Front Brakes
The slack adjuster and
camshaft need to be lubed
periodically to ensure
proper brake operation.
Lubricate every 10,000
miles or three months
using a NLGI #2 Lithium
soap-based lubricant.
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 pistion 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 poppet valve
and worm drive. The poppet valve directs the
hydraulic fluid pressure to a type of spool.
The worm drive threads in the center of the
spool. When in the center position, pressurized
hydraulic fluid 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 fluid is then cooled
before returning to the reservoir.
NOTE
Inspect for signs of leakage when
performing fluid level checks.
Changing the hydraulic filter in the engine
compartment at regular intervals will help
ensure trouble-free operation.
DrIve axle & DrIve SHaft
Drive Axle:
The chassis drive axle
is a single reduction
axle. The differential
gears consist of a
hypoid pinion and
ring gear set and bevel
differential gears. The
differential carrier can
be removed from the axle housing as a unit in
order to perform repairs.
All power from the engine to the rear tires is
transferred through the rear axle. For this reason,
it is important that maintenance be performed on
the axle as required to avoid premature wear of
the gears and bearings in the axle.
Drive Axle Lubricant:
The rear axle is filled with synthetic gear oil
meeting MIL-L-2105D specifications. Change
interval is every 250,000 miles or 36 months,
whichever occurs first.
During lubricant change, fine metal particles
will be observed clinging to the magnetic fill
and drain plugs of the axle. These particles are
normal wear particles from the axle components,
but will cause faster than normal wear of
the axle components if allowed to circulate
through the lubricant. It is recommended that
the magnetic plugs be tested, if not replaced, at
each lubricant change. These plugs should have
sufficient magnetic strength to pick up a 1.5
pound weight of low carbon steel. Never replace
a magnetic plug with a non-magnetic “pipe
plug” as they will not keep the lubricant clear of
metal particles or seal properly.
The level of lubricant in the rear axle should
be checked every 30,000 miles or 6 months,
whichever occurs first. This will ensure adequate
lubricant in the axle for proper operation.
Regular inspection of the drive axle lube levels
is an essential maintenance procedure.
WARNING
Do not place yourself under motorhome
without first properly blocking frame
(jackstands) from coming down in case
of rapid deflation of air system.
Typical Air Drum Brakes:
Lubricate until new grease
appears at exit points.
