INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

3. Remove camshaft sprocket (EXH) bolt and camshaft sprocket
(EXH) (1).
CAUTION:
• Hold the camshaft hexagonal part (A), and then secure the
camshaft.
• Never rotate crankshaft and camshaft separately, so as
not to contact valve with pist on in the following steps.
4. Turn the camshaft sprocket (INT) to the most advanced position. CAUTION:
Installation and removal of the camshaft sprocket (INT) must be done in the most advanced posi-
tion for the following reasons.
• The sprocket (C) and vane ( camshaft coupling) (B) are
designed to spin and move wi thin the range of a certain
angle.
• With the engine stopped and the vane in the most
retarded angle, it will not sp in because it is locked to the
sprocket side by the internal lock pin (A).
• If the camshaft sprocket bolts are turned in the situation
described above, the lock pi n will become damaged and
cause malfunctions because of the increased horizontal
load (cutting force) on the lock pin.
a. Remove camshaft bracket (No. 1) (1). • Loosen the bolts in several steps, and then remove them.
b. Apply the following air pressure to the No. 1 journal oil hole (A) of camshaft (INT) (1) shown using an air gun.
• Apply the air pressure into the oil hole on the second groovefrom the front of camshaft thrust.
• Proceed all the way through step “e” with the air pressure on.

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.
