lWhen installing flywheel to crankshaft, be sure to correctly
align crankshaft side dowel pin and flywheel side dowel pin
hole.
CAUTION:
If these are not aligned correctly, engine runs roughly
and “MI” turns on.
lThere is a mating mark on the clutch cover side of flywheel.
Refer it during installation.
lHolding ring gear with ring gear stopper [SST], tighten secur-
ing bolts with TORX socket (size: T55, commercial service
tool).
lTighten bolts uniformly in a crisscross manner.
–If these are not aligned correctly, engine runs roughly and “MI” turns on.
25. Install drive plate (A/T models).
lWhen installing drive plate to crankshaft, be sure to correctly align crankshaft side dowel pin and drive
plate side dowel pin hole.
CAUTION:
If these are not aligned correctly, engine runs roughly and “MI” turns on.
lInstall drive plate and reinforcement plate as shown in the fig-
ure.
lHolding ring gear with ring gear stopper [SST: KV10105630],
tighten securing bolts with TORX socket (size: E20) (commer-
cial service tool).
lTighten bolts uniformly in a crisscross manner.
26. Install in the reverse order of removal.

How to Select Piston and BearingEBS01E6F
DESCRIPTION
lThe identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
lFor reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
lFor details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
HOW TO SELECT PISTON
When Using New Cylinder Block
1. Identify the cylinder bore grade (No. 1, 2, or 3) on LH surface at
the rear of cylinder block.
2. Select piston of the same grade.
lThe part No. of piston is specified together with piston pin as
an assembly.
When Re-using an Old Cylinder Block
1. Measure cylinder bore inner diameter. Refer toEM-129, "Cylinder Bore Inner Diameter".
2. Referring to “Cylinder bore inner diameter” in “Piston Selection Table”, determine the bore grade.
3. Select piston of the same grade.
