CONSTRUCTION
Front suspension is the individual front wheel
type with independent support arms and coil
springs. This type of front wheel suspension per-
mits either wheel to absorb road irregularities
without effecting the other wheel.
Steering is from a center point which permits
smooth operation of the steering mechanism.
UPPER SUPPORT ARM
The upper support arm bushings (9) Figure 1,
fit into the upper support arm bores and are
threaded on to the ends of the pivot.
The assembly is attached to the frame side rails
at the No. 2 crossmember by two bolts (7). Shims
(10) between the upper support arm pivot and
frame member provide caster and camber adjust-
ments. At the outer end of the upper arm a
threaded pivot bolt (16) holds t h e spindle pivot
upper support (17) to the arm.
STEERING SPINDLE PIVOT PIN
The steering spindle pivot pin (46) i s threaded
into the upper support pivot. The outer steering
arm (53) is keyed to the steering spindle and the
pivot pin. Below the steering arm a t run n i o n is
mounted on the pivot pin. Steel threaded bushings
(19) fit into bores in the outer end of the lower arm
and onto the threaded portions of the lower sup-
port arm trunnion.
Wheel Bearing End Play .001" to .003"
LOWER SUPPORT ARM
Steel bushings (5) are inserted through bores in
the lower support arm at the inner e n d and onto
the threaded ends of the inner (23) pivot. Two bolts
(47) attach the pivot to the No. 2 crossmember.
The spring seat is riveted and welded to the
lower support arm. At the lower end the coil spring
(43) fits on the spring seat and the upper end into a
recess in the frame at the No. 2 crossmember.
Two rubber bumpers are used on the front
suspension, one on the upper arm (44) cushions and
restricts downward movement of the upper support
arm. The other on the lower support arm (51)
restricts upward movement of the assembly.
