1. Cylinder Head Cover
Lightweight yet high-strength aluminum cylinder head covers are used.
An oil delivery pipe is installed inside the cylinder head cover. This ensures lubrication to the sliding parts
of the roller rocker arm, improving reliability.
2. Cylinder Head Gasket
A steel-laminate type cylinder head gasket is used. A shim is used around the cylinder bore of the gasket to
help enhance sealing performance and durability.

8. Crankshaft Bearing and Crankshaft Bearing Cap
The crankshaft bearing is made of aluminum alloy.
As the connecting rod bearings, the lining surface of the crankshaft bearings is micro-grooved to realize
an optimal amount of oil clearance. As a result, cold-engine cranking performance is improved and engine
vibration is reduced.
The upper main bearing has an oil groove around its inside circumference.
The crankshaft bearing caps are tightened using 4 plastic region tightening bolts for each journal. In
addition, each cap is tightened laterally to improve its reliability.
9. Crankshaft Pulley
The rigidity of the crankshaft pulley with its
built-in torsional damper rubber reduces noise.

INSPECTION
1. INSPECT DIFFERENTIAL SIDE GEAR BACKLASH
(a) Using a dial indicator, measure the backlash of the
side gear.
Standard backlash:
0.05 to 0.20 mm (0.0020 to 0.0070 in.)
Standard thrust washer thickness:
1.625 mm (0.0640 in.)
1.725 mm (0.0679 in.)
1.825 mm (0.0719 in.)
REASSEMBLY
1. INSTALL FRONT DIFFERENTIAL SIDE GEAR
(a) Coat the 2 front differential side gears, 2 side gear
thrust washers, 2 front differential pinions and 2
pinion thrust washers with ATF and install them to
the differential case.
2. INSTALL NO. 1 FRONT DIFFERENTIAL PINION
SHAFT
(a) Coat the No. 1 front differential pinion shaft with

AX–248U241E AUTOMATIC TRANSAXLE – UNDERDRIVE CLUTCH
AX
INSPECTION
1. INSPECT UNDERDRIVE PACK CLEARANCE
(a) Install the underdrive clutch to the transaxle case.
NOTICE:
Be careful not to damage the oil seal rings.
(b) Install a dial indicator as shown in the illustration.
(c) Measure the underdrive clutch pack clearance while
applying and releasing compressed air (392 kPa,
4.0 kgf/cm
2, 57 psi).
Standard pack clearance:
1.51 to 1.90 mm (0.0594 to 0.0748 in.)
If the pack clearance is not as specified, inspect the
discs, plates and flange.
2. INSPECT NO. 1 UNDERDRIVE CLUTCH DISC
(a) Check to see if the sliding surface of the disc, plate
and flange are worn or burnt. If necessary, replace
them.
HINT:
• If the lining of the disc is peeling off or discolored,
or even if a part of the printed mark is defaced,
replace all discs.
• Before assembling new discs, soak them in ATF
for at least 15 minutes.
3. INSPECT UNDERDRIVE CLUTCH RETURN SPRING
SUB-ASSEMBLY
(a) Using a vernier caliper, measure the free length of
the spring together with the spring seat.
Standard free length:
17.14 mm (0.6748 in.)

• This prevents the spring sheet from being
deformed.
• Do not expand the snap ring excessively.
3. INSTALL NO. 1 UNDERDRIVE CLUTCH DISC
(a) Install the 3 plates, 3 discs and flange.
Install in order:
P - D - P - D - P - D - F
HINT:
P = Plate
D = Disc
F = Flange
(b) Using a screwdriver, install the snap ring.
(c) Check that the end gap of the snap ring is not
aligned with one of the cutouts.
4. INSPECT UNDERDRIVE PACK CLEARANCE
(a) Install the underdrive clutch to the transaxle case.
NOTICE:
Be careful not to damage the oil seal rings.
(b) Set a dial indicator as shown in the illustration.
(c) Measure the underdrive clutch piston stroke while
applying and releasing compressed air (392 kPa,
4.0 kgf/cm
2, 57 psi).
Standard pack clearance:
1.51 to 1.90 mm (0.0594 to 0.0748 in.)
If the pack clearance is less than the minimum,
parts may have been assembled incorrectly, so
check and reassemble again.
If the park clearance is not as specified, select
another flange.
HINT:
There are 3 flanges in different thickness.
