AVERAGING SWITCH INSTALLATION
1. The averaging switch should be mounted in the boot housing of the clean grain
auger. so that grain being thrown hits and accumulates on the yellow face of the
switch.
See Diagrams 3 - 6. The switch must be horizontal and facing oncoming
grain. Allow clearance for both the auger and elevator, making sure that there will
be nothing on the sensor when the elevator empties. The point at which grain hits
the boot housing can be determined on used combines by finding where the paint
is worn.
2. Position the bracket to locate the mounting holes. See Diagram 3. Drill a 3/8”
diameter hole and a 1-1/8” diameter hole 2-3/4” apart. Attach bracket to the boot
housing with 5/16” x 3/4” bolt, lock washer and nut. If bracket is too long to fit in
housing, cut off excess length. Put switch through the larger hole and fasten with
two nuts supplied. Thread the averaging cup over the switch as shown in
Diagram 7 .
3. When mounting the bracket to the top of the boot housing, it must be bent so that
the switch is horizontal.
See Diagrams 4 - 6. Position the bracket to locate the
mounting holes and drill two 3/8” diameter holes two inches apart. Attach the
bracket to the top of the boot housing using two 5/16” x 3/4” bolts, lock washers
and nuts. Put the switch through the larger hole and fasten with the two nuts and
average cup supplied.
See Diagram 7.
