Wheel Nut Tightening - PRONAR T286 Operator's Manual

Pronar T286
Secure castellated nut with cotter pin and mount hub cap.
Delicately tap hub cap with rubber or wooden hammer.
The wheel should turn smoothly without stiffness or detectable resistance not originating from
abrasion of brake shoes in brake drum. Adjustment of bearing slackness may only be
conducted when the trailer is hitched to tractor and the load box is empty.
TIP
If the wheel is dismounted, bearing slackness is easy to check and adjust.
5.2.6 MOUNTING AND DISMOUNTING WHEEL, INSPECTION OF WHEEL NUT
TIGHTENING.
Wheel removal
Immobilise trailer with parking brake.
Place the wheel chocks under the wheel opposite to the dismantled wheel.
Ensure that trailer shall not move during wheel dismounting.
Loosen wheel nuts according to sequence given in figure (5.4).
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.
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.
