Major Components
Step Hardware
Composite plastic step with a rubber tread built into step top.
The step top and kick plate are held together and to the step chains by step hinges, threaded step shafts,
nylon spacers, bearings, washers, and bolts.
Drive System
The upper and lower sprockets are held to the
chassis of the machine by pillow block bearings
and connect the left-side and right-side step
chains.
Pillow blocks can be adjusted on the frame to
ensure alignment from upper to lower sprockets
and for tensioning the step chains.
As the steps rotate, bearings in the step shaft
hardware ride down the rails on bearing plates.
These bearing plates need to be greased with
white lithium, or marine grease.
