PISTON RINGInstall the No. 2 piston ring and then the No. 1 piston ring
with a piston ring expander.
Caution
1. The No. 1 and No.2 piston rings have a different
cross section. Be sure to install them in correct
positions.
2.Install the No. 1 and No.2 piston rings with the size
mark and maker mark on ring surface toward the
piston top.
4. INSTALLATION OF PISTON AND CONNECTlNG ROD
ASSEMBLY(1) Liberally coat engine oil on the circumference of the
piston, piston ring, and oil ring.
(2) Arrange the piston ring and oil ring gaps (side rail and
spacer) as shown in the figure.
(3) Rotate crankshaft so that crank pin is on center of
cylinder bore.

bltab notches
DEN057(4) Use suitable thread protectors on connecting rod bolts
before inserting piston and connecting rod assembly
into cylinder block. Care must be taken not to nick crank
pin.(5) Using a suitable piston ring compressor tool, install
piston and connecting rod assembly into cylinder block.
Caution
Insert the front mark (arrow) on the top of the
piston so it faces the engine front (timing belt side).
2. INSTALLATION OF CONNECTING ROD CAPLining up the marks put at the time of disassembly, install
the connecting rod cap on the connecting rod.
If the connecting rod is new without such marks, position
the bearing block tab notches in rod and cap on the same
side as illustrated.
. CHECKING CONNECTING ROD BIG END SIDE CLEAR-
ANCE
Connecting rod big end side clearance:
0.1-0.25 mm (.0039-.0098 in.)
Limit: 0.4 mm (016 in.)

RING GEAR (Engine with a manual transaxle)Check the ring gear for worn, damaged or broken teeth.
Replace the ring gear if teeth are faulty, and also check the
starter motor pinion.
Ring Gear Replacement Procedure(1) Strike outer circumference of ring gear at several points.
Caution
The ring gear cannot be removed if it is heated.(2) Install the ring gear on flywheel after heating the ring gear
to
260-280°C (500-536°F) for shrink fit.
FLYWHEEL (Engine with a manual transaxle)
(1) Visually check the clutch disc friction surface of flywheel forridge wear, streaks and seizure. Replace as necessary.
(2) If the flywheel
runout exceeds the limit, replace it.
Limit: 0.13 mm (0051 in.)
DRIVE PLATE (Engine with an automatic transaxle)Replace if deformed, damaged or cracked.

15. INSTALLATION OF UPPER BEARINGWhen reusing the main bearings, install them in their
original positions by referring to location marking made at
the time of removal.
Be sure that oil holes in bearings align with those in cylinder
block.
13. INSTALLATION OF LOWER BEARINGMake sure that a bearing without oil groove is used as
lower bearing.
12. INSTALLATION OF BEARING CAP(1) Install the bearing caps with their arrow mark directed
toward the timing belt side of engine. Cap numbers
must be in correct order.(2) Tighten cap bolts in the sequence of center,
No.2,
No.4. front and rear cap bolts.
(3) Cap bolts should be tightened evenly in 2 to 3 steps
before they are finally tightened.
(4) Make certain that the crankshaft turns freely and has a
proper end play by checking the clearance between
center main bearing thrust flange and connecting rod
big end bearing.
Crankshaft end play:
0.05-0.18 mm (.0020-.0071 in.)
Limit:0.25 mm (.0098 in.)
