5.1 ENGINE LUBRICATION SYSTEM
The engine crankshaft drives the pump gears of oil pump.
Pump gears rotate the plunger shaft in oil
pump. This shaft sent the lubricating oil into the crankcase
to mix with the mixture of air-fuel flow evenly.
The oil drops and foam cover the cylinder inner wall,
piston surface and piston rings.
5.2 CAUTION
Having enough oil supply to engine is very important.
If the oil quantity is not enough, this engine will be serious scratched, and then this engine will stop, even
cannot work again.
When this engine is serious scratched, you need to change the piston, piston rings and cylinder together.
Also you need to check the combustion system and lubrication system carefully.
5.3 OIL PUMP
The quantity of oil that deliver out from oil pump increased by the engine speed and the carburetor throttle
open width. Oil pump is under the right side of the engine and connected by a control cable of throttle.
5.4 COOLING SYSTEM
The engine-cooling fan sucks the air.
The cooling fan is on the right side of engine.
The air is forced to flow through cylinder fin and
cylinder head. So, the cylinder and piston will not
over heat.
