REAR TIMING CHAIN CASE

g. After installing rear timing chain case, check the surface height

difference between following parts on oil pan (upper) mounting

surface.

• If not within the standard, repeat the installation procedure.

EM-61, "Removal and Installation"

 and 

EM-70,

"Removal and Installation (Secondary Timing Chain Tensioner)"

.

4. Install front timing chain case. Refer to 

EM-53, "Removal and Installation"

.

5. Install oil pan (upper) and (lower). Refer to 

EM-36, "Removal and Installation"

INSPECTION AFTER INSTALLATION

• 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-18, "FOR USA AND CANADA : Fluids and Lubricants"

 (United

States and Canada) and 

MA-20, "FOR MEXICO : Fluids and Lubricants"

 (Mexico).

• 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 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 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.

Standard

Rear timing chain case to lower cylinder block:

–0.24 to 0.14 mm (–0.0094 to 0.0055 in)
