EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES (Continued).
k.
Steering Pump and Reservoir.
The steering pump is a roller vane type pump with an
integral reservoir and fluid
filter.
The pump
is rated at 1.65 cubic inches per revolution.
The pump has an internal flow control and relief valve
protection system operating at 2,000 psi with flow 'rates up to 5 gallons per minute at 3,000 rpm shaft speed.
l.
Rear Tandem Axle Springs.
The rear tandem axle springs are a two-stage, leaf type.
When the vehicle has no
load, there is a gap between the
top leaf and the rear spring hanger so the weight of the vehicle is only on the top
leaves.
When the vehicle is loaded, contact is made with rear spring hanger so all leaves are used to carry the weight of
vehicle.
m.
Equalizer Beams.
The equalizer beams distribute load equally between the forward-rear and rear-rear axles.
This allows the vehicle to go over bumps and uneven roads and still have
equal weight on each axle.
There are
compressed sleeve bushings in the center and at each end of the beams.
n.
Front Axle Springs.
The
front
axle springs
are leaf
type.
They are attached to fixed pivot points in the front
and to shackles in the rear.
