Tighten further by 90 degrees. (Angle tightening)
●
Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to check for inter-
ference among parts.
16. Install in the reverse order of removal.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
●
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-10, "RECOMMENDED 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
leakage 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.
●
Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids includ-
ing 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
specified level, if necessary.
