INSTALLATION
1. With box wrench, and while securely holding the hexagonal part
in center of drive belt auto-tensioner pulley, move the wrench
handle in the direction of arrow (loosening direction of ten-
sioner).
CAUTION:

Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.

Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
2. Insert a rod approximately 6 mm (0.24 in) in diameter such as short-length screwdriver into the hole of
retaining boss to fix drive belt auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump, and then onto water pump pulley finally.
CAUTION:

Confirm belt is completely set to pulleys.

Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-14, "
Checking Drive Belts" .

(Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)

If out of the standard, replace either or both camshaft and cylinder head.
NOTE:
Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play

–Dimension “B” for cylinder head No. 1 journal bearing

Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.
2. Measure the camshaft sprocket runout with dial indicator. (Total
indicator reading)

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-5, "
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-5, "LUBRICATION SYSTEM" .
6. After inspection, install removed parts.
Valve ClearanceBBS00596
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-39, "
ROCKER COVER" .
2. Open splash guard on RH undercover.
3. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley clockwise and align TDC mark to
timing indicator on front cover.

At the same time, make sure that both intake and exhaust
cam noses of No. 1 cylinder face outside as shown in the fig-
ure.

If they do not face outside, rotate crankshaft pulley once more
(360 degrees) and align as shown in the figure.
