5. Remove valve oil seals using valve oil seal puller (SST).
6. Remove valve spring seats.
7. Before removing valve spring seats, perform valve seat con-
tact check. (Refer to EM-1061.)
8. Before removing valve guides, perform valve guide clear-
ance check. (Refer to below.)
Inspection
CYLINDER HEAD DISTORTION
Using straightedge and feeler gauge, check the bottom of the
cylinder head for distortion.
Limit: 0.2 mm (0.008 in)

VALVE GUIDE CLEARANCE
+Perform the inspection before removing valve guides.
+Check that the valve stem diameter is within specifications.
+Push valve approximately 25 mm (0.98 in) toward combus-
tion chamber, move valve toward dial indicator to measure
valve movement.
+Valve guide clearance is 1/2 of movement on dial indicator.

VALVE SEAT CONTACT
Check valve for any evidence of pitting at valve contact surface,
and reseat or replace if worn out excessively.
+When repairing valve seats, check valve and valve guide
for wear beforehand. If worn, replace them. Then correct
valve seat.
+The cutting should be done with both hands for uniform
cutting.
VALVE SEAT REPLACEMENT
+When removing valve seat, replace it with oversized [0.5 mm
(0.0020 in)] valve seat.
1. Cut valve seat to make it thin, and pull it out.
2. Machine cylinder head inner diameter at valve seat installa-
tion position.
Machining dimension:
Intake
33.500 - 33.515 mm (1.3189 - 1.3195 in) dia.
Exhaust
31.995 - 32.010 mm (1.2596 - 1.2602 in) dia.
3. Heat cylinder head to approximately 110 to 130ÉC (230 to
266ÉF) in oil bath.
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.
5. Using valve seat cutter (multi-purpose tool), finish process-
ing referring to the dimensions 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 satisfac-
tory.

Selection Procedure for Selective Part
Combination
Location Selective part combination Item Method
Cylinder block - pistonPiston and piston assembly
(Part No. is given to a piston
and piston pin as a set.)Piston grade (Piston outer
diameter)Refer to ªSelective combination
chartº.
+Identification grade stamped on each part represents initial
dimension of new part. This grade will not be applied to a
reused part.
+Measure correct dimensions of a reused or modified part,
then refer to ªSelective combination chartº in this manual to
identify the grade.
+Refer to the applicable pages for measurement method for
each part, standards for reuse, and selecting method for
selective part combination.
Disassembly
1. Remove engine assembly from vehicle.
Refer to EM-1064, ªENGINE REMOVALº.
2. Remove pilot bushing from flywheel using pilot bearing puller
(SST), if necessary (M/T model).
3. Install engine to engine stand (SST).
1) Remove flywheel (M/T model) or drive plate (A/T model).
+Using ring gear stopper (SST), secure ring gear, and remove
mounting bolts.
CAUTION:
Do not disassemble flywheel.
+Flywheel has a two-piece structure. When being pressed
forward/backward, or twisted in rotating direction, transmis-
sion-side mass will be moved with audible sound. This is not
a problem.
2) Remove pilot converter (A/T model) and rear plate.

CRANKSHAFT JOURNAL OUTER DIAMETER
Use micrometer to measure journal outer diameter.
Standard: 70.907 - 70.920 mm (2.7916 - 2.7921 in) dia.
CRANKSHAFT PIN OUTER DIAMETER
Use micrometer to measure pin outer diameter.
Standard: 56.913 - 56.926 mm (2.2407 - 2.2412 in) dia.
CRANKSHAFT OUT-OF-ROUND AND TAPER
+Using micrometer, measure each journal and pin at 4 points
shown in the figure.
+Out-of-round value is indicated by difference in dimensions
between directions A and B at points 1 and 2.
+Taper value is indicated by difference in dimensions between
points 1 and 2 in directions A and B.
Out-of-round limit: 0.01 mm (0.0004 in)
Taper limit: 0.01 mm (0.0004 in)
CRANKSHAFT RUNOUT
+Place V-block onto surface plate to support journals at both
ends of crankshaft.
+Position dial indicator vertically onto No. 3 journal.
+Rotate crankshaft to read needle movement on dial indica-
tor.
+Crankshaft bend value is 1/2 of needle movement.
Limit: 0.03 mm (0.0012 in)
