6.4.3 AXLE MAINTENANCE AND ADJUSTMENT
6.4.3.1 ASSEMBLY AND FIXING OF THE WHEELS
Above all to check that the type of wheel used is compatible with the nut of the wheel stud, for all the cases of fixing
of the wheel with centering on the wheel stud, i.e. all those of table below except the nuts of the type M, to check
that the holes of the rim have a conical part in order to receive the spherical part as of nuts DIN, the spherical washer
of the plain nuts or the conical part of the nuts with “Bec “.
In the case of twin tires, in order to ensure a good centering, it is necessary to insert a spherical washer between the
flask of the hub and the rim except assembly nuts M.
TIGHTENING OF THE NUTS OF WHEEL
On lately assembled wheels, the nuts can, at the beginning, to loosen up in consequence of a compressing. It is thus
necessary to check the tightening of the nuts after the first course in load. One will proceed in the same way later on
after each disassembling of wheels. To tighten the nuts, use the adapted special wrench. If one uses the machines bolt
wrench for the nuts of wheel, be sure to regulate the tightening torque well, if not the threading and the metal of the
stud and nuts of wheel will undergo an overload.
(*) The 2 last columns of the table are useful as reference for
those which do not have a torque spanner or of pneumatic
screwdriver (see the figure at side).
It is allowed to use an impact wrench for disassembling, but it
is absolutely necessary to avoid the tightening of the nuts
with this type of wrench, because the exerted torque is
unverifiable.
