3. Remove cylinder head valve guide hole.
4. Heat cylinder head to 110 to 130°C (230 to 266°F) in oil bath.
5. Using valve guide drift, press fit valve guides from camshaft
side, referring to the dimension shown in the figure.

Valve Seat Contact
●Before starting this check, confirm that the dimension of valve
guide and valves are as specified.
●Apply red lead primer on contacting surfaces of valves seat and
of valve face to examine the conditions of contacting surfaces.
●Check that the paint on contacting surfaces is continuous along
the entire circumference.
●If there are abnormal indications, grind the valve and check the
contact again. If abnormal indications still persist, replace valve
seat.
Valve Seat Replacement
●When removing valve seat, replace it with oversized [0.5 mm (0.020 in)] valve seat.
1. Cut valve seat to make it thin, and pull it out.Valve guide hole diameter (for service parts):
10.175 - 10.196 mm (0.4006 - 0.4014 in)

2. Machine cylinder head inner diameter at valve seat installation
position.
3. Heat cylinder head to approximately 110 to 130°C (230 to

4. After cooling valve seats sufficiently with dry ice, press fit it to cylinder head.
CAUTION:
●Do not touch the cooled valve seats directly by hand.
●Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter, finish processing referring to the dimen-
sions shown in the figure.
CAUTION:
When using valve seat cutter, grasp cutter handle with both
hands, press cutter onto contacting face all around, and cut
thoroughly. If cutter is pressed unevenly or repeatedly, the
valve seat surface may be damaged.
6. Using compound, perform valve fitting.
7. Check again to make sure that contacting status is satisfactory.

●Before and during this lifting, always check if any har-
nesses are left connected.
●During the removal operation, always be careful to pre-
vent vehicle from falling off the lift due to changes in the center of gravity.

ENGINE ASSEMBLY
INSPECTION AFTER INSTALLATION
●Before starting engine check the levels of engine coolant, lubrications and working engine oils. If less than
required quantity, fill to the specified level.
●Before starting engine, bleed air from fuel piping. Refer to FL-16, "Air Bleeding" .
●Run engine to check for unusual noise and vibration.
●Warm up engine thoroughly to make sure there is no leakage of engine coolant, lubricants, working
engine oil, fuel and exhaust gas.
●Bleed air from passages in pipes and tubes of applicable lines.

●Insert a flat-bladed screwdriver between main bearing cap and rear oil seal retainer to remove retainer.
9. Remove rear oil seal from rear oil seal retainer.
●Punch out with a flat-bladed screwdriver.
●Be careful not to damage rear oil seal retainer.
10. Remove piston and connecting rod assembly.
●Before removing piston and connecting rod assembly, check
connecting rod side clearance. Refer to EM-210, "
CONNECT-
ING ROD SIDE CLEARANCE" .
a. Move crankshaft pin to be removed to approximately BDC.
b. Remove connecting rod caps.
c. Using the grip of a hammer, press the piston and connecting rod
assembly out to cylinder head side.
CAUTION:
When removing the piston and connecting rod assembly,
prevent the big end of the connecting rod from interfering
with the oil jet.
11. Remove connecting rod bearings from connecting rods and
caps.
●Keep them by cylinder to avoid confusion.
12. Remove piston rings from pistons using piston ring expander.
CAUTION:
●When removing, prevent pistons from being damaged.
●Do not expand piston rings excessively. This may dam-
age the piston rings.
13. Remove pistons from connecting rods.
a. Using long nose pliers, remove snap rings.

●Install main bearings with the oil holes and grooves onto the
cylinder block side, and those without oil holes and grooves
onto the main cap side.
●While installing bearings, apply engine oil to bearing surfaces
(inside). Do not apply engine oil to rear surfaces, but clean
them completely.
●Align stopper notches on bearings to install them.
●Check that the oil holes on the cylinder block body are mated
with the oil hole positions on the bearings.
5. Install crankshaft to cylinder block.
●Make sure crankshaft rotates smoothly by hand.

●Identify main bearing caps by the punched mark. Install cor-
rectly matching the journal No. on the bearing cap and the
