1) Installation of belt tensioner adjuster
(1) Insert stopper pin 1.5 mm (0.059 in) dia. into place
while pushing tension adjuster rod into body using a
press.
CAUTION:
Do not allow press pressure to exceed 9,807 N (1,000
kg, 2,205 lb).
Do not release press pressure until stopper pin is
completely inserted.
Push tension adjuster rod vertically.
Press-in the push rod gradually, taking three min-
utes or more.

5) Check cam face condition; remove minor faults by
grinding with oil stone. Measure the cam height H; replace
if the limit has been exceeded.
Standard:
Intake 41.68—41.78 mm (1.6409—1.6449 in)
Exhaust 41.98—42.08 mm (1.6528—1.6567 in)

6) Measure the thrust clearance of camshaft with dial
gauge. If the clearance exceeds the limit, replace caps and
cylinder head as a set. If necessary replace camshaft.
Standard:

3. Camshaft

B2M0764A
1) Camshaft installation
Apply engine oil to cylinder head at camshaft bearing loca-
tion before installing camshaft. Install camshaft so that
rocker arm is close to or in contact with“base circle”of cam
lobe.
CAUTION:
When camshafts are positioned as shown in figure,
camshafts need to be rotated at a minimum to align
with timing belt during installation.
Right-hand camshaft need not be rotated when set
at position shown in figure.
Left-hand intake camshaft: Rotate 80°clockwise.
Left-hand exhaust camshaft: Rotate 45°counter-clock-
wise.
G2M0752
2) Camshaft cap installation
(1) Apply fluid packing sparingly to cap mating surface.
CAUTION:
Do not apply fluid packing excessively. Failure to do so
may cause excess packing to come out and flow
toward oil seal, resulting in oil leaks.
Fluid packing:
THREE BOND 1215 or equivalent
G2M0753
(2) Apply engine oil to cap bearing surface and install
cap on camshaft as shown by identification mark.
(3) Gradually tighten cap in at least two stages in the
numerical order shown in figure, and then tighten to
specified torque.
(4) Similarly, tighten cap on exhaust side.
After tightening cap, ensure camshaft rotates only
slightly while holding it at“base”circle.
G2M0754
3) Camshaft oil seal installation
Apply grease to new oil seal lips and press onto front end
of camshaft by using ST1 and ST2.
CAUTION:
Use a new oil seal.

(7) Further tighten all bolts by 80 to 90°in numerical
sequence.
CAUTION:
Ensure that the total“re-tightening angle”[steps (6)
and (7) above] do not exceed 180°.
3) Install oil level gauge guide attaching bolt (left side
only).
2. INTAKE MANIFOLD
1) Install camshafts, rocker cover and related parts.

1) Install connecting rod bearings on connecting rods and
connecting rod caps.
CAUTION:
Apply oil to the surfaces of the connecting rod bear-
ings.
2) Install connecting rod on crankshaft.
CAUTION:
Position each connecting rod with the side marked
facing forward.
3) Install connecting rod cap with connecting rod nut.
Ensure the arrow on connecting rod cap faces the front
during installation.
CAUTION:
Each connecting rod has its own mating cap. Make
sure that they are assembled correctly by checking
their matching number.
When tightening the connecting rod nuts, apply oil
on the threads.
