Installation Notice

Piston Pin Installation

(1) Measure the following sizes of piston, piston

pin and connecting rod.

A：Length of inserting piston pin in the hole.
B：Width of pin sockets
C：Length of piston pin
D：Width of small end of connecting rod.

(2) Put measured sizes above into following formula

to calculate L.

L＝[(A－C)－(B－D)] / 2

(3) After inserting compression rod of the special

tool into piston pin, install pipe A in the top of

compression rod.

(4) Install forward marks of piston and connecting

rod towards the same direction.

(5)

Daub engine oil on the external diameter of

piston pin

(6)

Through Pipe A, insert compression rod,

piston pin and pipe component installed

according to (3) into piston pin hole from the

side of forward mark.

(7)

Screw on guide block B into guide pipe A to

make clearance value between guide block A

and guide block B equal to the value of Value L

got from (3) plus 3mm.

(8) Keep forward mark of piston upward. Install

piston and connecting rod component in base

of piston pin installer.

(9) Force piston Pin in under pressure. When

the pressure is less than standard value,

replace piston pin and piston component

and/or replace connecting rod.

(2) Put upper blade. When installing blade, force

one side of blade into piston oil ring groove.
Then force the rest parts of blade into oil ring
groove with the thumb as shown.
Expanding blade with ring clamp will break it
off and make it differed from other piston
rings.
Caution：
Don’t use ring clamp to install blade

(3) Install lower blade in accordance with Step

(2).

(4) Ensure if blade can turn from the left to the

right freely after installing blade.

Installation of No.1 compression ring and
No.2compression ring
(1) After installing No.2 compression ring, install

No.1compression ring with ring clamp.
Remarks:
1.There’s the identification mark on the top of
the ring.

Identification mark
No.1 ring. 1R
No.2 ring. 2R

2.When installing piston ring, keep the mark
upwards and towards the top of piston.
