To assist manufacturing
conditions
it is occasionally
necessary
that
a pinion be assembled away
from
the
standard
position. If
this
is so
the
variation
is
marked
on
the
pinion head In a ring such as .(+2),
the
sign
+ meaning
that
the
centres
are
increased by ·002 in.
Correction
has
to
be made for thts, and
when
the
figure is + (plus)
the
amount
must be
taken
from
the
washer
thickness, and if
the
figure Is - (minus)
then
the
amount
has
to
be
added
to
the
washer
thickness.
Example (a) A
washer
fitting
the
gap of
the
dummy
pinlon
with
a marklng
of
·127
must
be
replaced
by a
washer
having
the
marklng ·129
when
reflttl ng a pinIon
with
the
marking
-2
or
-·002.
Example (b) A
washer
fitting
the
gap of
the
dummy
pinion
and
bearing
the
marking
·127
must
be replaced by a
washer
marked
·125
when
the
pinion is
marked
+2
or
+·002
on its head.
A plain
or
unringed
figure may be
marked
on
the
pinion head in addition
to
a ringed figure,
but
this
is
only
an indication
of
the
variation
of
the
pinion
head
thickness
from
standard
and is always minus. It has
no bearing on
the
pinion
setting.
When
the
correct
spacing
washer
has
been
decided
upon
the
actual pinion assembly can
take
place,
but
the
importance
of
making
the
measurements
correctly
must
be
appreciated,
since
it
is
lm-
possible
to
check
the
adjustment
when
the
axle
is
assembled:
