Disassemble of Sram X0 shifters

I bought this shifter from a guy from Europe, it seems that the shifter has problem from shifting. and this cost me  for USD100 from ebay, its kinna expansive for a 2nd hand shifter. so i decided to disassemble the whole thing.

This is the breakdown of sram x0 shifter, it took me few minutes to disassemble it, and took me 10minutes to assemble back to perfect condition. i cleaned and re-lube the whole thing and now it works perfectly
