a. Install the wave washer and flat washer onto the Crank Spindle. Note that the
wave washer sets against the crank.
b. Reinstall the Inner Pivot Block cover onto the Stairarm Pivot Block. Thread the
two 5/16" hex head bolts just enough to hold the cover in place. Do not fully
tighten the bolts which will not allow the stairarm to slide onto the Crank Spindle.
c. Then slide the Stairarm Pivot Block onto the Crank Spindle. Use the external
0.047" retaining ring pliers to reinstall the Stairarm Retaining Ring onto the Crank
Spindle.
d. Fully tighten the two 5/16" Inner Pivot Block cover hex head bolts.
e. Reinstall the Outer Pivot Block cover and secure using the #2 Phillips screw.
