18. Install knock sensor (1).
• Install connectors so that they are positioned towards the rearof the engine.
CAUTION:
• Never tighten bolt while holding the connector.
• 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.
19. Install crankshaft position sensor (POS) and cover. • Tighten bolts with it seated completely.
20. For the oil level gauge guide (1), fix the position (B) shown to the water inlet clip (A) after inserting to the cylinder block side.
21. Assembly is in the reverse order of disassembly after this step.

CRANKSHAFT END PLAY • Measure the clearance between thrust bearings and crankshaft arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings, and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE • Measure the side clearance between connecting rod and crank- shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exc eeds the standard, replace crank-
shaft also.

• Rocker cover; Refer to
EM-153 .
• Fuel tube and fuel injector assembly; Refer to EM-156 .
• Front cover, timing chain and related parts; Refer to EM-160 .
7. Remove camshaft position sensor (PHASE) from camshaft bracket. CAUTION:
• Handle carefully to avoid dropping and shocks.
• Never disassemble.
• Never allow metal powder to adhere to magnetic part at sensor tip.
• Never place sensor in a location wher e it is exposed to magnetism.
8. Put matching marks (A) on the camshaft sprocket (INT) (2) and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2). • Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
• Never rotate crankshaft or camshaft while timing chain
is removed. It causes interference between valve and
piston.
• Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then remove the camshaft bracket.
CAUTION:
• Be careful not to damage the mating surface.
• A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
the position not specified.
12. Remove camshafts. : Engine front

2. Install engine to engine stand as follows;
a. Remove flywheel (M/T models) or drive plate (1) (A/T or CVT models).
• Secure flywheel (M/T models) or drive plate (A/T or CVT mod-
els) using Tool (A), and remove bolts.

b. Lift the engine with a hoist to install it onto widely use engine stand. CAUTION:
• Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.
• If the load capacity of stand is not adequate, remo ve the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Exhaust manifold; Refer to EM-144 .
- Rocker cover; Refer to EM-153 .
