b. Push in chain tensioner plunger. Insert a stopper pin into hole on
chain tensioner body to secure chain tensioner plunger and
remove chain tensioner.
NOTE:
Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a
stopper pin.
c. Secure hexagonal part of camshaft with a wrench. Loosen cam-
shaft sprocket mounting bolts and remove camshaft sprockets.
CAUTION:
Do not rotate crankshaft or camshaft while timing chain is
removed. It causes interference between valve and piston.
NOTE:
Chain tension holding work is not necessary. Crankshaft
sprocket and timing chain do not disconnect structurally while
front cover is attached.
8. Remove camshaft position sensor (PHASE) from cylinder head back side.
CAUTION:

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 sensor in a location where it is exposed to magnetism.
9. Loosen mounting bolts in reverse order as shown in the figure,
and remove camshaft brackets and camshafts.

Remove camshaft bracket (No. 1) by slightly tapping it with a
plastic hammer.
10. Remove valve lifters.

Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)

A widely use engine stand can be used.
NOTE:
This example is an engine stand for holding at transaxle
mounting side with flywheel (M/T models) or drive plate (A/T
models) removed.
3. Drain engine oil. Refer to LU-8, "
Changing Engine Oil" .
4. Drain engine coolant by removing water drain plug from inside of
engine.
5. Remove cylinder head. Refer to EM-70, "
CYLINDER HEAD" .
6. Remove knock sensor.
CAUTION:
Carefully handle knock sensor avoiding shocks.
7. Remove crankshaft position sensor (POS).
CAUTION:

Avoid impacts such as a dropping.

Do not disassemble.

Keep it away from metal particles.

Do not place sensor in a location where it is exposed to
magnetism.
8. Remove clutch cover and clutch disc (M/T models). Refer to CL-16, "
CLUTCH DISC, CLUTCH COVER
AND FLYWHEEL" .
9. Remove flywheel (M/T models) or drive plate (A/T models).

Secure crankshaft with a stopper plate, and remove mounting
bolts.

Using the following TORX socket, loosen mounting bolts.
CAUTION:
Be careful not to damage contact surface for clutch disc of
flywheel (M/T models).

Install drive plate, reinforcement plate and pilot converter as
shown in figure (A/T models).

Using a drift of 33 mm (1.30 in) in diameter, press-fit pilot con-
verter into the end of crankshaft until it stops (A/T models).
14. Install knock sensor.

Install knock sensor with connector facing lower left by 45
degrees as shown in the figure.
CAUTION:

Do not tighten mounting bolts while holding the connec-
tor.

If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.

Make sure that knock sensor does not interfere with other
parts.
15. Install crankshaft position sensor (POS).
16. Assemble in the reverse order of disassembly after this step.
How to Select Piston and Bearing EBS00KNV
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only grade “0” is available.) The
information at the shipment from the plant is described as a reference.

The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.

For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.

For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
