(2) For the BOSCH or XINFENG fuel injector: Remove
the dust cap from the upper end of the fuel injector.
Install the 4 short connectors of the fuel return hose in
the 4 holes at the upper end of the fuel injector, and fix
them tightly with clamping springs. Install the other long
connector to the fuel return tee on the high pressure
pump, and fix it tightly with a small steel belt spring clip.
Make sure the fuel return hose is sealed properly
without leakage after the installation.
(10) Reinstall the fuel inlet pipes of fuel injector and the
fuel inlet pipe component of fuel rail.
——Install the fuel inlet pipes of fuel injector and evenly
tighten the connectors at both ends of the 4 fuel inlet
pipes of fuel injector as per the specified torque. See
Fig. 4-5-39.
——Install the fuel inlet pipe component of fuel rail and
tighten the connectors at both ends of the fuel inlet pipe
component of fuel rail as per the specified torque.
Make sure the fuel pipe is sealed without oil
leakage after the installation.

Attention:
During the installation, make sure the
connectors at both ends of the fuel inlet pipe of fuel
injector and the fuel inlet pipe component of fuel rail are
evenly tightened at the same time. Otherwise, the fuel
pipe may be distorted.

(1) Install the woodruff key to the exhaust camshaft,
install the timing pulley to the exhaust camshaft and
tighten the fastening bolt washer component as per the
specified torque. The camshaft timing pulley should be
pressed and installed to the right position without
deflection.
(2) Adjust the scale mark on the camshaft timing pulley
to align it with the bone-line (at exhaust side) between
the cylinder head and the camshaft bearing cap. See
Fig. 4-5-40.
