9. Remove front cover with the following procedure:
a. Loosen bolts in the reverse of the order shown.
b. Cut liquid gasket by prying the position ( ) shown, and then
remove the front cover.
10. Remove front oil seal from front cover. • Remove by lifting it up using a suitable tool.
CAUTION:
Be careful not to damage the front cover.
11. Remove chain tensioner (1) with the following procedure.
a. Fully push down the chain tensioner lever (A), and then push the plunger (C) into the inside of tensioner.
• The tab (B) is released by fully pushing the lever down. As aresult, the plunger can be moved.
b. Pull up the lever to align its hole position with the body hole posi- tion.
• When the lever hole is aligned with the body hole position, theplunger is fixed.
• When the protrusion parts of the plunger ratchet and the tab face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then fix the lever at the upper position.
• The example that a hexagonal wrench for 2.5 mm (0.098 in) is used as shown.
d. Remove chain tensioner.

TIMING CHAIN
12. Remove the timing chain tension guide (2) and the timing chain
slack guide (1).
13. Remove the timing chain (2). • Pull the looseness of timing chain toward the camshaft
sprocket (EXH) (1), and then remove the timing chain (2) and
start the removal from camshaft sprocket (EXH) (1) side.
CAUTION:
Never rotate crankshaft or camshaft while timing chain is
removed. It causes interferen ce between valve and piston.
14. Remove the crankshaft sprocket and the oil pump drive related parts with the following procedure.
a. Remove chain tensioner (1). • Pull out from the shaft (B) and spring fixing holes (A).
b. Hold the top of the oil pump s haft using the TORX socket (size:
E8), and then loosen the oil pump sprocket nut and remove it.
c. Remove the crankshaft sprocket (1), the oil pump drive chain (2), and the oil pump sprocket (3) at the same time.

The illustration shows the relationship between the matching mark
on each timing chain and that on the corresponding sprocket, with
the components installed.
1. Install the crankshaft sprocket and the oil pump drive related parts with the following procedure:
a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
• Install the crankshaft sprocket (1) so that its invalid gear area(A) is towards the back of the engine.
• Install the oil pump sprocket (3) so that its hexagonal surface
faces (B) the front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the TORX socket (size: E8), and then tighten the oil pump sprocket nuts.

c. Install chain tensioner (1).
• Insert the body into the shaft (B) while inserting the spring intothe fixing hole (A) of cylinder block front surface.
• Make sure that the tension is applied to the oil pump drive chain after installing.
2. Install timing chain with the following procedure.
• Install by aligning matching marks on each sprocket and tim-ing chain.
• If these matching marks are not aligned, rotate the camshaft slightly to correct the position.
CAUTION:
• Check matching mark positi on of each sprocket and tim-
ing chain again after instal ling the timing chain, keep
matching marks aligned by holding them with a hand.
• To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
3. Install timing chain tension guide (2) and timing chain slack guide (1).
4. Install chain tensioner (1). • Secure the plunger at the most compressed position using astopper pin (A), and then install it.
• Pull out the stopper pin after installing the chain tensioner.

5. Check matching mark position of timing chain and each sprocket again.
6. Pull out the stopper pin (A), and then apply the tension to the
timing chain by rotating the crankshaft pulley clockwise slightly.
7. Return the camshaft sprocket (INT) in the most retarded position with the following procedure.
a. Remove the stopper pin (A) from the camshaft sprocket (INT).
b. Turn the crankshaft slowly clockwise and return t he camshaft sprocket (INT) to the most retarded angle
position.
• When first turning the crankshaft the camshaft sprocket (INT)
will turn. Once it is turned more, and the vane (camshaft) also
turns, then it has reached t he most retarded angle position.
• The most retarded angle position can be checked by seeing if the stopper pin groove (A) is shifted clockwise.
• After spinning the crankshaft slightly in the counterclockwise
direction, you can make sure the lock pin has joined by seeing
if the vane (camshaft) and the sprocket move together.
8. Install the front oil seal to the front cover. Refer to EM-71, "
FRONT OIL SEAL : Removal and Installation"

TIMING CHAIN
Check for cracks (A) and any excessive wear (B) at link plates and
roller links of timing chain. Replace timing chain as necessary.
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, che ck 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 leakage 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.
