Whether you're replacing a faulty unit or upgrading your engine control system, this governor controller is a reliable and cost-effective solution.

Compatible with a wide range of construction equipment, it is easy to install and integrates seamlessly into your machine’s electronic control system.

   SPARKLING MACHINERY NEW 349 352 5681695 Hose is a dedicated hydraulic fluid transfer component for Caterpillar 349 and 352 crawler excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "hydraulic fluid conduit" of the excavator, it efficiently transports high-pressure hydraulic oil between critical components like pumps, valves, and cylinders—ensuring stable oil supply for heavy-duty functions such as rock breaking, deep digging, and boom lifting, while eliminating leak risks that disrupt operations.
   Meeting Caterpillar OEM standards (part no. 5681695), it withstands 35 MPa working pressure, operates in -30°C to 95°C temperatures, resists hydraulic oil corrosion and external abrasion, and maintains flexibility for easy installation. Strict testing guarantees seamless compatibility with Caterpillar 349/352 and long-term hydraulic system reliability.

   SPARKLING MACHINERY NEW R170W-9S R180W-9S 21Q5-32210 MCU Controller is a premium China-made intelligent control core specifically engineered for R170W-9S and R180W-9S wheel excavators. As the "brain" of the machinery, it orchestrates critical operational systems by processing real-time data from sensors, regulating engine performance, hydraulic flow, and auxiliary functions to ensure synchronized and efficient equipment operation.

   Designed to original standards, it delivers stable signal transmission and precise control responses even in harsh working environments, from dusty construction sites to high-vibration conditions. With advanced programming and adaptive algorithms, it optimizes fuel efficiency, reduces operational errors, and enables quick system diagnostics. Backed by strict quality verification, it ensures consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 312E 320E 324E 329E 3576475 Fuel Transfer Pump is a dedicated fuel system component exclusively designed for 312E, 320E, 324E, and 329E excavators. As the core of the excavators’ fuel supply chain, it efficiently transfers fuel from the fuel tank to the engine’s injection system—ensuring a steady, pressure-stable fuel flow to support optimal combustion during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance. This function is vital for maintaining consistent engine power output, preventing fuel starvation (which causes sudden power drops or stalling), and protecting the injection system from damage due to insufficient fuel supply.

   Engineered to match original equipment performance standards, it maintains reliable fuel transfer efficiency even under harsh working conditions, including extreme temperatures (-30°C to 80°C), continuous excavator vibration, and exposure to fuel contaminants or construction site dust. It resists fuel leakage and internal component wear, avoiding fuel system failures that could lead to costly engine repairs or unplanned downtime. Backed by strict performance verification, it guarantees consistent fuel delivery to support uninterrupted operation of 312E/320E/324E/329E excavators.
