SPARKLING 1586634 CAT Excavator Part

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 ZGAQ-02885 AXLE-DIFFERENTIAL is a high-performance replacement component designed for Hyundai wheel excavators R140W-9, R160W-9A, R170W-9, and R180W-9S. As the heart of the machine's drive system, the differential ensures power is efficiently distributed to the wheels, enabling smooth turns, stable operation, and strong traction even in demanding terrains.

Manufactured with high-precision machining and heavy-duty materials, this differential unit is engineered to match OEM specifications and withstand the harsh conditions of construction, mining, and industrial applications. It is an ideal choice for restoring full drivetrain performance and reliability in your equipment.

   SPARKLING MACHINERY NEW D6T 270-1762 270-1763 Gear Pump is a premium China-made hydraulic component engineered as a critical power transmission unit for compatible machinery.  As a core part of hydraulic systems, it delivers consistent fluid pressure to drive essential operations such as lubrication, control, and auxiliary functions, ensuring smooth performance in construction, agriculture, and heavy-duty equipment.

   Designed to original equipment standards, it maintains stable flow output even under continuous operation, minimizing energy loss and optimizing system efficiency.  Equipped with advanced pressure regulation and leak-resistant systems, it adapts to harsh working environments, from dusty job sites to high-temperature conditions.  Backed by strict quality verification and professional support, it reduces unplanned downtime and maximizes equipment productivity.

   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.
