Description

The 255-8664 516-0393 camshaft is a core valve train component specially designed for CAT C9.3 and C9.3B engines. Working in synchronization with the integrated camshaft gear, it undertakes the key responsibility of precisely controlling the opening and closing timing of the engine's intake and exhaust valves, and serves as the "power timer" to ensure the engine's power output, fuel efficiency and operating stability. This product is developed and manufactured in strict accordance with CAT's original drawings and technical standards. The cam profile curve, journal size, gear modulus and installation positioning datum are completely consistent with the original parts, and it is suitable for various equipment equipped with C9.3/C9.3B engines such as excavators, loaders, and generator sets. It is made of high-strength alloy steel through quenching and tempering, and the cam surface is strengthened by carburizing and quenching process, with a hardness of HRC58-62, which can effectively resist long-term high-frequency impact and wear; the gear tooth surface is processed by precision gear grinding, with high meshing precision, which can reduce transmission noise and power loss, ensure precise cooperation with the crankshaft timing system, and realize strict synchronization of intake and exhaust, fuel injection and piston movement. The product is easy to install, no need to modify the engine block or valve train, and can restore the normal working state of the engine by direct replacement, greatly shortening the equipment maintenance cycle.

Advantage

OEM-Level Adaptation, Easy Installation:1:1 replica of the original camshaft parameters of CAT C9.3/C9.3B engine, including key dimensions such as center distance, keyway specification, and gear meshing gap, all conform to OEM standards. It perfectly matches with engine cylinder head, valve lifter, timing chain and other components, no additional debugging is required after installation, avoiding valve timing disorder caused by adaptation issues.
High-Strength Material, Wear-Resistant and Durable:High-quality 42CrMo alloy structural steel is used as the base material, and through multiple heat treatment processes of "quenching and tempering + carburizing and quenching + low-temperature tempering", the tensile strength of the shaft body is ≥1080MPa, and the wear resistance of the cam working surface is increased by more than 60% compared with ordinary camshafts. The service life under normal working conditions can reach more than 20,000 hours, meeting the long-term high-intensity operation needs of heavy equipment.
Precise Valve Timing, Improved Energy Efficiency:The cam profile is processed by a five-axis machining center, with a profile accuracy error of ≤0.01mm, ensuring that the valve opening lift and duration are completely consistent with the original design. This enables sufficient intake and thorough exhaust in the engine cylinder, increasing combustion efficiency by 3%-5%, while reducing fuel consumption and harmful gas emissions by 1%-3% while enhancing power performance.
Stable Transmission, Low Noise and Energy Saving:The integrated camshaft gear adopts precision gear grinding technology, with a cumulative pitch error of ≤0.02mm, and the meshing stability meets the GB/T 10095.1-2008 Class 6 precision standard. The noise during transmission is less than 75dB, which is 10%-15% lower than ordinary gears, while reducing power transmission loss and improving the overall operating efficiency of the engine.

Performance

Dimensional Accuracy Index:Cam profile tolerance ≤0.015mm, journal roundness ≤0.005mm, journal cylindricity ≤0.008mm, gear tooth profile error ≤0.012mm, ensuring precise movement of the valve train and avoiding valve jamming or air leakage.
Mechanical Performance Parameters:Shaft Brinell hardness HB280-320, cam surface Rockwell hardness HRC58-62, gear surface hardness HRC55-58, impact toughness αk≥60J/cm², which can withstand high-frequency impact loads at the maximum engine speed of 2500rpm without deformation or fracture risk.
Valve Timing Accuracy:Intake valve opening advance angle error ≤±1°CA, exhaust valve closing lag angle error ≤±1°CA, valve overlap angle control accuracy ±0.5°CA, ensuring precise coordination with the fuel injection system and optimizing the combustion process.
Transmission Performance Index:Camshaft gear transmission efficiency ≥98.5%, meshing noise ≤75dB(A) at 2000rpm, gear tooth surface wear ≤0.003mm after 1000 hours of continuous operation, with excellent transmission stability.
High Temperature and Corrosion Resistance:Working temperature range -40℃ to 300℃, able to withstand the high temperature environment near the engine cylinder head; the surface is treated with phosphating + electrophoresis anti-rust, and the corrosion resistance of salt spray test is ≥480 hours, effectively resisting corrosion from oil impurities and condensed water.
