Built to withstand harsh jobsite environments, this controller offers precise throttle response, stable speed regulation, and fault tolerance, ensuring smooth operation, lower emissions, and extended engine life. 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 EC210 EC240 EC290 EC330 20508011 Speed Sensor is a critical monitoring component for Volvo EC210, EC240, EC290, and EC330 excavators (widely used in construction, mining, and infrastructure projects). As the "speed detection core", it real-time tracks the rotational speed of key components like engines, hydraulic pumps, or drive motors—transmitting accurate speed signals to the excavator’s control unit. This ensures stable adjustment of power output during tasks like digging, lifting, and rock breaking, while preventing over-speed damage to components and maintaining optimal operational efficiency.
   Meeting Volvo OEM standards (part no. 20508011), it endures -30°C to 100°C temperatures, resists dust, vibration, and oil corrosion, and guarantees consistent signal transmission. Strict testing ensures seamless compatibility with the four Volvo models and long-term speed monitoring reliability.

   SPARKLING MACHINERY NEW CS56B CS68B CS74B CS78B 418-3837/360-3987 Piston Assy is a core engine combustion component for Caterpillar CS56B, CS68B, CS74B, and CS78B excavators (widely used in construction, mining, and infrastructure compaction tasks). As the "engine power generator", it moves reciprocally in the cylinder to compress fuel-air mixtures and transmit combustion force to the crankshaft—ensuring stable engine power output during high-intensity operations like heavy digging, rock breaking, and material handling, while maintaining efficient fuel combustion.
   Meeting Caterpillar OEM standards (part nos. 418-3837/360-3987), it endures -30°C to 200°C cylinder temperatures, resists high-pressure impact and wear, and guarantees airtight combustion chamber performance. Strict testing ensures seamless compatibility with the four Caterpillar models and long-term engine reliability.

The Caterpillar Coupling-Pump (Part No. 267-1082 / CA2671082 / 2671082) is a high-quality aftermarket replacement part made in China, engineered to fit CAT mini hydraulic excavators such as 305C CR, 305.5E, and certain Caterpillar wheel loader models.

This coupling serves as a crucial link between the engine and hydraulic pump, ensuring efficient power transmission while absorbing vibration and reducing stress on connected components. Built from durable elastomeric and metal materials, it offers excellent torsional flexibility and resistance to wear — helping maintain optimal machine performance.

If you're looking for a cost-effective yet reliable alternative to OEM parts, this China-made coupling is a smart choice for equipment maintenance and repair, without compromising functional integrity.
