8 Wheel studs

General

BPW Wheel studs
The wheel nave (or wheel disc) connects the rim to Helical fit wheel bolt (Spiral stud)
H the wheel hub. It must absorb the vertical, lateral and
longitudinal forces which arise and transmit them to the
wheel hub via the wheel studs (wheel bolts).
K
BPW axles are suitable for wheels with either stud or hub
centring. BPW axles are supplied with either collar studs
N or spiral studs, depending on the axle type and axle load.

Spiral studs are easy to maintain and connect the brake
drum to the hub using a pressfit. As a result, there is no
need for internal nuts.
The hub bore is not damaged even after several removal/
installation operations (in contrast to the situation with
splined studs) and the clamping forces for the wheel Wheel bolt
studs remain constant.
A collar stud also allows repeated removal and
installation, although it is secured using an internal nut.

The prescribed BPW tightening torques for wheel
attachment are listed in the current BPW maintenance
instructions and must be observed.
