Connecting Rod 1139016 C10-C12-1 For CAT Engine C10 C12

Product Name: Engine Connecting Rod

Fit for Engine: CAT C10, C12, C10-C12-1 six-cylinder heavy-duty diesel engine

• Heavy-duty highway semi-trailer trucks, long-distance transport vehicles
• Construction machinery: Large wheel loaders, excavators, road rollers
• Industrial power equipment: 240–330kW stationary diesel generator sets
• Bus & coach, special engineering vehicles

1. High Load Bearing Integrated Forging Structure

   This connecting rod adopts one-piece hot forging integral forming process, with thickened rod body and reinforced I-beam structure. It can bear ultra-high impact load and explosion pressure during long-hour heavy transport and construction operation, effectively avoiding bending, fracture and permanent deformation faults.

2. Industrial-Grade Premium Raw Materials

   Made of high-strength alloy steel with overall quenching and tempering heat treatment. The material features excellent tensile resistance, fatigue resistance and wear resistance, adapting to harsh long-distance transportation and construction site environments, greatly extending service life.

3. 100% OEM Precise Matching

   All connecting rods are manufactured strictly per original factory OEM specifications with high-precision CNC boring and milling. Every small end bushing hole, big end bearing hole and bolt mounting position fully fits CAT C10, C12 and C10-C12-1 engines. No grinding or modification required during installation, realizing seamless assembly and zero assembly error.

4. Precision Double Bearing Bush Matching Design

   The small end is pre-installed with wear-resistant copper bush, and the big end adopts split high-load bearing bush matching structure. The inner hole is precisely ground to form uniform lubricating oil film, effectively reducing friction loss between piston pin and crankshaft journal, preventing shaft holding and burning tile failure.

5. Restore Factory-Standard Engine Performance

   Complete connecting rod replacement stabilizes engine compression ratio, eliminates power drop, unstable idling and excessive fuel consumption caused by rod deformation and excessive clearance. It fully recovers original power output, combustion efficiency and working stability of CAT C10/C12 series diesel engines, extending the overall service life of heavy-duty vehicles and construction equipment.
