|7. Check the thickness
of the backplate the plate should be of a suitable
thickness to support the wheel correctly during the grinding
operation without distortion. (See table below)
8. If re-grinding is carried out, care should be taken to
ensure that the dimension X (see diagram below)
is not ground so small that when mounting the disc, the screws
could touch the bottom of the hole. If this did occur, the
wheel nut insert may be pulled out.
|9. All countersunk or counter bored
holes should be uniform to allow for interchange of the fixing
10. Check that the thread nomenclature of the screws conforms
to the nut inserts in the wheel. The screws should be of sufficient
length to properly engage the threads of the inserts but not
too long that they touch the bottom of the hole.
