are
supplied
as matched

PINION
Where
the old
pinion
and
bearings
are
serviceable and
the
tooth
contact
turning
torque
and backlash
checks
made on
dismantling
are
satisfactory
then
assembly
is a
reversal of
the
dismantling procedure
If
any
of the
above factors
proved
incorrect
on the
check
it will
be
necessary
to
carry
out
the
appropriate
adjustment
as
described
in this section
This
is
not the case however when
a
new
pinion
and
crownwheel
is
to be installed and or the
bearings
renewed
Adjustment
of
the
pinion
positiori
and
bearing pre
load
then
becomes
essential
There are
two methods
of
obtaining
the
correct
pinion
position
which
is
regulated by
the shims located
between
the rear
bearing
outer
cup
and the carrier
One method
requires
the use of an
arbor
and
gauge
kit to
calculate
the
thickness of
shim
required
The
second
method entails the
alteration of the
existing
shims thickness
to
comperisate
for
the
new
pinion
head variation
using
the old
pinion
head
variation as a
guide
Note
that the
pinion
head variation
from standard
figures
is
given
in units
of 0 00
