Prolonged and repeated contact with engine oil will harm your skin. If engine oil is spilled on your skin, wash it
off immediately with water. In addition, used engine oil contains potentially harmful contaminants which may
cause skin cancer. Always use adequate skin protection when performing vehicle service.
CAUTION:
When servicing the oil filter, install the special tool against the base of the filter to avoid deforming
the filter.
1. Start the engine and allow it to warm up to normal operating temperature.
2. Stop the engine and remove the engine oil filler cap.
3. Raise and support the vehicle.
4. Remove the oil pan drain plug and drain the oil out of the engine.

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 A and B. Top measurement should be 12 mm down and
bottom measurement should be 12 mm up from
bottom of bore.
CYLINDER BORE
Cylinder Size 86.50 - 86.53 mm
Cylinder Cylindrically ≤0.01 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.

•Measure the following dimensions of each piston
(1), piston pin (2) and connecting rod (3).
Length of piston pin in hole (A).
Width of pin sockets (B).
Length of piston pin (C).
Width of small end of connecting rod (D).
• Put measured sizes above into following formula to
calculate L.
L=[(A-C)-(B-D)] / 2
• After inserting the push rod of the special tool into piston pin, install pipe A in the top of the push rod.
• Install forward marks of piston and connecting rod in the same direction.
• Lubricate the external diameter of piston pin with engine oil.
• Through pipe A, insert the push rod, piston pin and pipe component into piston pin hole from the side with the
forward mark.
• Screw on guide block B into guide pipe A to gain clearance between guide block A (2) and guide block B (1)
equal to the value of Value L (L=[(A-C)-(B-D)] / 2)
plus 3 mm.
• Keep the forward mark of piston upward. Install piston and connecting rod in tool base of piston pin installer.

Bearing Oil Clearance (Plastigauge)
•Check the oil clearance of the connecting rods and crankshaft.
Clean all engine oil off of the connecting rod bearing and the crankshaft journal.
Cut the plastigauge into lengths as wide as the crankshaft journal.
Lay the plastigauge across the crankshaft
journal.
Carefully install the connecting rod cap.
Torque the connecting rod cap nuts to 20 N·m
Carefully disassemble the connecting rod cap.
Use the measuring rule imprinted on the plas- tigauge package to measure the width of the
widest part of the plastigauge.
