SPARKLING RD551‑64052 – Reliable Excavator Undercarriage Part

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.

   SPARKLING MACHINERY NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 Crankshaft Main Bearing is a critical engine load-bearing and lubrication component for Caterpillar 416F, 420F, 428F, 430F, 432F, 434F, and 444F excavators (widely used in construction, mining, and municipal infrastructure projects). As the "crankshaft stability anchor", it supports the crankshaft’s rotational motion, reduces friction between the crankshaft and engine block, and absorbs radial loads from power transmission—ensuring smooth engine operation during high-intensity tasks like digging, heavy lifting, and rock breaking, while protecting core engine parts from wear.
   Meeting Caterpillar OEM standards (part no. 360-3988), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains consistent lubrication performance. Strict testing guarantees seamless compatibility with the seven Caterpillar models and long-term engine reliability.

The Caterpillar Switch GP-Toggle (Part No. CA1586634 / 158-6634 / 1586634) is a genuine OEM electrical component used in various CAT track loaders and excavators, including models 963D, 973D, 953D, 330D MH, and 325D.

Manufactured from high-quality polyamide plastic, this toggle switch is engineered to provide durable performance, electrical reliability, and resistance to heat, wear, and vibration — all critical for heavy-duty applications. It plays a key role in controlling specific machine functions from the operator cab, offering responsive switching and long operational life.

This part is an ideal replacement for worn or faulty switches in your Caterpillar equipment. Its precise fit and OEM-grade construction ensure hassle-free installation and consistent performance in demanding jobsite conditions.

The K9001659 Pinion Gear is a precision-machined drive component specifically designed for DOOSAN excavators including DX140W, DX170W, DX190W, and SOLAR 185W-V models. As an essential part of the drivetrain system, this pinion gear engages seamlessly with bevel or ring gears to transmit torque efficiently in swing or travel devices.

Built with heat-treated alloy steel and advanced CNC gear-cutting technology, this gear ensures high strength, minimal backlash, and long-lasting performance even under heavy-duty operations.
