External gear oil pump is applied

and its oil supply performance is

better than current rotor pump. The

efficiency of external gear pump is

high, that is, the efficiency of

oil supply is proportional to the

speed,

which

may

satisfy

large-load oil supply requirement.

However, if rotor pump speed

increase, the oil pump efficiency

will increase at low speed, but it

will drop gradually when the speed

reach mid-speed as shown, which

will cause lack of large-load oil

supply. Therefore, large load

should be considered when designing rotor

pump, but it will consume power during low

loading.

1 Disassembling Notice



Disassembling of timing belt

Remember the rotation direction of belt in order to
avoid any error when reassembling.

Caution:

1) If there is water or grease on the belt, the

lifecycle of belt will be decreased rapidly.
So, after disassembling, take care not to
have water or grease adhere to and pollute
the belt, the pulley, and the tensioner. Do
not clean these parts. When they are
seriously polluted, please replace them with
new ones.

2)If water or grease is found in these parts,

please check whether there is any leakage in the
oil seal of front cover, the oil seal of camshaft and
water pump.



Disassembling of oil pump pulley

(1) Disassemble the plug cock on the cylinder side.

(2)

Insert

an 8mm-diameter cross-ended

screwdriver to fasten the left side balance shaft.

(3)

Disassemble the screw nut of oil pump pulley.

(4)

Disassemble the oil pump pulley.



Disassembling of crankshaft screw
bolt (Disassembling of flywheel)

(1)

Fix the driving board or flywheel with special

tool.

(2) Disassemble the crankshaft screw bolt. Support

the driving board or flywheel with special tool.



Disassembling of crankshaft pulley

If it is difficult to disassemble due to the reason of
adhering, please apply special tool.



Disassembling of timing belt B

(1)Remember the rotation direction of belt to

avoid any error when reassembling.

Notice:

If there is water or grease on the belt, the lifecycle of
belt will be decreased rapidly. So, after
disassembling, take care not to have water or grease
adhere to and pollute the belt, the pulley, and the
tensioner. Do not clean these parts. When they are
seriously polluted, please replace them with new
ones.
