3. Install valve lifter.
• If it is reused, install in its original positions.
4. Put a matching mark for positioning the camshaft (INT) and the camshaft sprocket (INT) with the following procedure.
NOTE:
It prevents the knock pin from engaging with the incorr ect pin hole after installing the camshaft (INT) and
the camshaft sprocket (INT).
a. Put the matching marks (A) on a line extending from the knock pin position of camshaft (INT) (1) front surface.
• Put the marks on the visible position with the camshaftsprocket installed. (Example shown)
b. Put the matching marks on a line extending from the knock pin hole (B) position of camshaft sprocket (INT) (2). (Example
shown)
• Put the marks on the visible position with it installed to thecamshaft.
5. Install camshafts.
• Distinction between camshaft (INT and EXH) is performed withthe different shapes of rear end.
• Install camshafts to the cylinder head so that knock pins (A) on front end are positioned as shown.
NOTE:
Though camshaft does not stop at the portion as shown, for the
placement of cam nose, it is generally accepted camshaft is
placed for the same direction.
6. Install camshaft brackets (No. 2 to 5) aligning the identification marks on upper surface as shown.
• Install so that identification mark can be correctly read whenviewed from the INT side.

b. Temporarily tighten the camshaft sprocket (INT) bolt on the front side of camshaft sprocket (INT) (1).
c. Hold the camshaft hexagonal part (A), to secure the camshaft and tighten the bolt.
9. Install the camshaft sprocket (EXH) (1) to the camshaft (EXH) while aligning the matching mark (marked when timing chain is
removed) and the matching mark (stamp) of camshaft sprocket
(EXH).
• If the positions of knock pin and pin groove are not aligned,move the camshaft (EXH) slightly to correct these positions.
• Hold the camshaft hexagonal part (A), to secure the camshaft
and tighten the bolt.

INSPECTION AFTER REMOVAL
Cylinder Head Bolt s Outer Diameter
• Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
• If reduction of outer diameter appear s in a position other than “d2”,
use it as “d2” point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-116, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit ), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passag es for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head, measure the distortion in six directions.
• If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.
