Wheel installation
Clean axle pins and nuts of dirt
contamination.
Do not grease thread of nuts and pins.
Check condition of pins and nuts, if
necessary replace.
Place wheel on hub, tighten nuts so that
wheel rim tightly fits the hub.
Lower trailer, tighten nuts according to
recommended torque and given
sequence.
Tightening nuts
Nuts should be tightened gradually diagonally,
(in several stages, until obtaining the required
tightening torque) using a torque spanner. If a
torque spanner is not available, one may use an ordinary spanner. The arm of the spanner
(L) figure (5.5) should be selected according to the weight of the person (F) tightening the
nut. Remember that this method of tightening is not as accurate as the use of a torque
spanner. Tightening of nuts should be checked with the frequency given in the below table.
The activities should be repeated after each removal of a wheel from the wheel axle.
INSPECTION
•
After the first use of the trailer.
•
After the first travel with load.
•
Every 6 months of use or every 25 000 km, whichever occurs first.
•
In the event of intensive work, check the nut tightening at least
every 10,000 km.
TIP
Wheel nuts should be tightened using the torque of 270 Nm - M18x1.5 nuts.
