drive units will be fitted to and mark the
centre point. Hint: Measure this point

the centre of the cross member using a
tape measure.
III. Now take the Drive Unit Brackets (3),
apply Grease on the underside of these
brackets and position onto the cross
member, do not bolt down just yet. Hint:
The angle of the brackets should be
facing inward.
IV. Measure the centre to centre distance
using the centre of the holes on top of
the brackets. The centre to centre
distance should match that
recommended in the Accreditation Pack.
