TIMING CHAIN
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 so that its invalid gear area (A)
is towards the back of the engine.
 Install the oil pump sprocket 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.

TIMING CHAIN
Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-19, "
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.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.A: Crack
B: Wear

CAMSHAFT
 The sprocket (C) and vane (camshaft coupling) (B) are
designed to spin and move within the range of a certain
angle.
 With the engine stopped and the vane in the most
retarded angle, it will not spin because it is locked to the
sprocket side by the internal lock pin (A).
 If the camshaft sprocket mounting bolts are turned in the
situation described above, the lock pin will become dam-
aged 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 groove
from the front of camshaft thrust (B).
 Proceed all the way through step “e” with the air pressure on.
 Attach the rubber nozzle (B) narrowed to the top of the air gun
(A) to prevent air leakage from the oil hole. Securely apply the
air pressure to the oil hole.
CAUTION:
 There are other oil holes in the side grooves. Never use
the incorrect oil holes.
 Be sure not to damage the oil path with the tip of the air
gun.
 Wipe all the oil off the air gun to prevent oil from being
blown all over along with the air, and the area around the
air gun should be wiped with a rag when applying air
pressure. Eye protection should be worn as needed.
NOTE:
The air pressure is used to move the lock pin into the disengage position.
c. Hold the camshaft sprocket (INT) with hands, and then apply the power counterclockwise/clockwise alter-
natively.
 Finally rotate the sprocket of the camshaft sprocket (INT) counterclockwise [the direction shown by the
arrow ( )].
 Perform the work while applying the air pressure to the oil hole.
