Loosen wheel nuts according to sequence shown in figure (5.5).
Place a lifting jack and raise the trailer to a sufficient height so that the wheel
to be replaced does not touch the ground.
The lifting jack should have sufficient lifting capacity and should be
technically reliable.
The lifting jack must be positioned on a level and hard surface so as to
prevent sinking into the ground or relocating the jack during lifting.
If necessary, use proper backing plates in order to reduce unit
pressure of the jack's base on the ground and prevent its sinking into
the ground.
Dismount wheel.
Wheel mounting
TIP
Wheel nuts should be tightened using the torque of 450 Nm - M22x1.5 nuts.
Clean axle pins and nuts of contamination.
Do not grease thread of nuts and pins.
Check condition of pins and nuts, if necessary replace them.
Place wheel on hub, tighten nuts so that wheel rim tightly fits the hub.
Lower the trailer, tighten nuts according to recommended torque and given
sequence.
ATTENTION
Wheel nuts may not be tightened with impact wrench because of danger of
exceeding permissible tightening torque, the consequence of which may be
breaking the thread connection or breaking off the hub pin.
The greatest precision is achieved using a torque spanner. Before commencing
work, ensure that correct tightening torque value is set.
