The sleeve (Ø 130.00 mm) is used for YaMZ family engines(//tractor-service.com)
Production of castings - by centrifugal method, to obtain a high-quality structure of the material and high mechanical properties. To increase wear resistance, the inner working surface is hardened to high hardness by high-frequency currents (HFC) and processed by the plateau honing method, the roundness tolerance of the hole is no more than 0.008 mm. 
Material: special alloyed cast iron.
Weight: 8.3 kg

Piston 236-1004015Д
Piston 236-1004015D (piston group Ø 130.00 mm) is intended for engines of the YaMZ family.
