HORIZONTAL ALIGNMENT CHECK
A
TRANSVERSE DIMENSIONS
==
AA
Width between centres
of
the front
sub-frame front mounting set screws
26 in. (660-4 mm.)
BB
Width between centres
of
the front
sub-frame rear mounting set screws
161-
in. (412'75 mm.)
cc
Width between centres
of
the rear
sub-frame front mounting block lower
set screws
50!
in. (1282-7 mm.)
DD
Width between centres
of
the rear sub-
frame rear mounting block set screws
38!
in. (977'9 mm.)
A preliminary check
of
the alignment can best be carried out by the system
of
diagonals
and
measurement checks from points projected
onto a level floor by means
of
a plumb-bob.
A centre-line
can
then be established by means
of
a large pair
of
compasses and any deviation from correct alignment
will
be evident by
failure
of
the diagonals to intersect
on
the centre-line or by considerable deviations in the measurements.
