FRONT TIMING CHAIN CASEPFP:13599
Removal and InstallationABS004X0
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 (upper and lower) first. Then remove front timing chain case, timing chain
related parts, and rear timing chain case in this order, and install in reverse order of removal. Refer to EM-
63, "TIMING CHAIN" .

Refer to EM-63, "TIMING CHAIN" for component parts location.
REMOVAL
1. Place vehicle onto lift.
2. Disconnect negative battery terminal.
3. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
4. Remove air cleaner case assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
5. Remove front and rear engine undercover with power tool.
6. Drain engine coolant from radiator. Refer to CO-11, "
Changing Engine Coolant" .
7. Drain engine oil from oil pan. Refer to LU-9, "

8. Remove engine harnesses.
9. Remove intake manifold collectors (upper and lower) with power tool. Refer to EM-19, "
INTAKE MANI-
FOLD COLLECTOR" .
10. Remove power steering oil pump from bracket with piping connected, and temporarily secure it aside.
Refer to PS-31, "
POWER STEERING OIL PUMP" .
11. Remove power steering oil pump bracket. Refer to PS-31, "
POWER STEERING OIL PUMP" .
12. Remove alternator. Refer to SC-23, "
CHARGING SYSTEM" .
13. Remove water bypass hose, water hose clamp and idler pulley bracket and alternator and power steering
oil pump and A/C compressor belt tensioner from front timing chain case.
14. Remove right and left intake valve timing control covers with
power tool.

Loosen bolts in reverse order as shown in the figure.

tool to cut liquid gasket for removal.
CAUTION:
Shaft is internally jointed with intake camshaft sprocket
center hole. When removing, keep it horizontal until it is
completely disconnected.
15. Remove collared O-rings from front timing chain case (left and
right side).

17. Obtain compression TDC of No. 1 cylinder as follows:
NOTE:
When timing chain is not removed/installed, this step is not required.
a. Rotate crankshaft pulley clockwise to align timing mark (grooved
line without color) with timing indicator.
b. Make sure intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360°) and align as
shown.
NOTE:
When only primary timing chain is removed, rocker cover
does not need to be removed. To confirm that No. 1 cylinder is
at its compression TDC, remove front timing chain case first.
Then check mating marks on camshaft sprockets. Refer to
EM-63, "
TIMING CHAIN" .
18. Remove crankshaft pulley with the following procedure:
a. Remove rear cover plate (2WD) or starter motor (AWD) and set
ring gear stopper (SST) as shown in the figure. Refer to SC-10,
"STARTING SYSTEM" .
b. Loosen crankshaft pulley bolt and locate bolt seating surface as
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.
