STEPS Draining oil-1
PROCEDURE:
●Drain oil
Place a larger container under the engine, use 14 sleeve + ratchet wrench to remove the 2 oil drain bolts at the
bracket and the left crankcase (1), and remove the gasket (2).
Unscrew the oil dipstick (3) on the right crankcase cover, take out the sealing ring (4), and wait for the oil to
drain from the oil drain.
CAUTION：
●Combined gasket ⑵It is recommended to replace it after disassembly to avoid oil leakage and oil leakage due
to damage caused during disassembly.
●After removing the oil drain bolt ⑴, check whether the magnet on the bolt has adsorbed iron filings. If there
are many foreign objects or parts adsorbed, check the inside of the engine. If there is only a small amount of
metal chips, don't worry, just clean it up.
●Draining oil and antifreeze can only be done when the machine is cold to prevent burns.

PROCEDURE:
●Put antifreeze
Place a container under the drain hole, ready to receive antifreeze, use an 8# sleeve to remove the bolt (1), and
remove the copper pad (2).
Locate the water filler cap at the lower link plate on the right side of the vehicle, press down the water filler cap
and turn it counterclockwise before removing it, and wait for the antifreeze to drain.
CAUTION:
●Gasket ⑵After disassembly, new gaskets must be replaced to avoid water leakage.
●Antifreeze is corrosive to a certain extent, so be careful not to contaminate the engine, other parts, body,
clothing, etc., when discharging the antifreeze. If parts are accidentally contaminated with antifreeze,
immediately wipe them with a clean lint-free cloth. If clothing or skin is stained with antifreeze, immediately
rinse with clean water. If the antifreeze is splashed into the eyes, immediately rinse with plenty of water and
observe to decide whether to seek medical attention.
●The engine can be removed from the vehicle after draining the antifreeze and engine oil.

PROCEDURE:
●Cylinder head cover assembly
Use an 8# sleeve to remove 2 bolts ⑴ and 8 bolts ⑵, and remove 1 bolt ⑶ for 6# inner hexagon, then the
cylinder head cover assembly can be removed.
Take out the gasket ⑷, remove one large positioning pin ⑺ and two small positioning pins ⑸. Note: One of
the small positioning pins ⑸ has an O-ring ⑹. Clean up the remaining sealant on the joint surface.
Remove the bolt ⑻ with an 8# sleeve, and remove the copper pad ⑼.
Remove the chain guard ⑽ from the inside of the cylinder head cover ⑽, and install the chain guard ⑽ on the
boss shown in the circle in the figure.
CAUTION：
●
When installing a new gasket, apply a proper amount of sealant on the assembly plane of the cylinder head and
the upper surface of the gasket.
●The cylinder head cover bolts must be evenly loosened or tightened diagonally when removing and installing.
●Gasket ⑷ is for one-time use, and must be replaced after disassembly, otherwise the seal will not be in place
and problems such as engine oil leakage will occur.
●When cleaning residual sealant and other impurities, avoid foreign matter from entering the engine.
