Agitator Set Collar Adjustment
The following instructions describe how to properly adjust set collars on an agitator assembly
with a floating stir rod.
Step 1:
Make sure machine is OFF and
unplugged, then allow unit to cool completely
before attempting to adjust the agitator height.
Step 2:
Loosen the set screw in each set collar
to be adjusted.
Step 3:
With the kettle mounted in the popper,
adjust the shaft so the Agitator’s Spur Gear
contacts half of the Drive Motor Spur Gear
(reference Spur Gear Placement image at right).
DO NOT
set spur gears at full gear contact; it
can cause binding as the kettle is dumped.
Step 4:
Once shaft is positioned correctly,
re-tighten the set screw in the set collar above
the crossbar to secure in place.
Step 5:
Adjust clearance between the bottom of
the crossbar and the lower set collar to 1/32”
(thickness of a dime); then re-tighten set screw
to secure in place (see image below).
Step 6:
Adjust set collar for agitator weight to
be between 3/16” to 1/4” above the agitator
weight. Once adjusted, re-tighten set screw to
secure in place.
