2008 GEELY FC Workshop Manual

Engine mechanism - Camshaft(h) Hold timing chain with hands and then remove intake
camshaft.
(i) As shown in the diagram, tie up the chain with bandage.
Note: be careful not to let anything fall into the timing
chain hood.10. Check VVT driver assembly [4G18-1006300].(a) Check locking state of timing sprocket.
Clip the camshaft with a jaw vice, and ensure VVT driver
is locked tightly.
Note: be careful not to damage intake camshaft.
(b) Release lock pin.
(1) As shown in the diagram, seal 5 oil ducts of intake
camshaft journal with vinyl rubber cloth.
Hint: there are 2 advance side oil ducts in the groove
of intake camshaft, and clog one of them with
rubber block.
(2) In opposite side of the groove, prick a hole on
vinyl rubber cloth of advance side oil duct surface
and delay side oil duct surface.
(3) Send in 2 oil ducts (advance side oil duct and
delay side oil duct) with the surface rubber cloth
pricked under the pressure of 150Kpa.
Warning: cover the oil ducts with cloth to avoid
oil injecting out in pushing.54Delay side

Engine mechanism - Camshaft(4) Ensure whether the timing sprocket of VVT driver
will turn toward timing advance direction in de-
creasing the pressure of timing delay oil duct.
(5) When camshaft timing sprocket turns at max.
timing advance position, release the air pressure
in timing delay side oil duct, and then release the
air in timing advance side oil duct.
Hint: camshaft timing sprocket will turn only af-
ter the lock pin is released.
(d) Check the fixing state of max. delay position.
Ensure camshaft timing sprocket assembly is fixed at
max. delay position.11. Remove VVT driver assembly.(a) Clip the camshaft with a jaw vice, and ensure VVT driver
is locked tightly.
Warning: be careful not to damage camshaft.
(b) As shown in the diagram, seal 5 oil ducts of camshaft
journal with vinyl rubber cloth.
Hint: there are 2 advance side oil ducts in the
groove of camshaft, and clog one of them
with rubber block.
(c) In opposite side of the groove, respectively prick a hole
on vinyl rubber cloth of advance side oil duct surface
and delay side oil duct surface.
(d) Send in 2 oil ducts (advance side oil duct and delay
side oil duct) with the surface rubber cloth pricked
under the pressure of 150Kpa.
Warning:cover the oil ducts with cloth to avoid
oil injecting out in pushing.
(e) Ensure whether the timing sprocket of VVT driver will
turn toward timing advance direction in decreasing the
pressure of timing delay oil duct.
Hint: camshaft timing sprocket will turn toward
advance direction only after the lock pin is
released.
(f) When camshaft timing sprocket turns at max. timing
advance position, release the air pressure in timing
delay side oil duct, and then release the air in timing
advance side oil duct. Warning: if the air pressure in timing advance side oil duct is released earlier than that
in timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side, and the lock pin will be damaged.
(c) Check rotating is smooth.
Besides max. delay position, turn VVT driver assembly within rotating rang and check rotating is
smooth.
Warning: Perform inspection with hands but not with
compressed air.55Delay side

Engine mechanism - CamshaftWarning: if the air pressure in timing advance side oil duct is released earlier than that in
timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side.This will cause the damage of lock pin.
(g) Remove VVT drive fixed bolts.
Notes:
It is strictly forbidden to remove other 4 bolts.
Under the condition of repeating using camshaft
timing sprocket, release lock pin at first, and then
install sprocket.12. Install VVT driver assembly.
13. Install camshaft.Put VVT driver assembly together with intake camshaft.
(a) As shown in the diagram, gently make VVT assembly
hold camshaft and turn it toward left until straight pin is
inserted into groove.
Warning: it is strictly forbidden to turn camshaft
timing sprocket toward timing delay side
(toward right).
(b) Check there is no clearance between sprocket flange
and camshaft.
(c) Fix camshaft timing sprocket and then tighten flange
bolt.
Torque: 70 ±5N.m
(d) Check VVT driver assembly could move to timing
delay side and is locked at max. timing delay position.
(f) As shown in the diagram, align alignment mark with
timing mark on camshaft timing sprocket, and install
timing chain on the timing sprocket.
(g) Check forward mark and figure, and tighten bolts as
sequences shown in the diagram.
Torque: 13 ±0.78N.m
(h) Align alignment mark on the chain with timing mark on
camshaft timing sprocket, and place exhaust camshaft
in cylinder head.Straight pin

Engine mechanism - Camshaft(i) Temporarily tighten fixed bolts.
(j) Check forward mark and figure, and tighten bolts as
sequences shown in the diagram.
Torque: ±0.78N.m
(k) Install camshaft front bearing cover.
Torque: 23 ±1.38N.m
(l) Fix camshaft with variable wrench and then tighten the
fixed bolts of exhaust camshaft timing sprocket.
Torque: 54 ±10.8N.m
Note: be careful not to damage valve lifter.
(m)Check the alignment marks on timing chain and cam-
shaft timing sprocket, and then align the groove of damp-
ing pulley with the timing mark on timing chain hood as
shown in the diagram.Fixing

Engine mechanism - Camshaft(n) Install chain tensioner components.
(1) Check o-ring is clean, and buckle on the hook as
shown in the diagram.
(2) Coat engine oil on the chain tensioner, and then
install it.
Torque: 9 ±1.8N.m
Note:when installing the chain temsioner,
buckle on the hook again if plunger has
ejected.
(3) Turn crankshaft counterclockwise to separate the
hook from lock pin on the plunger.
(4) Turn crankshaft clockwise, and check the sliding
parts are blocked by plunger.
Hint: if the plunger does not eject, press the ten-
sion rail toward chain tensioner with
screwdriver or fingers to separate the hook
from lock pin and make the plunger eject.Pushing into
