SPARKLING CAT D9R Main Control Valve – Precision Hydraulic Valve

The CA1878636 Main Control Valve Assembly (also referenced as 187-8636 or 1878636) is an essential hydraulic component designed specifically for the Caterpillar D9R track-type tractor. This unit is responsible for the precise distribution and regulation of hydraulic flow, enabling smooth and accurate control of blade, ripper, and other operational functions.

Key Features:

• Direct-fit replacement for CAT D9R – no modification required

• OEM-standard internal machining ensures optimal hydraulic flow and durability

• High-pressure resistance for demanding dozer applications

• Fully tested before delivery, ensuring performance and zero leakage

Whether you're maintaining a mining fleet or servicing a heavy-duty bulldozer, this main control valve assy ensures efficient operation and extended equipment lifespan.

   SPARKLING MACHINERY NEW 4469057 Core is a core functional component for Hitachi ZX110/ZX130H/ZX130K/FV30/ZX120 excavators (construction/mining use). It supports critical system operations (hydraulic/thermal management) with stable performance, meeting Hitachi OEM standards (4469057). Resistant to -30°C to 120°C temps, corrosion, and operational stress, it ensures seamless compatibility and reliable long-term functionality for heavy-duty workflows.

    SPARKLING MACHINERY NEW EC240C EC250D EC250E EC290B EC300E 14596398 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC240C, EC250D, EC250E, EC290B, and EC300E crawler excavators—heavy-duty equipment critical for large-scale construction, mining, and infrastructure projects. As a core protective component for the excavators’ high-pressure hydraulic systems, it covers key areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of high-load mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, gravel, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity tasks like rock breaking, bulk material loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty excavator vibration. It resists oil aging and wear, providing long-lasting protection for the hydraulic systems of EC240C/EC250D/EC250E/EC290B/EC300E models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

   SPARKLING MACHINERY NEW 334/C2147 Radiator is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is vital for maintaining the engine’s optimal operating temperature (typically 82–95°C), which directly influences fuel efficiency, power output, and the long-term service life of key engine components.

   Engineered to match original equipment performance standards, it retains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and constant machinery vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to costly engine damage or unplanned downtime. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of compatible heavy-duty machinery.
