22) Install the planetary gear and low clutch as-
sembly to the transmission case.
NOTE:
Install carefully while rotating the low clutch and
planetary gear assembly slowly, being careful not
to damage the seal ring.
23) Measure the amount of drive plate compres-
sion and record that value. (Non-turbo model)
(1) Place the dish plate, driven plate, drive plate
and retaining plate neatly in this order on sur-
face table.
(2) Set the dial gauge to the clutch, and read its
scale.
NOTE:
The value, which is read in the gauge at this time, is
zero point.
(3) Scale and record the weight “Z” of the flat
board that will be placed on the retaining plate.
NOTE:
• Use a stiff board which does not bend against
load as a flat board to be put on retaining plate.
• Use a flat board weighing less than 10.2 kg (22.5 lb).
(4) Put the flat board on retaining plate.
(5) Using the following formula, read the push/
pull gauge, and calculate “N”.
N = 100 N (10.2 kgf, 22.5 lb) – Z
N: Value indicated on push/pull gauge
100 N (10.2 kgf, 22.5 lb) : Load applied to clutch
plate
Z: Flat board weight
(6) Press the center of retaining plate with a
force of N using a push/pull gauge, and mea-
sure and record height “A”. Measure at three or
more locations spaced by equal distances and
take the average value.
NOTE:
If measuring in three locations, measure every
120°. If measuring in four locations, measure every
90°.
24) Install the pressure rear plate, 2-4 brake drive
plate, driven plate, retaining plate and snap ring.
