• Secure crankshaft pulley with a suitable tool and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark (B) on crankshaft pulley, mating with any one of six easy to recognize angle marks (A) on crankshaft bolt flange
(1).
d. Turn another 60 degrees clockwise (angle tightening). • Check the tightening angle with movement of one angle mark.
10. Check that crankshaft turns smoothly by rotating by hand clockwise using suitable tool.
11. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there are no lea ks 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.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

2. Remove camshaft sprocket (EXH) (1).
CAUTION:
• Hold the camshaft hexagonal pa rt (A), and then secure the
camshaft.
• Do not rotate crankshaft and camshaft separately, so as not to contact valve with piston.
NOTE:
The timing chain with the front cover installed is not disengaged
from the crankshaft sprocket and it is not dropped into the front
cover. Therefore, the timing chain tension holding device is not
necessary.
3. 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. Make sure to follow the procedure exactly.
• 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.
• Put the camshaft sprocket (INT) in the most advanced position:
a. Remove camshaft bracket (No. 1) (1). NOTE:
Timing chain is present only for illustration purposes. Timing
chain is to be removed during removal procedure.
• 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 groove
from the front of camshaft thrust (B).
• Proceed all the way through step “e” with the air pressure on.
• Attach the rubber nozzle narrowed to the top of the air gun to prevent air leaks from the oil hole (A). Securely apply the air
pressure to the oil hole.
WARNING:
Eye protection should be worn as needed.
CAUTION:
• There are other oil holes in the side gr ooves. Do not use the incorrect oil holes.

4. Remove the camshaft sprocket (INT):
a. Keeping the camshaft hexagonal part (A) in place using suitable
tool, loosen the bolts for the camshaft sprocket (INT) (2).
CAUTION:
• Do not drop stopper pin.
• Tape (C) the stopper pin (B) so it does not come out.
• Do not subject it to impact by dropping.
• Do not disassemble. [Do not loosen the three bolts (A)].
NOTE:
While removing the camshaft sprocket (INT), if you have taken
out the stopper pin and the lock pin has been rejoined in the
most retarded angle, do the following to restore it.
i. Install the camshaft (INT) and tighten the bolts enough to pre- vent air from leaking out.
CAUTION:
The internal lock pin will ge t damaged, so keep the torque
on the bolts to the minimum required to prevent air from
escaping.
ii. Apply the air pressure, disengage the lock pin, and turn the vane to the most advanced angle position.
iii. Insert the stopper pin.
iv. Remove camshaft sprocket (INT) from the camshaft.
5. Remove camshaft brackets (No. 2 to 5). • Loosen bolts in several steps in the reverse order as shown.
NOTE:
The camshaft bracket (No. 1) has been already removed.
6. Remove camshaft (EXH).
7. Remove camshaft (INT).
8. Remove valve lifter (if necessary). • Identify installation positions, and store lifters without mixing them up.
9. Remove the generator and bracket. Refer to CHG-29, "

Oil Filter
• Check that there is no foreign material on the oil filter (1) and check it for clogging.
• Check the oil filter for damage.
• If there is some damage, replace the oil filter, the plug, and the washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set a suitable tool vertically to No. 3 journal.
3. Turn camshaft to one direction, and measure the camshaft runout using suitable tool. (Total indicator reading)
