Rocker cover; Refer toEM-30, "IGNITION COIL, SPARK PLUG AND ROCKER COVER" .

Fuel tube and fuel injector assembly; Refer to EM-33, "FUEL INJECTOR AND FUEL TUBE" .

Front cover, timing chain and related parts; Refer to EM-37, "TIMING CHAIN" .
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 where it is exposed to magnetism.
8. Put the matching mark (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
previous types when shipped, so it should not be forced
off the position not specified.
