NOTE:
If no parts were replaced with new parts that affect
converter end play (items 5, 11, 15, 25, 30, or 35 in
Foldout 7,A) and if the end play recorded in Para-
graph 6–4
a
was 0.025 inch (0.64 mm) maximum,
proceed with Steps (10) through (17). If any of the
listed items were replaced or if the end play record-
ed in Paragraph 6–4
a
was greater than 0.025 inch
(0.64 mm), disregard Steps (10) through (17) and
proceed with Steps (18) through (27).
(10) Install the same color selective thrust
bearing spacer as was removed in Paragraph 6–4
b
(4)
(Figure 6–5).
(11) Using transmission fluid, lubricate the
rear bearing race and install it, flat side first, onto the
spacer (Figure 6–5).
(12) Lubricate the thrust bearing, and install it
onto the bearing race (Figure 6–5).
(13) Using oil-soluble grease, install the front
bearing race, inner lip first, into the hub of converter
cover 5 (Foldout 7,A).
(14) Install sealring 34 into the groove in the
converter pump (Figure 6–4).
(15) Install the converter cover onto the con-
verter pump (Figure 6–4). The balance marks on the
cover and pump must match.
(16) Install twenty-four nuts to retain the con-
verter cover (Figure 6–3). Tighten four of the nuts, at
90 degree intervals, to 10 lb ft (14 N
.
m). Then, tighten
all the nuts to 19–23 lb ft (26–31 N
.
m).
(17) Install a spacer and a spacer retainer
(earlier models) onto each of the six drive studs on
the converter cover (Figure 6–3). Recheck end play
as outlined in Paragraph 6–3
b
. If end play does not
exceed 0.025 inch (0.64 mm), repair is complete. If
end play exceeds this limit, perform the steps in Para-
graph 6–4
b
(1) through (4) and then proceed to Para-
graph 6–4
d
(18).
(18) Install the rear bearing race (Figure 6–5),
flat side first, onto the converter turbine (selective
spacer is omitted). The race should be dry.
(19) Install the thrust bearing (dry) onto the
rear race (Figure 6–5). Install the front bearing race
(dry), inner lip upward, onto the thrust bearing.
NOTE:
The measurements made in Steps (20) through (23)
require that the gauge bar and blocks used (Figure
6–13 through 6–16) be straight and smooth and
have parallel sides. The actual thickness of the bar
and height of blocks are immaterial, but the blocks,
as pairs, must be of equal height.
(20) Position a bar and two blocks as shown
in Figure 6–13. Using a depth micrometer, measure
the distance from the top of the bar to the machined
surface of the converter cover hub. Record this Dimen-
sion as
A
.
(21) Measure the distance from the top of the
bar to the mounting surface of the converter cover (be-
tween bolt holes) as shown in Figure 6–14. Record this
Dimension as
B
.
(22) Position the bar and two blocks as shown
in Figure 6–15. Measure the distance from the top of
the bar to the mounting surface of the converter pump
(between bolts). Record this Dimension as
C
.
(23) Measure the distance (Figure 6–16) from
the top of the bar to the front bearing race installed in
Step (19). Record this Dimension as
D
.
