Section 4: Motor to Drum Assembly
Using the larger hex key
(allen wrench) loosen the
set screw located on the
chrome center piece of the
black pulley until it is no
longer poking out the
bottom of the pulley
Now slide the large black
pulley on the right side axle
with the notched slot
pointed outward.

The small roll pin will need
to be hammered in the hole
drilled through the axle at
the edge of the threaded part
of the axle.

Center the roll pin in the
axle with the same amount
sticking out each end. Slide
the pulley outward. The roll
pin needs to fit in the slot on
the pulley. (photo 4-2b)
When the roll pin is firmly
set in the slot, use the hex
key to tighten the set screw
snugly. Do not over tighten.
This keeps the pulley from
sliding away from the roll
pin. (photo 4-2c)
Now screw the nut cap on
the end of the axle and
using the 3/4” wrench,
tighten snugly.

The belt is next. Place it
around the motor and drum
pulleys (photo 4-4a)
Slide the tension wheel
toward rear until the belt is
taut and tighten with screw
driver and 1/2” wrench.
