Additive Feeders 

Chapter 5: Maintenance 

34 of 50 

This section provides you with the information necessary to correct or repair any issues 
which might appear during the normal operation of your additive feeder.  Although we have 
listed how to perform these procedures, it is recommended that you call the Service 
Department to have any in-depth maintenance performed. 

Auger Assembly Changeover 
Our additive feeder auger assemblies may be removed and installed without tools.  All auger 
sizes are interchangeable. 

1.  Empty the supply hopper by swinging open the cleanout hatch. 

2.  Disengage the motor assembly from the auger by removing the motor mount linchpin 

and swinging out the motor. 

3.  Pull the auger out. 

4.  Swing open the calibration hatch. 

5.  Release the UHMW auger insert by pulling out the spring loaded pluger and turning 

it a quarter turn. 

6.  Slide the auger insert out through the transport tube assembly. 

7.  Clean any remaining additive from inside the feeder. 

Make sure the insert and auger to be installed are a matching set. 

1.  Slide the UHMW insert into the material transport tube.  Line up the insert’s groove 

with the locking pin in the side of the transport tube.  Be sure the locking pin is 
retracted. 

2.  When the locking pin is aligned with the insert’s groove, release the locking pin.  The 

locking pin will ride in the groove as the insert is pushed into the transport tube. 

3.  When the insert is in place, the locking pin will snap into a retaining slot in the 

insert’s guide groove. 

4.  Insert the matching auger into the insert and line up the motor coupler with the pin on 

the end of the auger. 

5.  Fasten the motor assembly into place by restoring the linchpin to its original position. 

6.  Close and secure the calibration and cleanout hatches.
