SPARKLING 187-8636 Control 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.

The CA2003373 (200-3373 / 2003373 / 200-3372) Swing Motor GP is a high-performance OEM replacement designed for Caterpillar excavator models CAT330C, CAT330D, CAT330DL, and CAT336D. Engineered for exceptional torque output, smooth swing control, and long-lasting durability, this swing motor is built with precision-machined components and superior sealing technology. It ensures optimal hydraulic efficiency and responsiveness, even in the toughest construction and mining conditions.

Tested to meet or exceed OEM performance standards, this Motor Group – Swing is the ideal solution for heavy-duty excavation tasks, helping maximize machine uptime and productivity while reducing operating costs.

   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 0501.206.521 Joint Double is a dedicated hydraulic connection component for Komatsu excavators (widely used in construction, mining, and infrastructure projects). As the "hydraulic pipeline linker", it connects two hydraulic tubes to ensure smooth, leak-free oil flow between system components—supporting key functions like boom lifting, bucket digging, and swing movements, while adapting to the excavator’s operational vibration and spatial layout.
   Meeting Komatsu OEM standards (part no. 0501.206.521), it endures 30 MPa working pressure, -30°C to 95°C temperatures, resists hydraulic oil corrosion and wear, and maintains tight connection performance. Strict testing guarantees seamless compatibility with applicable Komatsu models and long-term hydraulic system stability.
