ROADWHEELS AND SUSPENSION. Twelve roadwheels, dual-mounted on six hubs, carry
vehicle weight on upper surface of lower track span.
Space between dual-mounted
wheels is running
channel for track alining centerguides.
Roadwheel arms 1, 2,
and 6 bear shock absorber mounts. Each arm is sprung with torsion bars.
COMPENSATING IDLER WHEELS.
Identical to and interchangeable with roadwheels,
serves as track alining channel for centerguides
and maintains track tension by
means of track adjusting link connected to roadwheel number one
and idler arm
which forces idler wheel forward or rearward to maintain
constant tension on
unloaded free portion of track.
TRACK SUPPORT ROLLERS. Five dual-mounted track support rollers on each side of
vehicle support upper track span between sprockets
on drive hub and compensating
idler wheels. One track support roller also drives the speedometer.
