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 83.500 - 83.510 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).

• 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.
