Wheel stud 6

General

Wheel stud alignment
In stud alignment, the wheel brace (with countersunk
stud holes) is centred using wheel studs with (spring)
centring rings.

Spigot alignment
In spigot alignment, the wheel brace is centred using a
Wheel nuts with rotatable washer Centring bush
centring spigot or ring surfaces on the wheel hub.

Centring bushes may be mounted on two opposing
wheel studs of each hub in the case of wheels with
spigot alignment. This is not necessary, however.
Centring bushes must be mounted on two opposing
wheel studs of each hub in the case of wheels with
mixed centring.

Alloy wheels
In the case of alloy wheels, the wheel brace is centred
using a centring cam or ring surfaces on the wheel hub.
As the fl ange thickness is greater with alloy wheels than
with steel wheels, it is important to check whether the
axles are suitable for fi tting alloy wheels (with 26 mm-
diameter hole).
In the case of twin wheels the available centring seat
and wheel studs must be of adequate length (i.e. the
thread of the wheel nut must be completely engaged
with the wheel bolt thread).
If not, alloy wheels with stud hole Ø 32 can be used in
conjunction with shaft nuts without replacing the hub or
the wheel studs.
(The wheel is not centred by the shaft nuts.)
