Fig.2 CRANKCASE

Crankcase Split 2

PROCEDURE:

Cabinet split

   Place the left crankcase horizontally (the closing surface is facing upward), and take out
the right crankcase assembly, gasket 

, and positioning pin 

.

   Press the shift shaft 

 in the direction of the arrow by hand, and then take out the shift

shaft 

.

Notice:

Most parts of the box body are installed on the left crankcase. When disassembling, the

left crankcase must be down, otherwise the parts will fall off.

The gasket 

 is for one-time use. Once removed, it must be replaced, otherwise it will

cause oil leakage.

Before assembling the shift shaft, apply a proper amount of engine oil on the surface of

the part.

Before installing the box body, make sure that the box body assembly plane is smooth

and flat and apply a proper amount of sealant on the box body assembly plane. After
installing the new gasket 

, you need to apply the sealant again on both sides of the gasket

 according to the red line.
