c. Install valve timing control cover with new gasket 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”.
d. 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.

After all bolt are tightened, tighten No.1 bolt to the specified torque again.
8. Install crankshaft pulley as follows:
a. Fix crankshaft using 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 paint mark (A) on crankshaft pulley (2) aligning with the
angle mark (C) on crankshaft pulley bolt (1). Tighten the bolt 90
degrees (one marks) (b).
9. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
10. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid 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-11, "

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 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.

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-11, "
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.
