The Kubota Oil Cooler (part nos. RD451‑64050, RD451‑64053, RD551‑64050, RD551‑64052) is a premium hydraulic oil radiator engineered for various Kubota excavators and compact machines, including models like KX057‑4, U48‑4, U55‑4, and more. This high-performance aluminium oil cooler ensures efficient heat dissipation and maintains optimal hydraulic oil temperatures under continuous heavy-duty operation. Manufactured to OEM standards and available in both genuine and aftermarket options, it offers excellent durability, corrosion resistance, and a perfect drop-in fit.

   The 8-97622719-4 Injector Nozzle is a high-precision fuel injection component engineered for Isuzu 6UZ1 diesel engines, and perfectly matched to John Deere 470GLC and Hitachi Zaxis470LC-5B heavy excavators. It delivers atomized fuel into combustion chambers with consistent pressure and spray pattern, ensuring efficient fuel combustion, optimized power output, and reduced emissions. 

Key Features
· OEM-Matched Precision: Denso-engineered, 6-hole spray design with 0.28mm diameter nozzles, ensuring consistent fuel atomization and combustion efficiency.
· High-Temp Resistant: Chrome-plated needle valve and heat-treated alloy body withstand 2000+ bar injection pressure and extreme combustion temperatures.
· Leak-Proof Sealing: Dual O-ring design and lapped needle-seat interface prevent fuel leakage, reducing waste and emissions.
· Drop-In Replacement: Direct-fit for Isuzu 6UZ1 engines and compatible excavators—no calibration or modification needed for installation.

· Application: It is intended for use in Isuzu 6UZ1 and potentially 6WF1 diesel engines, which power various heavy-duty equipment.
· Compatible Machinery: The injector is used in machinery such as the John Deere 470GLC excavator and the Hitachi Zaxis470LC-5B excavator.

The SPARKLING Wheel Excavator Carrier Disc (4472.377.037) fits models R130W-3, R170W-3, R170W-7. Designed as a durable Clutch Carrier and Planetary Disc, it ensures optimal transmission performance and reliability. Trusted for heavy-duty excavator clutch systems.

Part number 4472.377.037 (also written as 4472-377-037) is a Carrier Disc (sometimes called a Clutch Disc Carrier) manufactured by ZF, primarily used in the axle assemblies of Hyundai and Doosan/Daewoo wheel excavators.

The 4472.377.037 Carrier Disc is a high-precision drivetrain component located within the axle's planetary or braking group. It acts as a supporting plate for friction discs or gear sets, ensuring stable torque transfer and effective braking performance in heavy-duty wheel excavators. Designed for durability under high stress, it is a vital part for maintaining the axle integrity of machines like the Hyundai R170W-7 and Doosan S160W-V.

Model Compatibility:
Hyundai: R130W-3, R170W-3, R170W-7, R170W-9, R210W-9.
Doosan/Daewoo: S130W-V, S140W-V, S160W-V, S170W-V

   SPARKLING MACHINERY NEW R290LC9 R290LC9MH R300LC9A 39Q8-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R290LC9, R290LC9MH, and R300LC9A excavators. As a critical part of the swing system, it transforms high-speed, low-torque input into low-speed, high-torque output, enabling smooth and precise rotation of the upper structure (boom, arm, and bucket) during positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
