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 a 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
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 non-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 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.
Do not
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 allow anyone under the
motorhome without first properly
blocking frame (jackstands) from
coming down in case of rapid deflation
of air system.
Proper Drive Axle Lubricant Level:
With the motorhome parked on a level
surface and rear axle warm, place a
large container under axle.
Clean the area around the fill plug,
located approximately halfway up the
axle housing bowl.
