Attach the treadle yoke to the
treadle (Figure 9). Thread the 1-1/2"
yoke screw through the metal washer
and split lock washer, then through
the bottom of the treadle. Screw the
yoke screw into the treadle yoke
with a Phillips screwdriver. Leave
approximately 1/4” of the yoke screw
exposed between the top of the treadle
and the bottom of the treadle yoke. You
can adjust the treadle’s position later if
necessary; see “Adjusting the Treadle
Height.” Repeat for the other treadle
and treadle yoke.
20.
Attach the footmen to the treadle
yoke using the cotter pin, clevis pin,
and small nylon yoke washers (Figure
9). The shorter treadle is attached to
the footman that is closest to the back
of the wheel. Place the footman leather
inside the treadle yoke and line up the
holes. Put a small nylon washer on
a clevis pin and insert the clevis pin
from the back of the wheel towards
the front. Put another small nylon
washer on the clevis pin and secure
by inserting a cotter pin through the
clevis pin until the cotter pin is about
halfway through the clevis pin.
The longer treadle is attached in
the same way, but the clevis pin should
be inserted through the footman and
treadle yoke from the front of the
wheel toward the back.
ADJUSTING THE TREADLE HEIGHT
This adjustment is only necessary if
your treadle is either rubbing the drive
wheel or hitting the rear leg cross
support. To adjust the treadle height,
remove the cotter pin from the clevis
pin and pull it from the treadle yoke.
