Connecting Rod 331-0290 C7.1-1 For CAT Engine C6.6 C4.4

Product Name: Engine Connecting Rod

Fit for Engine: CAT C7.1, C7.1-T four-cylinder industrial diesel engine

• Construction machinery: CAT 320GC excavators, small road rollers, wheel loaders
• Agricultural equipment: Large farm tractors, irrigation pump units
• Industrial forklift: 3–5 ton CAT powered forklift trucks
• Generator sets: 60–100kW stationary diesel generator units

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 construction operation, effectively avoiding bending, fracture and permanent deformation faults under long-time heavy-duty working conditions.

2. Industrial-Grade Premium Raw Materials

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

3. 100% OEM Precise Matching

   All machining surfaces are manufactured strictly per original factory OEM specifications with high-precision CNC boring and milling. The small end bushing hole, big end bearing hole and bolt mounting position fully fits CAT C7.1 and C7.1-T 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 C7.1 series diesel engines, extending the overall service life of construction and agricultural equipment.

We support multiple reliable shipping methods, including SF Express, YTO, ZTO and EMS. All products are strictly inspected before delivery with anti-rust oil and moisture-proof wrapping paper, complete tracking information to ensure fast and safe global delivery.

Import duties, local taxes and additional handling charges are not included in the listed price and freight. All related customs fees are borne by the buyer, subject to local customs policies and regulations.

This professional heavy-duty connecting rod is customized for CAT C7.1 / C7.1-T four-cylinder industrial diesel engines, widely used in CAT excavators, tractors and industrial forklifts. With alloy steel forging, complete heat treatment, OEM-level dimensional accuracy and long fatigue life, it is the cost-effective spare part for engine overhaul, greatly cutting maintenance downtime and parts procurement costs.
