6. INSTALLING THE CRANK-AND-FOOTMEN [Parts bag #6]
1.
Slide the long end of the crank from the crank-and-footmen assembly into the open end of the drive
wheel axle, lining up the hole in the axle with the threaded hole in the crank arm.
2.
Secure the crank to the axle using the 8-32 x 5/8" crank-to-axle bolt. Tighten the bolt using the 9/64"
hex wrench until the crank does not wriggle in the axle.

3.
Secure the treadles to the footmen. Slide the #10 x 1.25 treadle-to-footmen screws up through the
holes in the treadle arms and into the rubber connectors at the bottom of the footmen. The outer
footman connects to the longer treadle, the inner footman to the shorter treadle. Tighten until snug,
but do not over-tighten. This step is made easier if you tilt the assembly back on the drive wheel as
suggested in Step 2.11. After the screws are installed, twist the footmen so that the sides of the wooden
uprights, and the straps holding them to the crank, are all parallel to each other and to the drive wheel
as well. The treadle-to-footman screw may have to be loosened a bit to assist in twisting to parallel.
