14. Install crankshaft pulley as follows:

a.

Fix crankshaft using the ring gear stopper [SST: KV10118600 (J-48641)].

b.

Install crankshaft pulley, taking care not to damage front oil seal.
• When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).

c.

Tighten crankshaft pulley bolt.

d.

Place a matching mark (A) on crankshaft pulley (2) aligning with
the matching (C) of crankshaft pulley bolt (1). Tighten the bolt 90
degrees (one marks) (b).

e.

Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.

15. For the following operations, perform steps in the reverse order of removal.

INSPECTION AFTER REMOVAL

Timing Chain

Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.

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 

GI-15, "Recommended Chemical Products and Sealants"

.

• 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 chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.

• Warm up engine thoroughly to make sure 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.

Summary of the inspection items:

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