Procedure 7.6 - Replacing a Crankarm Assembly

Warning: Care must be taken when work is being performed in the area of the stairarms. Pinch
points exist between the stairarm and ramp and between the stairarm and crankarm,
when the rear covers are removed.
Procedure
1. Set the on/off switch in the "off" position, then unplug the power cord from the A.C. outlet.
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in
Section One, Things You Should Know.
2. Remove the left and/or right cover section as described in Procedure 7.1.
3. Remove the left and/or right stairarm assembly as described in Procedure 7.17.
Note:
Notice the position of the two crank arms. When the crankarms are replaced, they must be
positioned so that they are 180 degrees opposing.
4. Remove the bolt that secures the crankarm to the input pulley shaft. It will be necessary, use
a Pitman arm puller or 4" to 6 "gear puller to remove the crankarm. Do not use a hammer or
mallet to remove the crankarm.
5. If you are removing both crank arm assemblies, repeat Steps 3 and 4 for the second
crankarm assembly.
