Inspection
NOTE :
All measurements should be taken with the engine block at room temperature, 21°C.
Engine Block
•Clean cylinder block thoroughly and check all core hole plugs for evidence of leaking.
• Examine block and cylinder bores for cracks or fractures.
• Check block deck surfaces for flatness. Deck surface must be within service limit of 0.050 mm.
Cylinder Bore
• The cylinder walls should be checked for out-of-round and taper with cylinder indicator or equivalent. If the cyl-
inder walls are badly scuffed or scored, the cylinder block should be replaced, and new pistons and rings fitted.
• Measure the cylinder bore at three levels in directions X and Y. Top measurement should be 10 mm down and
bottom measurement should be 10 mm up from
bottom of bore.
CYLINDER BORE
All Cylinders 81.000 - 81.010 mm
Assembly
NOTE :
Cleanliness is extremely important during the engine assembly procedure. Any foreign material, including any mate-
rial created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause
engine failure.
NOTE :
Assemble all components in their original position.
1. Install the pistons to the connecting rods.
2. Using a piston ring expander, install the piston rings.
3. Assemble all components in the reverse order of disassembly.

•Piston Ring Removal
Using a suitable ring expander, remove upper
and intermediate piston rings.
Remove the upper oil ring side rail, lower oil ring side rail and then oil ring expander from
piston.
Clean ring grooves of any carbon deposits.
CAUTION:
Before removing the piston rings (1), check the
piston ring side clearance. Be careful to mark
the location of the piston rings if they are to
be reused.
• Piston Pin Snap Ring Removal
Using snap ring pliers, remove the snap ring
(1).
Heat the pistons if necessary.

CYLINDER BORE
All Cylinders 81.000 - 81.010 mm
Check piston ring to groove side clearance.
• Clean the ring slot using a suitable tool.
• Measure piston ring to groove side clearance.
RING GROOVE CLEARANCE
First Ring 0.04 - 0.08 mm
Second Ring 0.01 - 0.0251 mm
• Wipe the cylinder bore clean. Insert ring and push down with piston to ensure it is square in the bore. The ring
gap measurement must be made with the ring posi-
tioned at least 13 mm from bottom of cylinder bore
and below the bottom of the oil ring travel where
the cylinder bore has minimal wear. Check gap with
feeler gauge.

•Check the radial clearance of connecting rod bearing.
CONNECTING ROD RADIAL CLEARANCE
Radial Clearance 0.016 - 0.051 mm
Assembly
NOTE :
The rod bolts should not be reused.
1. Before installing the NEW rod bolts, the threads and under the bolt head should be oiled with clean engine oil.
2. Install each bolt finger tight, then alternately tighten each bolt to assemble the cap properly.
3. Tighten the connecting rod bolts using the two step torque-turn method:• 1st Step: Tighten bolts to 25 N·m
• 2nd Step: Tighten the connecting rod bolts an
additional 90°
4. Using a feeler gauge check connecting rod side clearance. •Check axial clearance of connecting rod.

•The crankshaft main journals should be checked for
excessive wear, roundness and scoring. Limits of
roundness on any crankshaft main journals should
be held to 0.008 mm. Limits of roundness on any
crankshaft rod journals should be held to 0.005
mm. DO NOT nick crank pin or bearing fillets. Lim-
its of out of round on any crankshaft journals
should be held to 0.005 mm.
• Check the axial clearance after installation. Stan-
dard of axial clearance should be 0.07 mm. Limits
of axial clearance should be held to 0.265 mm.
• Clean the journal and bearing.
• Install the crankshaft.
• Cut the plastic-gauge to the same width as the
bearing, and then put it onto the crankshaft journal
to make it parallel with the central line of the crank-
shaft.
• Install the main bearing cap carefully, and tighten
the bolts to the specified torque.
• Remove the main bearing cap.
• Measure the oil clearance with the plastic-gauge.
Standard oil clearance of crankshaft rod and
main journals should be 0.022 mm
Limits of oil clearance of crankshaft rod and main journals should be 0.058 mm
Standard oil clearance of crankshaft main journal
should be 0.022 mm. Limits of oil clearance of crank-
shaft main journal should be 0.058 mm.
