c. Tighten bolts to the specified torque in order as shown in the fig-
ure.
d. After tightening, retighten them to specified torque in numerical
order shown in figure.
20. After installing front timing chain case, check the surface height
difference between the following parts on the oil pan mounting
surface.
If not within specification, repeat the installation procedure.
21. Install right and left intake valve timing control covers as follows:
a. Install seal rings in shaft grooves.
b. Apply liquid gasket to intake valve timing control covers as
shown in the figure with tube presser [SST: WS39930000 ( – )].

c. Install collared O-ring in front cover engine oil hole (left and right
sides).
d. Being careful not to move seal ring from the installation groove,
align dowel pins on chain case with the holes to install intake
valve timing control covers.
e. Tighten bolts in the numerical order as shown in the figure.
22. Install crankshaft pulley as follows:
a. Fix crankshaft using ring gear stopper [SST: KV10117700 (J-44716)].
b. Install crankshaft pulley, taking care not to damage front oil seal.
When press-fitting crankshaft pulley with a plastic hammer, tap on its center portion (not circumfer-
ence).
c. Tighten bolt.
d. Put a paint mark on crankshaft pulley aligning with angle mark
on crankshaft pulley bolt. Then, further retighten bolt by “60”
degrees (equivalent to one graduation).
23. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
24. For the following operations, perform steps in the reverse order of removal.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Before starting engine, check the levels of engine coolant, lubrications and working fluid. If less than
required quantity, fill to the specified level.
Run engine to check for unusual noise and vibration.

Handle carefully to avoid dropping and shocks.
Do not disassemble.
Do not allow metal powder to adhere to magnetic part at
sensor tip.
Do not place sensors in a location where they are
exposed to magnetism.
3. Remove intake valve timing control solenoid valve from No.1
camshaft bracket.
4. Remove intake and exhaust camshaft brackets.
Mark camshafts, camshaft brackets, and bolts so they are
placed in the same position and direction for installation.
Equally loosen camshaft bracket bolts in several steps in the
reverse order as shown in the figure.
5. Remove camshaft.
6. Remove valve lifter.
Identify installation positions, and store them without mixing them up.

Removal Work
1. Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of suspension member and transmission.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
2. Remove rear member mounting bolt.
3. Remove suspension member mounting bolt and nut. Refer to
FSU-6, "
