4373861 Caterpillar rocker arm - the precise "commander" of the engine
In the complex operating system of the engine, although the rocker arm is small, it bears the responsibility of precise control of valve opening and closing, and the 4373861 Caterpillar rocker arm is undoubtedly one of the best!
This rocker arm is carefully crafted by Caterpillar with strict material selection. The rocker arm body is made of special aluminum alloy or high-strength alloy steel. The former reduces weight and improves heat dissipation, while the latter is reinforced with elements such as chromium, molybdenum, and vanadium, providing excellent hardness, high temperature resistance, and toughness. The rocker arm shaft is made of high-quality alloy steel, which has undergone special heat treatment to achieve both hardness and wear resistance.
Supported by advanced manufacturing technology, the forged rocker arm has a uniform internal structure and far superior fatigue resistance compared to traditional casting processes. Surface hardening treatment and precision grinding and polishing form a strong and wear-resistant layer on the surface of the rocker arm, with extremely low roughness, greatly reducing friction and wear, and extending its service life.
Adaptability is unparalleled, widely used in many Caterpillar equipment such as cold milling machines, wheel bulldozers, loaders, and pipe hoists. Whether in construction, mining, or industrial production, the 4373861 Caterpillar rocker arm can accurately "command" the valves, ensuring smooth engine intake and exhaust, and stable and efficient power output. Choosing it is a double insurance for engine performance and reliability, helping you travel smoothly in your career!
