Valve Lifter Hole Diameter
Using inside micrometer, measure diameter of valve lifter hole of cyl-
inder head.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (hole diameter of valve lifter) – (outer diam-
eter of valve lifter).
●When out of specified range, referring to each specification of
outer and inner diameter, replace either or both valve lifter and
cylinder head.
Va l v e C l e a r a n c eEBS00LS3
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions due to changes in valve clearance over time (starting, idling, and/or noise).
1. Warm up engine. Then stop it.
2. Remove splash cover on RH undercover.
3. Remove rocker cover. Refer to EM-35, "
ROCKER COVER" .
4. Turn crankshaft pulley in normal direction (clockwise when
viewed from front) to align TDC identification notch (without
paint mark) with timing indicator.
5. At this time, check that the both intake and exhaust cam noses
of No. 1 cylinder face outside.
●If they do not face outside, turn crankshaft pulley once more.
6. By referring to the figure, measure valve clearances at locations
marked X as shown in the table below (locations indicated with
black arrow in figure) with a feeler gauge.
●No. 1 cylinder compression TDC.Standard: 34.000 - 34.021 mm (1.3386 - 1.3394 in)

the figure.
INSPECTION AFTER REMOVAL
Outer Diameter of Cylinder Head Bolts
●Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between d1 and d2
exceeds the limit, replace them with new one.
●If reduction of outer diameter appears in a position other than
d2, use it as d2 point.
INSTALLATION
1. Install cylinder head gasket.
2. Follow the steps below to tighten fixing bolts in the order shown
in figure to install cylinder head.
CAUTION:
●If cylinder head bolts are re-used, check their outer diam-
eters before installation. Refer to EM-61, "
Outer Diameter
of Cylinder Head Bolts" .
●In step “c”, loosen bolts in the reverse order of that indi-
cated in figure.
a. Apply new engine oil to threads and seating surface of mounting
bolts.
b. Tighten all bolts to 98.1 N·m (10 kg-m, 72 ft-lb).
c. Completely loosen to 0 N·m (0 kg-m, 0 ft-lb).
d. Tighten all bolts to 34.3 to 44.1 N·m (3.5 to 4.5 kg-m, 26 to 32 ft-lb).
e. Turn all bolts 75° to 80° (target: 75°) degrees clockwise.

wrench or protractor. Avoid judgment by visual inspection
without the tool.

Disassembly and AssemblyEBS00KNR
CAUTION:
●When installing camshafts, chain tensioners, oil seals or other sliding parts, lubricate contacting
surface with new engine oil.
●Apply new engine oil to threads and seat surface when installing cylinder head, camshaft
sprocket, crankshaft pulley and camshaft bracket.
●Attach tags to valve lifters so as not to mix them up.

12. Install the connecting rod bearings to the connecting rod and the
connecting rod cap.
●When installing the connecting rod bearings, apply engine oil
to the bearing surface (inside). Do not apply engine oil to the
back surface, but thoroughly clean it.
●When installing, align the connecting rod bearing stopper pro-
trusion with the notch of the connecting rod to install.
●Check the oil holes on the connecting rod and those on the
corresponding bearing are aligned.
13. Install the piston and connecting rod assembly to the crankshaft.
●Position the crankshaft pin corresponding to the connecting
rod to be installed onto the bottom dead center.
●Apply engine oil sufficiently to the cylinder bore, piston and
crankshaft pin.
●Match the cylinder position with the cylinder No. on the con-
necting rod to install.
●Using a piston ring compressor, install the piston with the front
mark on the piston crown facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big end.
14. Install the connecting rod cap.
●Match the stamped cylinder number marks on the connecting
rod with those on the cap to install.
15. Tighten the connecting rod bolt as follows.
a. Apply engine oil to the threads and seats of the connecting rod
bolts.
b. Tighten bolts to 18.6 to 20.6 N·m (1.9 to 2.1 kg-m, 14 to 15 ft-lb).
c. Put mating (with paint) on each bolt and connecting rod cap, all
in the same direction (when using a protractor).
d. Then tighten all bolts 90 to 95 degrees clockwise (target: 90
degrees) (Angle tightening).
CAUTION:
Always use either an angle wrench or protractor. Avoid
tightening based on visual check alone.
●After tightening the bolt, make sure that the crankshaft rotates smoothly.
●Check the connecting rod side clearance. Refer to EM-89, "CONNECTING ROD SIDE CLEARANCE" .

ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
14. Remove chain tensioner.
