High Strength and Durability CONROD ASSEMBLY for Perkins C7.1 Excavator Diesel Engine with High Precision Matching and Reliable Sealing Performance

For T406141 CONROD ASSEMBLY Perkins  C7.1 Excavator Diesel Engine Parts

Specification

Description

This product is a connecting rod assembly designed for C7.1 excavator diesel engines, serving as one of the core moving components of the engine. It is mainly responsible for converting the linear reciprocating motion of the piston into the rotary motion of the crankshaft to achieve efficient power transmission. The product is formed by precision forging, followed by high-precision machining and heat treatment strengthening, ensuring structural strength and dimensional accuracy, and can stably adapt to the high-load operating conditions of the engine.

Advantage

High Strength and Durability: Forged from high-quality alloy materials, it has excellent fatigue resistance, can withstand long-term high-speed and heavy-load operating conditions of the engine, and effectively prolongs service life.
High Precision Matching: Key mating parts (big/small end shaft holes, end faces) are precision machined, ensuring precise fit clearances with the piston and crankshaft, guaranteeing smooth power transmission, and reducing vibration and abnormal noise.
Reliable Sealing Performance: The connecting rod cap and rod body are locked with special bolts through precise positioning and fastening design, ensuring no looseness or leakage during operation and improving operational stability.
Strong Adaptability: Specially designed for the target engine model, with fully matched structural dimensions and installation interfaces, it can be directly replaced without additional modification, reducing maintenance costs and downtime.
Stable Operating Performance: Optimized structural design and material ratio effectively reduce motion inertia, improving engine fuel economy and power output efficiency.

Performance

Material Performance: Made of high-strength alloy structural steel, with tensile strength ≥900MPa, yield strength ≥700MPa, excellent impact toughness, and adaptability to extreme temperature and load changes.
Precision Index: Coaxiality of big and small ends ≤0.02mm, roundness and cylindricity of shaft holes ≤0.01mm, ensuring the matching accuracy of motion pairs and reducing friction loss.
Fatigue Life: Passed bench accelerated fatigue test, it can operate stably for ≥10,000 hours under rated working conditions, meeting the long-term operation needs of construction machinery.
Power Transmission Efficiency: Optimized cross-section and mass distribution reduce reciprocating inertia force by more than 10%, improving engine speed response and smoothness of power output.
Environmental Adaptability: It can work stably in the ambient temperature range of -40℃~120℃, adapting to various complex operating scenarios of excavators.

Application Scenario

This connecting rod assembly is mainly used in C7.1 series excavator diesel engines, and is widely applicable to heavy construction machinery fields such as mining, infrastructure construction, and road construction, providing stable and reliable power transmission guarantee for equipment.
