SPARKLING C11 Engine Pump Housing – Durable Excavator Part

The CATERPILLAR WATER PUMP HOUSING 223-9145 (CA2239145, 2239145) is a critical cooling system component designed for CAT Wheel Loaders 966H, 972H and C11 / C13 engine series. This part serves as the housing for the water pump, ensuring efficient coolant circulation and protecting the engine from overheating in high-demand operations.

Made from high-grade cast materials and precisely machined for a secure fit, this housing guarantees durability and leak-free performance even under the harshest working conditions. It's a reliable replacement for worn or damaged pump housings, restoring your engine’s cooling efficiency and extending the service life of your machine.

   SPARKLING MACHINERY NEW 440-00257 Cylinder;Arm is a dedicated hydraulic actuation component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s arm movement system, it converts hydraulic pressure into linear force to drive the arm’s lifting, lowering, and extending actions—supporting critical on-site tasks like digging, material grabbing, and precision placement in construction, mining, or infrastructure projects. This function is essential for maintaining the machinery’s operational flexibility and load-bearing capacity, directly ensuring smooth coordination between the arm and bucket, and preventing movement lag or jams that could reduce work efficiency or cause safety hazards.

   Engineered to match original equipment performance standards, it maintains stable pressure retention and smooth piston movement even under harsh working conditions, including heavy load stress (up to rated 500 kN), continuous vibration, and exposure to dust or hydraulic oil contaminants. It resists internal leakage and cylinder wall wear, avoiding hydraulic system inefficiencies that lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable arm actuation to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW R140W7 R140W7A R170W7 XKBF-00100 Lock Valve Kit-A is a dedicated, high-precision hydraulic safety assembly exclusively engineered for HITACHI R140W7, R140W7A, and R170W7 wheeled excavators—versatile equipment widely used in road construction, municipal engineering, and urban infrastructure projects. As a core safety component of the excavator’s hydraulic system, it locks the position of key mechanisms (boom, arm, bucket) when the excavator is stationary or during operator breaks, preventing accidental movement caused by hydraulic pressure loss. This function is vital for protecting on-site workers, avoiding equipment collisions, and ensuring operational safety during tasks like road repair, material handling, and urban demolition.

   Engineered to meet HITACHI’s original equipment (OEM) standards and marked with the genuine part number XKBF-00100, the Lock Valve Kit-A withstands harsh working conditions: high hydraulic pressure (up to 32 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from on-road travel and off-road work. It resists oil contamination and mechanical wear, providing long-lasting safety protection for the three HITACHI wheeled excavator models. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily excavator tasks.

The Caterpillar Swing Reducer (Part No. 333‑3073 / 3333073) is a premium swing gearbox designed to restore smooth and powerful 360° rotation in CAT excavators—compatible with 312D, 312DL, 312D2, 312E, 313D, 313D2, 314C, and 314E models. 

It features hardened steel planetary gears, sealed bearings, and robust housing to handle heavy-duty rotational loads while preventing leaks and contamination . Available as genuine OEM or high-quality aftermarket units, this swing reducer ensures a direct-fit replacement and optimized machine performance.
