Dismount wheel.
Install wheel
Clean axle pins and nuts of 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 the 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.
INSPECT
•
After the first use of the trailer.
•
Every 2 – 3 hours of trailer use (during the first month of trailer use).
•
Every 30 hours of use.
TIP
Wheel nuts should be tightened using the torque of 510 Nm – M22x1.5 nuts.
