3. Measure crankshaft end play.
Crankshaft end play: mm (in)
Standard
0.05 - 0.18 (0.0020 - 0.0071)
Limit
0.3 (0.012)
If beyond the limit, replace bearing with a new one.
4. Install connecting rod bearings in connecting rods and con-
necting rod caps.
lConfirm that correct bearings are used.
Refer to EM-45.
lInstall bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
lApply new engine oil to bearing surfaces, bolt threads
and seating surfaces.
5. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
lArrange so that front mark on piston head faces toward
front of engine.
lMake sure connecting rod does not scratch cylinder
wall.
lMake sure connecting rod bolts do not scratch crank-
shaft journals.
lApply new engine oil to piston rings and sliding surface
of piston.
b. Install connecting rod bearing caps.
Tighten connecting rod bearing cap nuts using the following
procedure.
Connecting rod bearing nut:
(1) Tighten to 14 to 16 N´m
(1.4 to 1.6 kg-m, 10 to 12 ft-lb).
(2) Tighten bolts 60
+5
þ0degrees clockwise
with an angle wrench.
If an angle wrench is not available, tighten
them to 38 to 44 N´m (3.9 to 4.5 kg-m, 28 to 33
ft-lb).
6. Measure connecting rod side clearance.
Connecting rod side clearance: mm (in)
Standard
0.2 - 0.4 (0.008 - 0.016)
Limit
0.6 (0.024)
If beyond the limit, replace connecting rod and/or crankshaft.

3. Apply oil to the thread portion and seat surface of bolts and
tighten cylinder head bolts using Tool.
CAUTION:
lTightening procedure
1st: Tighten bolts to 39 - 44 Nzm
(4.0 - 4.5 kg-m, 29 - 33 ft-lb).
2nd: Tighten bolts to 59 - 64 Nzm
(6.0 - 6.5 kg-m, 43 - 47 ft-lb).
3rd:
(1) Mark exhaust side of cylinder head and cylin-
der head bolts with paint as shown.
(2) Turn all bolts 90 10 degrees clockwise.
(3) Check that the paint mark of each bolt is fac-
ing the front of the vehicle.
lAlways check the bolt tightening angle with an
angle wrench or protractor. Do not check visu-
ally.
4. Apply engine oil and install push rods.
5. Install rocker shaft assembly.
Adjust intake and exhaust valve clearance tentatively.
Refer to ``Adjusting Intake and Exhaust Valve Clearance'',
``ENGINE MAINTENANCE'' in MA section.
6. Install rocker cover.
lBe sure the ``F'' mark on rocker cover plate faces upward and
is at the front end.
lWhen replacing rocker cover gasket, bend slit of rocker cover
baffle plate a little to hold the gasket. Do not twist gasket.
lTighten all bolts in numeral sequence (as shown in the
figure at left) to the specified torque.
