SPARKLING Caterpillar Bulldozer Hydraulic Parts – Reliable & Precise

The CA1878636 Main Control Valve Assembly (also referenced as 187-8636 or 1878636) is an essential hydraulic component designed specifically for the Caterpillar D9R track-type tractor. This unit is responsible for the precise distribution and regulation of hydraulic flow, enabling smooth and accurate control of blade, ripper, and other operational functions.

Key Features:

• Direct-fit replacement for CAT D9R – no modification required

• OEM-standard internal machining ensures optimal hydraulic flow and durability

• High-pressure resistance for demanding dozer applications

• Fully tested before delivery, ensuring performance and zero leakage

Whether you're maintaining a mining fleet or servicing a heavy-duty bulldozer, this main control valve assy ensures efficient operation and extended equipment lifespan.

   SPARKLING MACHINERY NEW 201-45342 201-46298 Fuel Pump is a critical engine fuel supply component designed for a wide range of excavator models (widely used in construction, mining, municipal engineering, and large-scale earthmoving projects). As the "engine fuel core", it precisely pressurizes and delivers diesel fuel to the combustion chamber—ensuring stable, consistent fuel flow during high-intensity tasks like heavy digging, rock breaking, and long-hour equipment operation, while optimizing fuel atomization to maintain efficient combustion and avoid engine power loss.
   Meeting industry OEM standards (part nos. 201-45342 / 201-46298), it endures -30°C to 120°C working temperatures, resists diesel fuel corrosion and equipment vibration, and guarantees reliable fuel pressure output (rated pressure deviation <0.2 bar). Strict performance testing ensures seamless compatibility with applicable excavator models and long-term stability of the engine fuel system.

   SPARKLING MACHINERY NEW EC120D EC140B EC140C EC140D EC140E 14524582 Relief Valve is a dedicated hydraulic safety component for VOLVO EC120D, EC140B, EC140C, EC140D, and EC140E crawler excavators (mid-sized equipment for construction, municipal engineering, and light mining). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during trench digging, material loading, and small-scale rock breaking.

   Meeting VOLVO OEM standards (part no. 14524582), it endures 30 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.

   SPARKLING MACHINERY NEW A35E EC330B EC330C EC360B L220F PL4608 VOE21243114 Rocker is a key operational component for 6 Volvo heavy equipment models (mining/construction use). It enables precise actuation of core functions (e.g., hydraulic controls, auxiliary operations) with responsive performance, ensuring smooth equipment maneuvering. 
   Meeting Volvo OEM standards (VOE21243114), it resists -30°C to 85°C temps, wear, and vibration, guaranteeing seamless compatibility and long-term reliable operation.
