SPARKLING Excavator Transmission Gear – Durable & Precise

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.

   SPARKLING MACHINERY NEW R210-7 R220-7 R250-7 R290-7 R305-7 R335-7 11Q6-90040 Compressor Assy is a dedicated air conditioning core component for Hyundai R210-7, R220-7, R250-7, R290-7, R305-7, and R335-7 crawler excavators (widely used in construction, mining, and infrastructure projects). As the "cooling power source" of the excavator cab, it compresses refrigerant to maintain stable temperature control—ensuring a comfortable operating environment for operators during long-hour tasks in high-temperature or harsh weather.
   Meeting Hyundai OEM standards (part no. 11Q6-90040), it endures -20°C to 80°C temperatures, resists vibration and refrigerant corrosion, and maintains consistent cooling efficiency. Strict testing guarantees seamless compatibility with the six Hyundai models and long-term reliable cab air conditioning performance.

   SPARKLING MACHINERY NEW HL757-F HL757TM-F HL760-F 100-7C-2 Cross Joint is a dedicated transmission linkage component exclusively designed for HL757-F, HL757TM-F, and HL760-F wheel loaders. As a core part of the loaders’ drivetrain system, it enables flexible power transmission between connected rotating shafts (e.g., between the gearbox and drive axle), accommodating angular misalignments and axial movements during heavy-duty operations like material loading, stockpiling, and construction site material handling. This function is critical for maintaining smooth drivetrain operation, reducing mechanical stress on shafts and bearings, and preventing transmission jams that could lead to sudden equipment shutdowns or component damage.

   Engineered to match original equipment performance standards, it maintains strong torque-bearing capacity and rotational flexibility even under harsh working conditions, including continuous vibration, heavy load stress, and exposure to dust or muddy debris. It resists wear and joint looseness, avoiding transmission inefficiencies or failures that result in unplanned downtime. Backed by strict performance verification, it guarantees reliable power transfer to support uninterrupted operation of HL757-F/HL757TM-F/HL760-F wheel loaders.

The CATERPILLAR COVER ASSY 4T-1572 is a robust and precision-engineered component designed for heavy-duty CAT machines, including models like 772B, 768C, 773D, 775F, and 773F. This cover assembly plays a critical role in protecting internal systems from dust, moisture, and impact in demanding working environments. Manufactured with high-strength materials and built to OEM standards, it offers reliable sealing and long-lasting performance.

Compatible part numbers include 4T-1572, 4T1572, and CA4T1572. Whether for maintenance or replacement, this part ensures a perfect fit and optimal function, helping reduce downtime and extend equipment life.
