NOTE:
The Conditioning Chamber (6) with the Seal Housing Assembly (5) and Gearbox (3),
including the Variable Speed Drive (1 and 2), may be removed as an assembly from the
Feeder Mounting Base (4), if so desired.
To reassemble, reverse the preceding procedure.
4.5 Seal Housing and Gearbox Assembly—Type PB (5 and 3)
Please refer to Figures 2 and 4.
4.5.1
The Seal Housing (5) and Gearbox (3) may be separated from the Conditioning Chamber (6) as
an assembly by removing the bolts that fasten the Seal Housing (5) to the rear plate of the
Conditioning Chamber (6).
NOTE 1:
It will be necessary to first remove the Metering Auger (10) and the Intromitter or
Conditioning Auger (8) before the Conditioning Chamber (6) can be separated from the
Seal Housing (5) and Gearbox (3) assembly.
NOTE 2:
The Model 105 Series of Volumetric Feeders include machined gearbox assemblies
which include specially designed (piloted) two bolt flange bearings with Type PB
Gearboxes. In order to maintain the accuracy of this assembly, replacement bearings
must be identical to the original, and therefore, the Serial Number of the feeder must
always be given should replacement parts for the Gearbox (3) be ordered.
NOTE 3:
Feeders furnished with a Torque Limiting Coupling (80) require removal of the torque
limiting coupling before disassembly of the Gearbox (3), as outlined in the preceding, is
possible. The torque limiting coupling is located between the Gearbox (3) and the
attachment flange of Gear-reducer (2) that attaches the gear-reducer to the Gearbox
(3).
4.5.2 Replacing Gears
can be accomplished without removing the Gearbox (3) from the feeder
assembly (see Figure 2). First, remove the Metering Auger (10) and the Intromitter or Conditioning
Auger (8). Then, remove the Drive Assembly (1 and 2) by loosening the two set screws on the
hollow-shaft of the Gear-reducer (2)—when applicable—and removing the four mounting bolts
which secure the Gear-reducer (2) onto the Gearbox (3). If the Gearbox (3) must be removed,
remove the bolts fastening the Seal Housing Assembly (5) to the Conditioning Chamber (6) and
the single bolt fastening the Gearbox (3) to the Feeder Base (4).
4.5.3 To remove Gear (22),
loosen the two set screws on this gear and the two set screws on the
adjacent Metering Auger Drive Shaft Bearing (37). Loosen the Metering Auger Drive Shaft Seal
Cap (14) and then, pull the Metering Auger Drive Shaft (11) out through the back of the Gearbox
(3), or alternately, into the Conditioning Chamber (6) as far as necessary to permit removal of the
gear (see the two NOTES following paragraph 4.5.6). Only after this has been done can Gear
(25) also be removed.
4.5.4 To remove Gears (23) and/or Gear (24),
loosen the two set screws on each adjacent
Countershaft Bearing (31) and the two set screws on each of the gears. Slip Countershaft (28) out
through the back of the Gearbox (3) far enough to remove the gear or gears.
4.5.5 To remove Gear (25),
follow the procedure outlined in the preceding paragraph 4.5.3 for
removing Gear (22). Then, loosen the two set screws on Gear (25) and on the adjacent
Conditioning Auger Drive Shaft Bearings (38). Unthread the Conditioning Auger Drive Shaft Seal
Cap (15) and then, pull the Intromitter (or Conditioning Auger) Drive Shaft (9) into the Conditioning
Chamber (6) far enough to allow removal of Gear (25).
