VEHICLE RECOVERY AND SPRING
BRAKES
Introduction
Your Model 330 is equipped with built-in recovery provisions,
designed for short distance use only. If your vehicle must be
recovered, disconnect the driveline at the rear U–joint, and
remove or support the rearmost section of the driveline. This
is necessary because if the transmission is driven by the
driveshaft (rear wheels on the ground), no lubricant will reach
the gears and bearings, causing damage to the transmission.
CAUTION: Remove the driveline and axle shafts
or lift the driving wheels off the ground before
towing the vehicle. See “More Driving Tips and
Techniques” on page 96. All lubricating and
clutch application oil pressure is provided by an
engine-driven pump, which will not work when
Operating Instructions
the engine is stopped. You could seriously damage your
vehicle by towing it with the driveline connected and the
drive wheels on the ground.
Worse, when vehicles are towed, either by wrecker or piggyback,
the lubricant in the top front of the drive axle will drain
to the rear. This will leave the top components dry. The resulting
friction may seriously damage them. Always remove the
main driveshaft and axle shafts before towing your vehicle.
