LIFTING FROM UNDER THE FRONT AXLE
2.
Operate the engine when towing to
maintain brake system air pressure. If the
engine cannot be operated, connect an
external air pressure line from the tow truck
to the emergency fill valve in the engine R.H.
side compartment. The emergency fill valve
in the front service compartment does not
supply air pressure to the brake system. The
air pressure must be a minimum of 75 psi
(520 kPa), and the line should be attached to
the air line with a clip-on chuck.
CAUTION
Do not tow the vehicle without external air
pressure applied to the emergency fill valve
if the engine does not operate. Without
brake system air pressure, the brakes may
apply automatically if system air drops
below 40 psi (275 kPa). If failure prevents
releasing the parking brakes with air
pressure, disengage the parking brakes
mechanically.
3.
Observe safety precautions when towing.
CAUTION
Make sure a safe distance is kept between
the front of the coach and the tow truck.
This space ensures that coach does not
suffer damages when being towed.
CAUTION
Make sure axle shafts or driveshaft are
installed correctly after towing. Tighten
axle shaft and driveshaft nuts to the
correct torque settings. Do not invert
shafts.
TOWING WITHOUT LIFTING
CAUTION
When towing vehicle without lifting, use
only a tow truck with a solid link tow bar
and related equipment. All other means of
towing are unauthorized. Tow only from the
front of the vehicle.
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.
Operate the engine when towing to
maintain brake system air pressure. If the
engine cannot be operated, connect an
external air pressure line from the tow truck
