WARNING
Always unload or retract the tag axle before
jacking the vehicle from the front and drive
axle jacking points to prevent damage to
suspension components.
JACKING POINTS ON TAG AXLE
11029
WARNING
The jacking points on the tag axle must be
used for raising the tag axle only.
Several kinds of hydraulic jacks can be used.
Only jack at the specified jacking points. Jack
must support the following capacities:
Front axle: 20,000 lb (9 100 kg);
Drive axle: 40,000 lb (18 200 kg).
HYDRAULIC JACK
To raise: turn release valve clockwise. Insert
handle in socket and raise by pumping.
To lower: remove handle and turn the release
valve slowly counterclockwise.
Always keep ram and extension screw retracted
when jack is not in use.
Service: Check oil level when jack fails to raise
to full height. Lower ram completely with release
valve open and jack in upright position, remove
filler plug and refill to level of filler hole with
hydraulic jack oil.
Never use brake fluid.
DANGER
Jack is intended for lifting only. Do not get
under the vehicle or load for any reason
unless it is properly supported with safety
stands and securely blocked.
DANGER
Do not load jack above rated capacity. Prevent
"side loading", make sure load is centered on
ram. Do not push or tilt load off jack.
LIFTING AND TOWING
The towed vehicle must be lifted from the front
end only. The tow truck must be equipped with
the proper lifting equipment to reach under the
front axle or the front tow eyes since no other
lifting points are recommended. Lifting and
towing from any other point are unauthorized as
it may cause serious damage to the structure.
Do not unload or raise the tag axle when lifting
and towing to prevent overloading the drive axle.
1. Remove both drive axle shafts to prevent
damage to the transmission. Plug axle tube
to prevent oil loss. Refer to Rockwell's
"Maintenance manual no.5" annexed at the
end of Section 11: Rear Axle of the
maintenance manual.
CAUTION
Transmission lubrication is inadequate when
towing. With automatic, semi-automatic or
manual transmission, the axle shafts or
driveshaft must be disconnected to avoid
serious damage to the transmission. Do not
attempt to push or pull-start the coach.
2. If required, raise the front of the coach then
install wooden blocks underneath front tires
to allow lifting equipment to reach under the
front axle.
