SPARKLING Aftermarket Bulldozer Parts – Durable & Precise

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.

   SPARKLING MACHINERY NEW 11221161 Cylinder Head is a core engine component for Volvo excavators (heavy-duty construction/mining use). It seals the engine cylinder top, houses valves, and ensures efficient combustion by maintaining compression. 
   Meeting Volvo OEM standards (11221161), it resists up to 300°C high temps, pressure, and corrosion, ensuring seamless compatibility and long-term reliable engine performance.

   SPARKLING MACHINERY NEW EC160B EC180B EW160B 14589157 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC160B, EC180B excavators, and EW160B wheeled excavators—versatile equipment widely used in construction, municipal maintenance, and light mining projects. As a core protective component for the machinery’s hydraulic systems, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, debris, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during tasks like trench digging, material loading, and road maintenance.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous machinery vibration. It resists oil aging and wear, providing long-lasting protection for the hydraulic systems of EC160B/EC180B/EW160B models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO machines.

   SPARKLING MACHINERY NEW EC120D EC135B EC140B EC140C EC140D 14591545 Pressure Switch is a key hydraulic safety component for Volvo EC120D, EC135B, EC140B, EC140C, and EC140D excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic pressure sentinel", it real-time monitors pressure changes in hydraulic circuits—automatically triggering alerts or protective actions via the excavator’s control unit when pressure goes beyond safe limits. This prevents overpressure damage to pumps, valves, and cylinders during tasks like digging or boom lifting, while ensuring stable operation by avoiding underpressure-related function failures.
   Meeting Volvo OEM standards (part no. 14591545), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees precise pressure sensing. Strict testing ensures seamless compatibility with the five Volvo models and long-term hydraulic system safety.
