18. INSPECT PACK CLEARANCE OF REVERSE CLUTCH
(a) Install the intermediate shaft on the transaxle rear cover.
(b) Using a dial indicator, measure the direct clutch pack
clearance while applying and releasing compressed air
(392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:0.60−0.82 mm (0.02362−0.03228 in.)
If the pack clearance is less than the minimum, parts may have
been assembled incorrectly, so check and reassemble again.
If the stroke is not within standard, select another flange.
HINT:
There are 6 flanges of different thickness.

19. INSPECT PACK CLEARANCE OF DIRECT CLUTCH &
OVERDRIVE CLUTCH
(a) Using a dial indicator, measure the direct clutch & over-
drive clutch pack clearance while applying and releasing
compressed air (392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:0.61−0.83 mm (0.02401−0.03268 in.)
If the pack clearance is less than the minimum, parts may have
been assembled incorrectly, so check and reassemble again.
If the stroke is not within standard, select another flange.

1. INSPECT PACK CLEARANCE OF FORWARD CLUTCH
(a) Install the forward clutch on the oil pump.
NOTICE:
Be careful not to damage the oil seal ring of oil pump.
(b) Using a dial indicator, measure the forward clutch pack
clearance while applying and releasing compressed air
(392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:1.00−1.25 mm (0.0394−0.4921in.)
If the clearance is not within standard, inspect the discs, plates
and flange.
HINT:
As the opening is large, cover it with a shop rug to prevent the
compressed air from being released.
