Pressure Plate (91) and
tighten until a small amount of pressure is exerted upon the packing.
NOTE:
This adjustment should again be made after the first several hours of operation to
ensure that a proper seal exists. Adjust as required.
4.8 Drive Motor and Gear-reducer (1 and 2)
Please refer to Figures 2 and 5.
4.8.1
Standard Models 105, 105X and 105Z Feeders are furnished with a hollow-shaft Gear-reducer (2)
drive which is directly flange-attached to the Gearbox (3). The entire Gearbox (3) assembly,
including where the Gear-reducer (2) attaches, is machined for a totally precision package. The
Gear-reducer (2) is secured to the Gearbox (3) with four bolts, and is furnished with a “C” flange
for direct attachment of the Motor (1).
When a Torque Limiter Coupling (80) is furnished, the Gear-reducer (2) is spaced-off the Gearbox
(3) to both allocate the additional area required to accommodate the Torque Limiter Coupling (80)
and also, to provide access for adjustment of the torque limiter coupling. In such instances, the
Metering Auger Drive Shaft (11) is split where the Torque Limiter Coupling (80) is installed. To
obtain full access to the Torque Limiter Coupling (80), the Gear-reducer (2) must be removed.
Instructions relating to the torque limiter coupling are furnished separately with this Manual.
4.9 Tachometer Assemblies (DC Drives)
