2. The issue may be caused by a crooked weld on the crank arm pin
(AJ1). If the problem has not been resolved by removing the lower
connecting arm. To rectify this issue it may be possible to reposition
the spacing of washers J08 (qty 2) and washer E13. To determine the
correct spacing, first identify on which side of the guide rail the pedal
arm wheels are jumping off of the guide rail. For example, if the
pedal arm wheels are jumping off of the inside of the guide rail, in
theory the pedal arm needs to be placed further away from the
machine and if the pedal arm wheels are jumping off of the outside of
the guide rail, in theory the pedal arm needs to be placed closer to the
machine. Once this has been determined, remove c-clip J09 with a
snap-ring pliers and reposition the washers as necessary. It may be
necessary to try a few different configurations of the washer spacing.
