DISASSEMBLY -- ENGINE REMOVED
.To
measure the
backlash,
set a
dial
gauge against a
tooth on the
driven
shaft
bevel
gear, and move the
gear back and forth while holding the
output
shaft
steady (See Fig. F61)
.
The
difference between
the
highest and the
lowest
gauge reading is the amount of
backlash.
NOTE: Backlash, or gear lash,
is the amount of
move-
ment of one gear
relative
to the
other,
measured with
one gear stationary.
A. Locked
B.
Backlash (total
movement)
C. Dial Gauge Holder (57001-1049)
e
lf the amount of
backlash
is out of the standard range,
replace the shims and
check
the backlash as mentioned
above.

(CD

by 0

mm,
the
backlash will decrease
about
0 .06
mm and vice versa
.
So
the following formula can
be
used to estimate the most
desirable
shim(s)
((D

)
thickness from the
present
shim(s) (

ness, when the backlash is out of the standard range.

Tooth
Contact
Adjustment:
.Appl
y checking compound to 4 or 5 teeth
of
the
driven
shaft
bevel
gear.
NOTES:
1.
Check
to see that there is no
dirt
or oil on
the teeth.
2.
Special
compounds are available from automotive
supply stores for the
purpose
of checking
differential
gear tooth
patterns
and contact. Use this for check-
ing the bevel gears.
3.
The
checking compound must
be
smooth and firm,
with the consistency of tooth paste.
4.
Apply
to the teeth quite thinly with a fairly stiff
paint brush
.
If
painted too thickly, the exact tooth
pattern may not
appear.
.
Turn the output shaft for 3
or
4 revolutions in the
drive
and the reverse (coast) direction,
while
creating
a drag on the
driven
shaft.
e(heck
the
drive pattern
and coast
pattern
of the bevel
gear
teeth.

NOTE: The
tooth contact patterns (of
both
drive
and
coast sides) should
be
centrally located
between the
top
and
bottom of the
tooth.
The drive
side
of
the
driven
shaft is
the convex
side,
and the coast
side
is the concave
side.
.If
correct tooth contact
pattern
cannot
be obtained
,
·replace shims in the following
manner. Then
erase
the
original
tooth contact
pattern,
and check the new
pattern.
Check
the
backlash
every
time
the
shims
are
replaced.
