Removal and InstallationBBS004VZ
NOTE:

This section describes removal/installation procedure of front timing chain case and timing chain related
parts without removing oil pan (upper) on vehicle.

When oil pan (upper) needs to be removed or installed, or when rear timing chain case is removed or
installed, remove oil pans (lower and upper) first. Then remove front timing chain case, timing chain
related parts, and rear timing chain case in this order, and install in the reverse order of removal. Refer to
EM-173, "
TIMING CHAIN" .

Refer to EM-173, "TIMING CHAIN" for component parts location.
REMOVAL

(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
NOTE:
When only timing chain (primary) is removed, rocker cover does
not need to be removed. To make sure that No. 1 cylinder is at
its compression TDC, remove front timing chain case first. Then

16. Remove crankshaft pulley as follows:
a. Fix crankshaft with pulley holder (SST).
b. Loosen crankshaft pulley bolt and locate bolt seating surface at
10 mm (0.39 in) from its original position.
CAUTION:
Do not remove crankshaft pulley bolt as it will be used as a
supporting point for suitable puller.
c. Place suitable puller tab on holes of crankshaft pulley, and pull
crankshaft pulley through.
CAUTION:
Do not put suitable puller tab on crankshaft pulley periph-
ery, as this will damage internal damper.
17. Remove oil pan (lower). Refer to EM-145, "
OIL PAN AND OIL STRAINER" .
18. Loosen two mounting bolts in front of oil pan (upper) in the
reverse order as shown in the figure.

smoothly.
13. For the following operations, perform steps in the reverse order of removal.
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-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

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.
