SPARKLING Cat Excavator Auxiliary Valve – Durable & Precise

The Valve GP‑Manual (Cat part no. 389‑2407 / CA3892407) is a rugged manual auxiliary shut‑off valve designed for use in heavy-duty Caterpillar excavators—specifically models 352, 323F, 320C, 320D SA, M325D MH/L, 355, and more. It provides dependable two-way hydraulic shut-off control, helping protect critical systems during maintenance or attachments handling. Built to OEM tolerance, this valve ensures reliable operation in the harshest environments, available both as a genuine Cat part and high-quality aftermarket alternative.

   SPARKLING MACHINERY NEW 324D 330D 336D 336D2 2968060 Pressure Sensor is a dedicated precision monitoring component exclusively designed for 324D, 330D, 336D, and 336D2 excavators. As a core part of the excavators’ hydraulic and engine systems, it real-time detects critical pressure data—such as hydraulic system pressure and engine oil pressure—and transmits accurate signals to the operator’s control panel. This function is critical for preventing overpressure-related failures during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance, directly ensuring stable hydraulic power output, protecting valves and pumps from pressure damage, and avoiding unplanned downtime caused by pressure anomalies.

   Engineered to match original equipment performance standards, it maintains high detection accuracy even under harsh working conditions, including high oil pressure (up to 40 MPa), continuous excavator vibration, and exposure to hydraulic oil or dust. It resists signal interference and corrosion, avoiding data errors that could lead to misjudgments of the excavator’s operating status. Backed by strict performance verification, it guarantees reliable pressure monitoring to support uninterrupted operation of 324D/330D/336D/336D2 excavators.

   The 280-2357 gear is a planetary final drive reduction gear for Caterpillar mini excavators 303.5C/303.5D/303.5E (also fits 303C CR/303.5CR/303.5E2/304/304E2). It works in the travel motor gearbox to reduce speed, amplify torque, and drive track movement smoothly for landscaping, utility, and small-scale construction tasks.
