Match the stamped cylinder number marks (C) on connecting
rod with those on connecting rod cap to install.
23. Tighten connecting rod bolt with the following procedure:
CAUTION:

Make sure that there is no gap in the thrust surface (A) of
the joint between connecting rod (1) and connecting rod
bearing cap (2) and that these parts are in the correct
position. And then, tighten the connecting rod bolts.

If the connecting rod bolts are reused, measure the outer
diameter. Refer to EM-103, "
CONNECTING ROD BOLT
OUTER DIAMETER" .
24. Apply new engine oil to the threads and seats of connecting rod
bolts.
25. Tighten bolts in three steps

After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-95, "CONNECTING ROD SIDE CLEARANCE" .
26. Install oil pan (upper). Refer to EM-24, "
OIL PAN" .
NOTE:
Install the rear oil seal after installing the oil pan (upper).
27. Install rear oil seal. Refer to EM-24, "

If it exceeds the limit, replace connecting rod assembly.
CONNECTING ROD BIG END DIAMETER

Install connecting rod cap (1) without connecting rod bearing
installed, and tightening connecting rod bolts to the specified
torque. Refer to EM-81, "
ASSEMBLY" for the tightening proce-
dure.

Measure the inner diameter of connecting rod big end with an
inside micrometer.

MAIN BEARING CAP BOLT OUTER DIAMETER

Measure the outer diameters (“d1 ”, “d2” ) at two positions as
shown.

If reduction appears in places other than “B” range, regard it as
“d
2 ”.

If it exceeds the limit (a large difference in dimensions), replace
main bearing cap bolt with a new one.
CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter “d” at position as shown.

If reduction appears in a position other than “d”, regard it as “d”.

When “d” exceeds the limit (when it becomes thinner), replace
connecting rod bolt with a new one.
CLOGGED OR DAMAGED OIL FILTER (FOR INTAKE VALVE TIMING CONTROL)

Make sure that there is no foreign material on the oil filter and
check it for clogging.
–Clean it if necessary.

Check the oil filter for damage.
–Replace it if necessary.
FLYWHEEL DEFLECTION (M/T MODELS)

Measure the deflection of flywheel contact surface to clutch with
a dial indicator (A).

Measure the deflection at 210 mm (8.27 in) diameter.

If measured value is out of the standard, replace flywheel.

If a trace of burn or discoloration is found on the surface, repair it
with sandpaper.
CAUTION:
When measuring, keep magnetic fields (such as dial indicator
stand) away from signal plate of the rear end of crankshaft.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION:
Never disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction

Measure the movement amount of thrust (fore-and-aft) direction when 100 N (10.2 kg, 22 lb) force is
added at the portion of 125 mm (4.92 in) radius from the center of flywheel.

7. Pry off drive shaft from transaxle assembly side as shown.

Make sure that circlip is attached on the edge.
CAUTION:

Do not apply an excessive angle to drive shaft joint when
removing from the transaxle.

Do not excessively extend slide joint.

Do not allow drive shaft to hang down. Support the entire
drive shaft.
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in axial direction. Check for any rough movement or significant loose-
ness.

Check boot for cracks or other damage, and for grease leakage.

If damaged, disassemble drive shaft to verify damage, and
repair or replace as necessary.
INSTALLATION
Installation is in the reverse order of removal. Note the following:

Refer to FAX-8, "COMPONENTS" for tightening torque.
CAUTION:
Do not reuse non-reusable parts.

In order to prevent damage to differential side oil seal, place Tool
onto oil seal before inserting drive shaft as shown. Slide drive
shaft into slide joint and tap with a hammer to install securely.

Install new circlip on drive shaft in the circlip groove on transaxle
side. Refer to FAX-12, "
Disassembly and Assembly (Left Side)" .
CAUTION:
Make sure the new circlip on the drive shaft is securely fas-
tened.

After its insertion, try to pull the flange out of the slide joint by
hand. If it pulls out, the circlip is not properly meshed with the
transaxle side gear.
