Whenever the cover of the gearbox is removed, it is important to ensure that its gasket is properly
replaced to prohibit dust from entering. It is also important to reinstall all of the bolts in the cover, likewise
to ensure a dust-tight assembly.
6.3 DC Variable Speed Drive (1 and 2)
Lubrication should be in accordance with the manufacturer’s instructions as shown on the gear reduction
portion of the drive or in the instructions enclosed with this Manual (generally, a high grade SAE 140 gear
oil is recommended). Certain Gear-reducers (2) are permanently lubricated and are labeled as such.
Variable speed DC motors are equipped with two carbon brushes that should be first checked for wear
after about one year of operation. When approximately 3/8 to 1/2 of an inch of a brush remains, it should
be replaced to avoid potential damage to the motor’s armature and/or improper motor performance.
Brush life is dependent upon the duty and severity of operation for a given application. The DC motor is
furnished with permanently lubricated bearings. Refer to the separate instruction manual for information
relating to the specific SCR/DC controller.
6.4 AC Variable Speed Drive (1 and 2)
Lubrication should be in accordance with the manufacturer’s instructions as shown on the gear reduction
portion of the drive or in the instructions enclosed with this Manual (generally, a high grade SAE 140 gear
oil is recommended). Certain Gear-reducers (2) are permanently lubricated and are labeled as such.
Variable speed AC motors are virtually maintenance-free and include permanently lubricated bearings.
6.5 Seal Assembly (5)
The seals have been designed and constructed to eliminate any necessity for lubrication. Should any
material manage to penetrate the Synthetic Packing (17), it would be evidenced by a leakage deposit
beneath the Seal Housing Assembly (5), which is located between the rear wall of the Conditioning
Chamber (6) and Gearbox (3). Should material manage to penetrate the Synthetic Packing (16), it would
be evidenced by a leakage deposit within the Gearbox (3), as product not sealed by the packing
progresses through the hollow Intromitter (or Conditioning Auger) Drive Shaft (9) and into the Gearbox
(3), where the Intromitter (or Conditioning Auger) Drive Shaft (9) terminates.
Should product leakage be noticed on either the Metering Auger Drive Shaft (11) or the Intromitter (or
Conditioning Auger) Drive Shaft (9), the Packing (16 or 17) must be replaced. Both seals (and their
related packing) are spring-loaded to maintain constant pressure upon the packing material, with further
adjustment not possible.
6.6 Cleaning
Once power to the feeder has been disconnected,
the Model 105 Series of Volumetric Feeders may
be cleaned in a number of ways, depending upon how well this task must be performed.
After the feeder has been emptied of the product contained within (accomplished manually or by
permitting the feeder to run until empty), basic cleaning of a standard feeder can be achieved via a
vacuum device (without the need to remove any components). More thorough cleaning is possible by
removing the Intromitter (or conditioning auger), metering auger and discharge cylinder (as necessary
and as described within this Manual), thereby allowing better accessibility to internal areas.
These particular model feeders are also capable of a water wash-down (hot or cold) of all internal areas
using non-acidic detergents, if desired. Mild solvents, if approved by the factory, may also be utilized to
wipe-down internal areas of the feeder, typically to remove stains caused by certain type products.
