a.

Install new seal rings in shaft grooves.

b.

Install magnet retarder aligning the dowel pins of the back with
the cover side dowel pin holes securely. Simultaneously insert
the harness into the installation groove securely.
NOTE:
Figure shows the structure of the parts. Therefore, magnet
retarder is being removed from the cover in this figure. But, if
magnet retarder is in the correct position, omit step “b” and per-
form step “c”.

c.

To check the joint between dowel pins and dowel pin holes,
check the looseness in the axle direction by pushing the mating
surface of magnet retarder at several places and the circumfer-
ential looseness (between dowel pins and dowel pin holes) by
twisting in the circumferential direction.

CAUTION:

Always perform this procedure when removing because the
gap between dowel pins and dowel pin holes may not be
caused on purpose.

d.

Install valve timing control cover to front timing chain case.

CAUTION:

●

Do not face the magnet retarder side down to prevent
magnet retarder from dropping.

●

Check the mating surface of magnet retarder and the
drum of exhaust side camshaft sprocket for foreign mate-
rials.

●

Align the center of both shaft holes of the shaft and the
intake side camshaft sprocket, and then insert them.

●

Be careful not to drop the seal ring from the shaft groove.

●

When setting the valve timing control cover in position
by hand, if valve timing control cover is not contacting with the front timing chain case, the
dowel pin of magnet retarder may not be aligned with the dowel pin holes of cover. In this case,
return to step “b”.

e.

Tighten mounting bolts in numerical order as shown in the fig-
ure.

CAUTION:

Completely tighten the mounting bolts with the seat surface
of valve timing control cover contacting with front timing
chain case.

16. Install oil pans (upper and lower). Refer to 

EM-29, "OIL PAN AND OIL STRAINER"

 .

17. Install rocker covers (right and left banks). Refer to 

EM-44, "ROCKER COVER"

 .

18. Install crankshaft pulley as follows:
a.

Fix crankshaft using ring gear stopper [SST: KV10117700 (J44716)].

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 (1) aligning with
the matching (B) of crankshaft pulley bolt (2). Tighten the bolt 90
degrees (one marks).

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

smoothly.

20. Install in the reverse order of removal after this step.

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.

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/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 gases, 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.
