23) Using the following formula, read the push/pull
gauge, and calculate "N".
N =150 N (15.3 kgf, 33.7 lb) – Z
N: Value indicated on push/pull gauge
150 N (15.3 kgf, 33.7 lb) : Load applied to clutch
plate
Z: Flat board weight
24) Press the center of retaining plate by applying a
force of N using push/pull gauge, and then mea-
sure and record the height A. Measure at three lo-
cations or more 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°.

(B) Drive plate
(C) Retaining plate
25) Install the driven plate, drive plate, retaining
plate and snap ring.
AT Main Case
26) Apply compressed air intermittently to check for
operation.
27) Measure and record the clearance B between
the retaining plate and snap ring. (Reverse clutch)
At this time, do not press down the retaining plate.
B
(A) Thickness gauge
28) Piston stroke calculation
Calculate with A and B dimensions recorded be-
fore. If the calculated value exceeds the service
(C)
limit, replace the drive plate with a new part and ad-
just it within the initial specification.
(B)
T = A + B
(A)
T: Piston stroke
A: Amount of drive plate compression
B: Clearance between retaining plate and snap ring
