The front end cover is made of molten horniness

aluminum metal. Oil pump and cleaner system are

located on the front end cover’s board. The cover

board itself is front housing of oil pump.

Front crank oil seal, oil pump seal and

upper balance axle oil seal are pressed

and fixed on front cover board.

The cylinder front end is combined as

horizontal oil pipe and there is an oil

pipe to lubricate the rear bearing of

lower balance axle.

Both upper and lower balance axles are

supported by front end cover board.

Lower balance axle is also driven axle

of oil pump.

Crankshaft is made of forged carbon

steel, which surface is machining

processed

The location of crankshaft oil pipe is as

shown.

Crankshaft is full-balance type, that is

Balance Number = Number of

Cylinders × 2.

The rotary radius of crankshaft main

axle center and crankshaft pin center is

separately 88/2（4G63）

，100/2（4G64）.

Main axle diameter/57mm、Connecting

rod diameter/45mm（The diameter of

4G63 and 64 is same）

；

The rear end flange is thickened as oil

seal top and don’t impact it. Seven

flywheel bolts are part distributed and

there is a flywheel locking pin.

It is made of molten horniness

aluminum, which has been surface

processed.

There is a roundness concave on the top,

which makes chamber compacted,

decreases F/V value, reduces

nocuousness emission, increases power

and decreases oil consumption. There is

valve pit on the right side of piston,

which makes chamber structure more

impacted.

There are two air ring slots and one oil

ring slot. A oil return hole is drilled in

the oil ring slot, which lubricate piston

pin mating and reduce dynamic

pressure of oil ring.

There is oil slot in the inside upper of

piston pin seating, which collect splash

oil to lubricate piston pin mating
