Selection of Connecting Rod Bearing Shell

1. Selection of connecting rod bearing upper shell.

Connecting rod bearing upper shells are divided into red
shells and blue shells. Related marks are available on
the connecting rod. Select related connecting rod bearing
shell according to the marks.
As shown in the illustration, among the mark "130523 B"
on the connecting rod, "B" indicates blue shell.

2. Selection of connecting rod bearing lower shell.

Related digital marks are available on the first balancer at
the front end of crankshaft (consisting of "1" and "2").
Such as "1221" on the first crankshaft front end balancer
shown in the illustration, the first digit "1" is for the lower
shell type of the 1st cylinder piston connecting rod, and
so on; the fourth digit "1" is for the lower shell type of the
fourth cylinder piston connecting rod.

3. Precautions for connecting rod bearing shell assembly:

a. The connecting rod upper and lower bearing shells without oil grooves are universal, but one of the

connecting rod bearing shells has oil hole.

b. It is necessary to use a set of connecting rod bearing shells that are provided by the same

manufacturer on the same engine.

c. Apply a coat of engine oil to the inner surface of the connecting rod bearing shell before installation.

The back side of bearing shell should be clean without any oil or foreign matter during assembly.

Assembly

1. Install the crankshaft main bearing shell.

CAUTION

 Apply a coat of engine oil to the inner surface of main bearing shell before installation.

07–

a. Carefully install the crankshaft bearing uppe shell (1)

in the direction of arrow, and the notch of each main
bearing upper shell should be aligned with the
cylinder block. The oil passage hole (2) on crankshaft
main bearing should be aligned with the passage hole
on cylinder block after installation.

HINT:
Install the crankshaft main bearing lower shells to the
crankshaft frame in the same way,and the notch of
each main bearing lower shell should be aligned with
the crankshaft frame.

2. Install the crankshaft thrust washer.

a. Clean the crankshaft thrust washers and cylinder block inner wall before installation.
b. Apply a coat of engine oil to the crankshaft thrust washers.
c. There are 2 crankshaft thrust washers on the cylinder, which are installed on the front and rear sides of

thrust surface (both sides of 3rd bearing) respectively.

d. As shown in the illustration, the two grooves on one

side of crankshaft thrust washers (1) face outward
while the other side without groove is jointed with the
cylinder block inside wall.

3. Install the crankshaft.

a. Apply seal gum to the installation surface of frame

before installation.

b. Place the crankshaft on the cylinder block carefully.
c. Install the crankshaft main bearing cap fixing bolts in

place by hand, and tighten 10 crankshaft main
bearing cap fixing bolts in the order shown in the
illustration.



(Tightening torque: 1st step: tighten to 45 ± 5 N·m;
2nd step: retighten for 180° ± 10°)

d. Evenly tighten 10 crankshaft frame fixing bolts in the

order shown in the illustration.



(Tightening torque: 20 + 3 N·m)

4. Install the piston ring.

a. The first compression ring is rectangular ring (1), the

second compression ring is conical ring (2), and the
oil ring is steel band combination ring. Apply a small
amount of engine lubricant to the piston ring groove
and piston. Note that the side with words for first
compression ring should face upward and the outer
cutting of second compression ring should face
downward.

b. The oil ring is steel band combination oil ring and

composed of upper rail (3), lower rail (5) and
expander (4). When installing the oil ring, first install
the expander into the oil groove, then install the two
rails with the two rails opening of steel band
combination oil ring staggered by 90° from the
expander closed gap, and the upper and lower rails
180°. Then install the second compression ring, and
install the first compression ring finally with the two
compression rings staggered by 120° from the upper
rail opening. The piston ring should rotate in the ring
groove freely without any stuck condition.

CAUTION

 DO NOT apply seal gum into the bearing shell installation area when applying seal gum.
 Seal gum should not be applied too thick. Avoid seal gum entering bearing shell installation area due to

compressing.

c. Rotate the piston ring several turns after applying engine oil to the piston ring groove, and note that the

position of ring notch should be the same with that described above; clean the crankshaft connecting
rod journal and cylinder bore with a non-woven fabric cloth.

5. Install the connecting rod bearing shell.

a. Carefully install the connecting rod bearing upper

shell (1) in the direction of arrow, and keep the groove
opening of each connecting rod bearing upper shell
face the piston and connecting rod assembly.

b. Carefully install the connecting rod bearing lower shell

(1) in the direction of arrow, and keep the groove
opening of each connecting rod bearing lower shell
face the connecting rod bearing cap.

6. Install the piston connecting rod assembly.

a. Rotate the crankshaft to the top dead center of 1st and 4th cylinder.
b. Apply a coat of engine oil to the piston surface and cylinder inside wall.
c. As shown in the illustration, install the piston

connecting rod assembly to the cylinder with the
piston installer (1).

CAUTION

 Apply a coat of engine oil to the inner surface of connecting rod bearing shell before installation.
 Back side of connecting rod bearing shell should be clean without any oil or foreign matter during

assembly.
