7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank- shaft key and the two flat surfaces of oil pump inner rotor.

If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi- tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.

Apply new engine oil to both oil seal lip and dust seal lip.

Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.

Using front oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.

Make sure the garter spring is in position and seal lips not
inverted.

f. Further tighten by 90 degrees. (Angle tightening)

Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after this step. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate 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
Inspection for Leaks
The followings 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-12, "
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.

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.

Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER

Measure the outer diameter of camshaft journal with microme-
ter.
CAMSHAFT BRACKET INNER DIAMETER

Tighten camshaft bracket bolt with the specified torque. Refer to EM-216, "INSTALLATION" for the tight-
ening procedure.

4. Crank the engine, and then make sure that engine oil comes out
from intake valve timing control cover oil hole. End crank after
checking.
WARNING:
Be careful not to touch rotating parts (drive belt, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from intake valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from intake valve timing control cover oil hole. Refer to LU-23, "
LUBRICATION SYSTEM" .
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.

Clean oil groove if necessary. Refer to LU-23, "LUBRICATION SYSTEM" .
6. After inspection, install removed parts.

INSPECTION
In cases of removing/installing or replacing camshaft and valve-related parts, or of unusual engine conditions
due to changes in valve clearance (found malfunctions during starting, idling or causing noise), perform
inspection as follows:
1. Remove rocker covers (right and left bank). Refer to EM-197, "
ROCKER COVER" .
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley in clockwise to align TDC identifica-
tion notch (without paint mark) with timing indicator on front
cover.

Make sure that both intake and exhaust cam noses of No. 1
cylinder (engine front side of left bank) are located as shown
in the figure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

3. For the measured value are out of the standard, perform adjustment. Refer to EM-222, "ADJUSTMENT" .
ADJUSTMENT
NOTE:
Adjust valve clearance while engine is cold.
1. Thoroughly wipe off engine oil around adjusting shim using rag.
2. Rotate crankshaft to position cam nose on camshaft of valve that must be adjusted upward.
3. Using small screwdriver, turn the round hole of adjusting shim in the direction of the arrow.
CAUTION:
perform (the above procedure) during camshaft do not con-
tact with adjusting shim.
4. Install lifter stopper [SST: 10115120 (J38972-2)] as follows:
a. Except exhaust side of No. 7 and 8 cylinder;
i. Place camshaft pliers (SST) around camshaft as shown in the figure.
ii. Rotate camshaft pliers so that valve lifter is pushed down. CAUTION:
Be careful not to damage cam surface, valve lifter and cylin-
der head with camshaft pliers.
iii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter.
CAUTION:

Lifter stopper must be placed as close to camshaft
bracket as possible.

Be careful not to damage cam surface, valve lifter and
cylinder head with lifter stopper.
iv. Remove camshaft pliers. CAUTION:
Camshaft pliers should be removed by rotating it slowly
because lifter stopper hits and damages journal portion by
rotating camshaft pliers quickly.
b. Exhaust side of No. 7 and 8 cylinder; NOTE:
Exhaust side of No. 7 and 8 cylinder does not have space for installing camshaft pliers [SST: KV10115110
(J38972-1)]. therefore, install lifter stopper [SST: KV10115120 (J38972-2)] according to the following
instructions.
i. Rotate crankshaft to press cam nose to the adjusting part of valve lifter.
ii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter. CAUTION:

Lifter stopper must be placed as close to camshaft bracket as possible.

Be careful not to damage cam surface, valve lifter and cylinder head with lifter stopper.
iii. Rotate crankshaft slowly 180 degrees clockwise.
