Manufacturing technology ROTO 85 FS

 

  • Crank case (kit) – it is rough-worked of the cast at the CNC milling cutter. After that it is covered or slashed with a special colour. 

  • Cylinder (roll) – it is made of one piece of dural with pressed insole from the mild-granular cast iron, it is sharpened and honed to the correct size.  

  • Piston – it is casted from silicon alloy with one sealing circle. The aparature for the bung 8 mm is honed.  

  • Piston rod – it is forging, which is completely worked. Two needle focuses are moulded into piston rod, it is made for the piston and cranked bung.  

  • Crank shaft – it is made of one piece of steel, it is cemented and hardened and it is completely sharpened.
