INSPECTION AFTER REMOVAL
Camshaft Runout
●Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
●Set dial gauge vertically to No. 3 journal.
●Turn camshaft to one direction with hands, and measure cam-
shaft runout on dial gauge. (Total indicator reading)
Camshaft Cam Height
1. Measure camshaft cam height.
2. If wear is beyond the limit, replace camshaft.
Camshaft Journal Clearance
Outer Diameter of Camshaft Journal
Measure outer diameter of camshaft journal.
Inner Diameter of Camshaft Bracket
●Tighten camshaft bracket bolt with specified torque.
●Using inside micrometer, measure inner diameter of camshaft
bracket.
Calculation of Camshaft Journal Clearance
(Journal clearance) = (inner diameter of camshaft bracket) – (outer
diameter of camshaft journal).
●When out of the specified range above, replace either or both camshaft and cylinder head.
NOTICE:
Inner diameter of camshaft bracket is manufactured together with cylinder head. Replace the whole cylin-
der head assembly.Standard: Less than 0.02 mm (0.0008 in).

CYLINDER HEAD
5. Install valve spring.
●Install smaller pitch (valve spring seat side) to cylinder head
side.
●Confirm identification color of valve spring.
6. Install valve spring retainer.
7. Install valve collet.
●Compress valve spring with valve spring compressor. Install
valve collet with magnet hand.
●Tap stem edge lightly with plastic hammer after installation to check its installed condition.
8. Install valve lifter.
9. Install spark plug tube.
●Press fit it into cylinder head as follows.
a. Remove old liquid gasket from cylinder head side mounting
hole.
b. Apply liquid gasket all round on spark plug tube with a 12 mm
(0.47 in) width from edge of spark plug tube on the press fit side.
Use Genuine Liquid gasket or equivalent.
c. Using a drift (commercial service tool), press fit spark plug tube
so that height is as same as H shown in figure.
CAUTION:
●When press fitting be careful not to deform spark plug tube.
●After press fitting, wipe off any protruding liquid gasket on top surface of cylinder head.
10. Install spark plug with spark plug wrench.
Inspection After DisassemblyEBS00KNS
CYLINDER HEAD DISTORTION
1. Wipe off engine oil and remove water scale (like deposit), gas-
ket, sealer, carbon, etc with scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter pas-
sages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure distortion in six directions.
VALVE DIMENSIONS
Check dimensions of each valve. For dimensions, refer to SDS, EM-
99, "Valve Dimensions" . Intake : Blue

CYLINDER BLOCK
Method of Using Plastigage
●Remove engine oil and dust on the crankshaft journal and the
surfaces of each bearing completely.
●Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
●Tighten the main bearing bolts to the specified torque.
CAUTION:
Never rotate the crankshaft.
●Remove the bearing cap and bearings, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in “Method of Measurement”.
MAIN BEARING CRUSH HEIGHT
●When the bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude.
●If the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK MOUNTING BOLT
●Perform only with M10 (0.39 in) bolts.
●Measure outer diameters (d1, d2) at two positions shown in the figure.
●Measure d2 at a point within block A.
●When the value of d1- d2 exceeds the limit (a large difference in
dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
●Measure outer diameter (d) at position shown in the figure.
●When “d ” exceeds the limit (when it becomes thinner), replace
the bolt with a new one.
