Inspection procedure
1. Dismantle the rim according to the standard procedures, see
also Safety instructions when working with tyres, group 00.
2. Carefully clean the outside of the rim beadrim bead by using
a wire brush.
3. The wear of the lock ring on the rim bead outside diameter
can produce a mark A. The mark is located between the
ends of the lock ring, see picture.
4. Measure the depth of the wear at this point using av straight
edge and feeler gauge. If the wear exceeds 0,5 mm, the
wheel, the lock ring, and the beadseat or loose flange must
be discarded and replaced with new.
5. If a wear mark is not possible to find, measure the circumfer-
ence of the rim bead using a measuring tape.
6. Calculate the diameter D = Circumference/3.14
7. If the diameter is below the minimum specified, the wheel,
the lock ring and the beadseat or loose flange must be dis-
carded.
Information on the minimum diameter of your rim bead can
be recieved from Kalmar LMV.
