Fit
two washers to make

input gear (see Fig. Aa.14), with the chamfered
inside edge
of
one washer towards the gear.

with the
dial test indicator set at zero
transmission side
of
the idler gear. Assemble
Service tool 18G
1089
with a dental wax washer
interposed
on
to the converter housing side
of
the idler gear. To cut the holes in the wax strip,
place the larger washers
of
18G

one on
either side
of
the wax, opposite each other, and
press together.

interposed with a
dental wax washer (Fig. Aa.13).
NOTE.-If
the input gear will not fully mesh
with the idler gear, this indicates that the third speed
reaction gear thrust washer has become displaced.
Therefore
it
is necessary to remove, dismantle, and
reassemble the gear train as detailed in Section Fa.7
1f/t
(all items except
(1)
).
(25)
Screw the two pilot bars
of
Service tool 18G

into the two bottom tapped holes in the crankcase.
Fit
the nylon protector sleeve Service

over the converter output gear and refit the con-
verter housing; tighten into position to the correct
torque figure given in
'GENERAL DATA'. The
input shaft nut must not be fitted.
(26)
Remove the converter housing.
(27) Measure the thickness
of
the idler gear thrust
washer plus the thickness
of
the Service tool
18G
