(6) While pressing the direct clutch flange with a force of 9.8 -
29.4 N (1.0 - 3.0 kgf), using the following SST (A) in com-
bination with a suitable pushable gauge, measure the end
play between the direct clutch flange and the snap ring,
using a flat thickness gauge (B).
Specified Value:
SST:
09306-87302-000 ... (A)
(7) Confirmation of turning effort of clutch disc
Insert the input shaft (forward clutch) and rotate it. At this
time, ensure that the clutch disc rotates lightly.
(8) Measure the bush inner diameter of the direct clutch pis-
ton subassembly, using an inner caliper gauge.
Specified Value:
Allowable Limit:
NOTE:
•
Ensure that the measurement should be performed at
several points.
•
If the measured value exceeds the allowable limit, re-
place the direct clutch drum subassembly with a new
one.
•
If the measured value exceeds the allowable limit of
the bush inner diameter, check the bush contacting
surface of the stator shaft of the oil pump assembly. If
the contacting surface is scratched or discolored, re-
place the stator shaft & oil pump assembly with a new
one, too.
3. Forward clutch assembly
•
Operation check of forward clutch piston
(1) Secure the input shaft on a vice with aluminum sheets
interposed.
NOTE:
•
Be very careful not to score the bush contacting sur-
face of the input shaft.
(2) Blow compressed air of 392 - 784 kPa (4 - 8 kgf/cm
into the fluid hole of the input shaft indicated in the
right figure. At this time, check that the piston slides
smoothly.
