Chery Amulet Engine. Manual — part 10

【13】. Engine oiling system:
1). The description of the oiling system:

Through oil collector (2), the rotary oil pump (1) which is
installed in the front end of crankshaft draws oil from oil pan (3)
and pressurizes. The pressure oil comes into the full flow type oil
filter through the assistant oil passage (4) on the left of cylinder
body (viewed from the front). The pressure relief valve (6) is
installed inside the oil pump case to control main oil passage
pressure. The pressure relief valve will be opened under the
pressure within

64 psi ±3 psi. The filtered oil comes out from

the center hole of oil filter and comes into the main oil passage of
engine (5) through the center hole of filter connector.
From the main oil passage, oil lubricates the main bearing
through the bore in the cylinder body and lubricates the
connecting rod bearing through oil passage in the crankshaft.
There is a small oil port in the connecting rod bearing bore
near the exhaust side in the connecting rod body. The oil sprays
out from this small oil port to lubricate the piston pin and cylinder
bore.
Oil pressure sensor (8) is located near the oil filter. It is
connected with the main oil passage by a inner oil passage. Oil is
provided to the third journal of camshaft through this oil passage.
Other journals of camshaft are lubricated by the oil provided
by the middle oil passage of camshaft. Two sides of the middle
oil passage are sealed by steel ball.

Hydraulic lifter oil comes from oil gallery on cylinder head,

which is supplied from oil channel on camshaft neck
The oil provided by the oil port inside the hydraulic valve
lifting rod lubricates the contact face of valve rocker and
hydraulic valve lifting rod.
The oil to lubricate the rocker carrier is provided by the oil
passage of cylinder head.
The contact face of the tip end of valve and rocker is
lubricated by splashing.

2) The removal and installation of oil pan：

Removal：
——Loosen drain plug and drain oil
——Loosen eighteen M6×20 bolts
——Take out the sealing gasket of oil pan
——Check if the left and right reinforced plates are still clipped on the
back face of oil pan flange face

Installation：
——Apply locite 598 sealant
and G Y409 anaerobic sealant
on the joint place between
flange surface of oil pan of
cylinder body and oil pump case,
and carrier of real oil seal.
——Put the new rubber seal
gasket on the cylinder body and
have the two sides of sealing
gasket enter into the grooves of
carrier of real oil seal and oil
pump.

——Install the oil pan with the
two sides of sealing gasket in
the grooves of oil pan.

——Screw the bolt by hand (the bolt with washer indicated in the

left upper figure is precedent.)

——Tighten bolts to 53 in-lbs according to the sequence of the

left figure.

——Replace the sealing gasket of drain plug. Screw in the drain plug

by hand and tighten to

17 ft-lbs.

The removal and installation of oil collector assembly

Removal：
——Loosen locknut of oil collector assembly and take out the nut
and flat washer
——Loosen carrier bolts and take out the bolts。
——Loosen flange face bolt of oil collector (two ) and take out the
two bolts with spring washers

Installation：

——Install a new
sealing gasket of
oil collector on
the flange face of
oil pump and then
install

oil

collector assembly.
Screw two bolts
with gasket by
hand.

——Screw the oil
collector

carrier

into the cylinder
body

with M8

bolt. At the same
time, hitch the
carrier into the
stud which is in
the left of the
second

bearing

cap. Install the
flat washer and
screw in the nut
by hand.

——Tighten the
flange face bolt of
oil collector to

——Tighten carrier bolt to

——Tighten the locknut to
