spray out when disconnecting.
b) Keep fire and open flame away from the fuel
area.
After disconnecting the fuel hoses, plug them to avoid
fuel leakage.
Clutch release cylinder
Remove the clutch release cylinder with the pipe still
connected; then avoid the cylinder.

DISASSEMBLY
1. Remove in the sequence shown in the figure referring to the disassembly note for specially marked
parts.
2. Code all identical parts (such as pistons, piston rings, connecting rods, and valve springs) so that

3. Clean the parts with steam, blow off any remaining water with compressed air.
Note
Care should be taken during the disassembly of any part or system to study its order of
assembly. Any deformation, wear, or damage should also be noted.
