during the idler and input gear adjustment opera-
tions. Refit the converter housing with a new joint
washer, remove the pilot bars

and
tighten the securing nuts
and
set
screws
to
the torque figures given
in
'GENERAL
DATA'.
(41) Refit the input gear shaft
nut
and
tighten
to
the
correct torque figure (see 'GENERAL DATA)',
using Service tools
180
1088
and
180592.
(42) Remove each pair
of
bolts
in
turn
from the con-
verter and fit new locking plates. Tighten the bolts
to
the torque figure given
in
'GENERAL DATA',
and
tap
up
the locking tabs.
NOTE.-Do
not remove all six screws from the con-
verter centre
at
one time.
(43) Lubricate the converter oil seal
and
refit the con-
verter. Refit the washer (offset pegs)
and
the centre
bolt with its lock washer. Tighten the bolt
to
the
correct torque figure (see 'GENERAL DATA')
with Service tools
180

lock
up
the lock washer.
(44) Refit the low pressure valve

180
1089/1. Substitute this complete assembly for
the input gear on the surface plate (see Fig. Aa.18).
(36) Use the dial test indicator gauge, Service tool
18G
191,
and measure the thickness
of
this assem-
bly (see Fig. Aa.18). The mean reading obtained
indicates the total thickness
of
shims required
to
eliminate end-float. To this figure add shims
to
the
value
of
·001
to
·003
in. ('025 to ·076 mm.) to give
the required input bearing preload.
Input gear adjustment shims
·003 in. (,076 mm.).
·012 in. (,305 mm.).
(37) Measure the thickness
of
the idler gear thrust
washer plus the thickness
of
the Service tool
18G
1089
and its dental wax washer.
From
this
figure subtract ·004 to ·007 in. ('102 to ·178 mm.)
to give the total thickness
of
the thrust washers
to
be fitted to provide the correct idler gear end-
float.
