[2] DISASSEMBLY/ ASSEMBLY
[2]-15. Cylinder, Piston
DISASSEMBLING
(1) Remove "Air filter, Carburetor, and Intermediate flange" as mentioned in [2]-10. (Figs. 23, 24, 25, and 26)
(2) Piston set can be separated from Crank shaft by removing Ring spring 8 from Piston with Long-nose pliers. (Fig. 39)
ASSEMBLING
Note: Supply 2-stroke engine oil to Piston and the inside of Cylinder in advance.
Important: See Figs. 39 and 40.
• Set Piston in place with the arrow marking faced to Muffler side.
• Face the gap of Piston ring 38 to Carburetor side. Make sure that a small projection in Piston groove comes
in the gap of Piston ring 38.
• Ring spring 8 and Piston pin 8 have to be installed into Piston through Needle cage 810 and Crank shaft from
Guide bar side.
• Be sure to use New Gasket (Fig. 11) and New Crank case sealing.
• When replacing Ball bearing 6201, press-fit the inner ring portion to Crank shaft using the same size pipe
and a block for placing the counterweights without bending.
After the above steps, reverse the disassembling procedure of "DISASSEMBLY of [2]-11. Tank assembly.
