Place the wheel chocks under the wheel opposite to the dismounted wheel.
Ensure that trailer shall not move during wheel dismounting.
Loosen wheel nuts according to sequence shown in figure (5.2).
Place a lifting jack and raise the trailer to a sufficient height so that the wheel
to be replaced does not touch the ground.
Dismount wheel.
Wheel mounting
Clean axle pins and nuts of contamination.
Check condition of pins and nuts, if necessary replace them.
Place wheel on hub, tighten nuts so that wheel rim tightly fits the hub.
If possible, wheels should be dismounted when the trailer is not
loaded.
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.
Do not grease thread of nuts and pins.
