CHAPTER 5
Place chocks under the trailer wheel opposite to the dismounted one.
Ensure that the trailer is properly secured and will not roll away during wheel
dismounting.
Loosen wheel nuts in the order given in figure (5.3)
Place the jack and raise the trailer on such height that the wheel being
changed does not rest on the ground.
Remove the wheel.
TIP
Wheel nuts should be tightened to 570 Nm - M22x1.5 nuts.
Wheel installation
Clean axle pins and nuts from dirt.
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 trailer, tighten nuts according to recommended torque and given order.
Tightening the nuts
The nuts should be tightened gradually diagonally (in several stages until the required
tightening torque is achieved), using a torque wrench. If you do not have a torque wrench,
The jack used should have adequate load capacity and be technically
sound.
The jack must be placed on a level, solid surface that will not allow it
to penetrate the surface or slip during operation.
If necessary, use properly selected sleepers reducing the unit
pressure of the lift base on the ground, eliminating penetration into the
ground.
Do not lubricate the threads of the nut and pin.
