b.

Select the one most visible notch of the four on the bolt flange.
Corresponding to the selected notch, put a alignment mark
(such as paint) on the crankshaft pulley. 

14. Rotate the crankshaft pulley in normal direction (clockwise when

viewed from engine front) to check for parts interference.

15. Installation of the remaining components is in the reverse of

order of removal.

INSPECTION AFTER INSTALLATION

• Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are

lower than required quantity, fill to the specified level. Refer to 

MA-12, "Fluids and Lubricants"

.

• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to the fuel piping, check for fuel

leakage at the 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 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 is no leakage of fuel, exhaust gas, or any oil/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to

specified level if necessary.

• Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

INSPECTION AFTER REMOVAL

Camshaft Runout

1.

Put V block on precise flat work bench, and support No. 1 and
No. 5 journals of the camshaft.

2.

Set dial indicator vertically to No. 3 journal.

3.

Turn the camshaft to one direction, and measure the camshaft
runout on dial indicator (total indicator reading).

• If measurement exceeds specification, replace the camshaft.

Camshaft Cam Height

• Measure the camshaft cam height.

• If measurement is not within the specifications, replace the cam-

shaft.

Camshaft Journal Clearance

 Camshaft Journal Diameter

• Measure the diameter of the camshaft journal.

Camshaft Bracket Inner Diameter

NOTE:
The inner diameter of the camshaft bracket is manufactured together with the cylinder head. Replace the
whole cylinder head as an assembly.

Camshaft End Play

• Install dial gauge in the thrust direction on the front end of the cam-

shaft. Measure the end play when the camshaft is moved forward/
backward (in direction to axis).

• If measurement is out of the specified range, replace the camshaft

and measure again.

• If measurement is still out of the specified range, replace the cylin-

der head.

• Measure the following parts if end play is outside the specified

value.

- Dimension 

″

A

″

 for camshaft No. 1 journal

- Dimension 

″

 for cylinder head No. 1 journal

• If measurements are not within specification, replace the camshaft

and/or cylinder head.

Camshaft Sprocket Runout

1.

Install the camshaft in the cylinder head.

2.

Install the camshaft sprocket to the camshaft.

3.

Measure the camshaft sprocket runout.

• If measurement exceeds the specification, replace the cam-

shaft sprocket.

Valve Lifter

Check if the surface of the valve lifter has any wear or cracks.
• If any damage is found, replace the valve lifter.
