6.1 MOUNTING AND DISMOUNTING OF THE WHEEL
DISMOUNTING OF THE WHEEL
• Before lifting the wheel that will be re-
moved, loosen the wheel nuts in the
order given in the drawing.
• Place locking wedges on the opposite
side of the disassembled wheel.
• Place the jack under the axle be-
tween the bolts for spring mounting
(see chapter: Preparing the trailer).
The used jack should have
adequate load capacity, it should
be technically sound.
• If necessary, use properly selected
sleepers to reduce the unit pressure
of the elevator base on the ground to
prevent penetration into the ground.
• Raise the trailer to such a height that
the wheel being changed does not
rest on the ground.
• Remove the wheel.
MOUNTING OF THE WHEEL
• Clean the axle pins and nuts from the
dirt with a wire brush. If necessary,
degrease the thread.
Do not lubricate the threads of
the nut and stud
.
• Check technical condition of pins and
nuts, replace if necessary.
• Mount the wheel on the hub, tighten
the nuts so that the rim fits tightly onto
the hub.
• Lower the trailer, tighten the nuts ac-
cording to the recommended torque
and the order given.
