• Fuel tube and fuel injector assembly. Refer to
EM-152.
• Front cover, timing chain and related parts. Refer to EM-156
.
• Generator. Refer to SC-25, "
Removal and Installation".
7. Remove camshaft position sensor (PHASE) from camshaft bracket. CAUTION:
• Handle carefully to avoid dropping and shocks.
• Never disassemble.
• Never allow metal powder to adhere to magnetic part at sensor tip.
• Never place sensor in a location wher e it is exposed to magnetism.
8. Put matching marks (A) on the camshaft sprocket (INT) (2) and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2). • Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
• Never rotate crankshaft or camshaft while timing chainis removed. It causes interference between valve and
piston.
• Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then remove the camshaft bracket.
CAUTION:
• Be careful not to damage the mating surface.
• A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
the position not specified.

• Measure the inner diameter of camshaft bracket with a bore gauge
(A).
CAMSHAFT JOURNAL OIL CLEARANCE
• (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
• If it exceeds the limit, replace camshaft or cylinder head, or both. NOTE:
Camshaft bracket cannot be replaced as a single part , because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head.
2. Install dial indicator in thrust direction on front end of camshaft. Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).
• Measure the following parts if out of the standard.
- Dimension (A) for groove of cylinder head No. 1 journal
- Dimension (B) for camshaft flange
• Apply the standards above, and then replace camshaft and/or
cylinder head, if necessary.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft. CAUTION:
Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.

• Clean camshaft journal to remove any foreign material.
• Distinguish between the intake and the exhaust by looking at
the different shapes of the front and rear ends of the camshaft
or using the identification colors (A) and (B).
• Install camshafts so that camshaft dowel pins (A) on the front side are positioned as shown.
NOTE:
Though camshaft does not stop at t he positions as shown, for
the placement of cam nose, it is generally accepted camshaft
is placed for the same direction as shown.
3. Remove foreign material completely from camshaft bracket backside and from cylinder head installation face.
4. Apply liquid gasket (A) to camshaft bracket as shown. Use Genuine Silicone RTV Seal ant or equivalent. Refer to

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator, and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-191, "
Component".
6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
CAUTION:
• Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engi ne oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid valve oil hole of the cylinder head.
• Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-195, "
Component".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-16
.
8. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-16
.
