backlash with a dial indicator
If it IS below the specified value,
replace left washer with a thinner one
and right washer with
a thicker one If
it
is over it, replace left washer with a
ttucker one and right washer with a
thinner one
Note To maintain correct preload at
all tunes, do not change total thick-

Incidentally a decrease or increase
in thickness
of washers causes change
in ring gear-to-pinion ba( klash
Thus, check for proprr backldsh

7 Check and adjust the tooth con.
tact pattern
of ring gear and drive
pinion
(I) Thoroughly clean ring and drive
pinion gear teeth
(2) Paint ring gear teeth lightly and
evenly with a mixture of powdered
ferric oxide and oil of a suitable con-
sistency to produce a contact pattern
(3) Rotate pinion through several
revolutions in the forward and reverse
direLtion until a definite contact pat-
tern is developed
on ring gear
(4) If contact pattern is incorrect,
readjust thickness
of adjusting washer
Be sure to completely wipe off red
lead upon completion
of adjustment
(5) Incorrect teeth contact pattern
'an be adjusted in the following
manner
Contact pattern
a Heel contact
To correct, increase thickness of
pinion height adjusting washer in order
to bring drive pinion close to ring gear
PO193
b Toecontact
To correct, reduce thickness of
pinion height adjusting washer in order
to make drive pinion move away from
ring gear
