Product description


Conrod Bush SEMI Kolbenschmidt 77797690

Description

The SEMI conrod bush by Kolbenschmidt is a precision-engineered component designed for Cummins C-Series diesel engines and widely used in construction, industrial and agricultural machinery. Its function is to ensure the correct connection between the piston pin and the connecting rod, reduce friction, and protect engine components against premature wear. Manufactured from high-strength alloys, the bush withstands high loads and operating temperatures, ensuring extended engine service life.

Technical Data

  • Part number: 77797690
  • Manufacturer: Kolbenschmidt
  • Type: conrod bush set (Cummins C-Series)
  • Material: high-strength bearing alloy
  • Inner and outer diameter: according to Cummins C-Series specification
  • Temperature resistance: up to 250°C
  • Quality standard: ISO/TS 16949

Application

The SEMI conrod bush is used in Cummins C8.3, ISC, QSC, QSL, ISL engines and other applications installed in machines from Komatsu, JCB, Terex, New Holland, Tigercat, Zettelmeyer and Dressta. It is suitable for wheel loaders, excavators, dump trucks, forestry and road machinery. Replacing worn bushes restores proper geometry of the crank-piston system, reduces vibrations and fuel consumption, and increases engine durability.

Properties

  • Precise fit – guarantees proper piston pin guidance.
  • Wear resistance – ensures long service life even under heavy duty conditions.
  • Thermal stability – retains strength at high working temperatures.
  • Easy replacement – compatible with Cummins OEM engines and machinery.
  • Noise and vibration reduction – improves comfort and performance of the engine.

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
