INSPECTION AFTER REMOVAL

Timing Chain

Check timing chain for cracks and any excessive wear at the roller links of timing chain. Replace timing chain if necessary.

Balancer Unit Bolt Outer Diameter

Measure outer diameters (D, C) at the two positions as shown.
A : 30 mm (1.18 in)
B : 40 mm (1.57 in)
E : 10 mm (0.39 in)
Measure (C) within the range (B).
If the value difference [(D) - (C)] exceeds the limit, replace the balancer unit bolt with a new one.
Limit : 0.15 mm (0. 0059 in) or more

INSPECTION AFTER INSTALLATION

Inspection for Leaks

The following are procedures for checking fluids leak, lubricates 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 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 check 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.
