Center Link
The center link is located on the backside of
the steer axle. The center link attaches the two
wheels together causing the right front to track
with the left front. Greasing interval is every six
months or 5,000 miles.
Steering Spindles
The steering
spindles
attach to the
front axle and
pivot on the
kingpin. The
wheel end
assembly and
brake system
attach to the
spindle. There are upper and lower lubrication
points for the kingpin. The drag link attaches to
the roadside spindle. After initially lubricating
the roadside and curbside kingpins, rotate the
steering assembly lock to lock (full left to right)
then move assembly back to center. This purges
any remaining air pockets. Continue lubricating
the kingpins until new grease purges with no air
pockets. Greasing interval is every six months or
5,000 miles.
SteerIng gear
The steering gear has been designed to provide
long service life and simple service repair. The
rack and sector shaft does not require center
point adjustment. The clearance between the
cylinder bore and the piston is closely controlled
and a piston ring was added to better use the
hydraulic oil supplied. With reasonable care
and limited maintenance, the steering gear will
provide many miles of reliable performance. The
bleeder valve is used on intitial installation and
replacement.
Power steering is provided by using hydraulic
pressure to assist rotating the output shaft of
the steering gear. Located at the end of the
input shaft of the steering gear is a poppet valve
and worm drive. The poppet valve directs the
hydraulic uid pressure to a type of spool.
The worm drive threads into the center of the
spool. When in the center position, pressurized
hydraulic uid bypasses the spool. When a turn
is made, the poppet valve shifts to one direction
or the other, directing the hydraulic pressure
to one side of the spool depending on turning
direction. The hydraulic uid is then cooled
before returning to the reservoir.
NOTE:
Inspect for signs of leakage when
performing fluid level checks.
Changing the hydraulic lter in the engine
compartment at regular intervals will help
ensure trouble-free operation.
Front Disc Brakes
The components of the front brakes do not
require lubrication; therefore, there are no grease
zerks.
