JS235 Slewing Drive by SPARKLING – Reliable Excavator Part

Heavy-Duty Swing Gearbox Reducer for Hitachi JS Excavators
Engineered for JS200, JS210, JS220, JS220LR, and JS235 excavators, the Swing Gearbox Reducer (JRC0007) is the precision heart of your machine’s rotation system. This OEM-compatible reducer delivers unmatched torque transmission and smooth 360° slewing motion under extreme loads. Forged with hardened helical gears and triple-sealed bearings, it resists wear, minimizes backlash, and withstands relentless job site vibrations. SPARKLING MACHINERY’s JRC0007 undergoes rigorous cycle testing to ensure perfect meshing alignment and extended service life – because precise rotation isn’t a luxury, it’s the core of your excavator’s productivity.

   SPARKLING MACHINERY NEW VOE14561971 VOE14561970 Gear Pump is a critical hydraulic power component designed for compatible construction machinery, such as excavators and loaders. As the "hydraulic power source" of the machinery’s hydraulic system, it converts mechanical energy from the engine into hydraulic energy by generating stable oil pressure and flow. This hydraulic energy drives key working mechanisms—including boom lifting, bucket digging, and arm rotation—ensuring smooth, powerful operation during heavy-duty tasks like construction earthmoving, mining loading, and infrastructure construction.

   Engineered to match original equipment performance standards, it maintains reliable hydraulic output even under harsh working conditions, such as high-pressure loads, continuous vibration, and temperature fluctuations. It prevents oil leakage and pressure loss, avoids inefficient hydraulic operation caused by flow instability, and safeguards the integrity of the entire hydraulic system. Backed by strict performance verification, it guarantees long-term stable power supply to support uninterrupted machinery operation.

   The ZGAQ-01236 joint housing cpl-rh (complete, right-hand) is a specific spare part manufactured by Hyundai HCE for use in their construction equipment, particularly the Hyundai R200W-7 wheel excavator.

Key Features
· OEM direct-fit design: Exact replication of mounting points, spline alignment, and seal interfaces for Hyundai R200W-7/R200W-7A—plug-and-play installation without modifications.
· Durable construction: High-strength cast steel housing (20CrMnTi alloy) and precision-machined sealing surfaces resist wear, impact, and corrosion, extending service life to 8,000+ hours.
· Sealed protection: NBR oil seals and O-rings prevent lubricant leakage and dust/water ingress, maintaining internal component integrity and reducing maintenance frequency.

Compatible Machines: Hyundai Wheel Excavators R200W-7, R200W-7A

   The S4S 804D-T 62KW diesel engine assembly is an OEM-compatible 4-cylinder turbocharged power core, exclusively engineered for Caterpillar 246C and 262B skid steer loaders.
