   SPARKLING MACHINERY NEW 6675-31-1011 Crankshaft is a critical power transmission component tailor-made for compatible heavy-duty diesel engines used in excavators, loaders, and industrial machinery. As the "rotational core" of the engine, it converts the reciprocating motion of pistons into continuous rotational torque, which drives the machinery’s hydraulic systems, undercarriage, and working mechanisms. This function is essential for delivering consistent power to support heavy-duty tasks like deep digging, large-volume material lifting, and continuous mining operations.

   Designed to meet original equipment performance standards, it maintains stable operation even under extreme conditions—including high rotational speeds, intense mechanical loads, and temperature fluctuations. It ensures smooth torque transfer with minimal vibration, preventing premature wear of engine components and safeguarding long-term operational efficiency. Backed by strict performance verification, it guarantees reliable power output to minimize engine downtime and keep heavy machinery running continuously.

   SPARKLING MACHINERY NEW EC240B EC240C EC250D EC290B EC290C 14601385 Seal Kit is a dedicated, heavy-duty sealing solution exclusively designed for VOLVO EC240B, EC240C, EC250D, EC290B, and EC290C crawler excavators—core equipment in large-scale construction, mining, and infrastructure development projects. As a critical protective component for the excavators’ high-pressure hydraulic systems, it covers key areas such as hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of high-load mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, gravel, 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 high-intensity tasks like rock breaking, bulk material loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty excavator vibration. It resists oil aging and material wear, providing long-lasting protection for the hydraulic systems of EC240B/EC240C/EC250D/EC290B/EC290C models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

   SPARKLING MACHINERY NEW M313C M313D M315C 249-0974 Oil Filter Head is a dedicated hydraulic/engine system component exclusively designed for M313C, M313D, and M315C wheel loaders. As a core part of the machinery’s oil filtration system, it serves as the critical connection between the oil filter and the oil pipeline—securing the filter in place while directing oil flow through the filter media to remove contaminants (e.g., metal particles, sludge). This function is essential for maintaining oil cleanliness, protecting key components like hydraulic pumps, valves, and engine bearings from abrasive wear, and ensuring stable operation during heavy-duty tasks such as material loading, site grading, and construction waste handling.

   Engineered to match original equipment performance standards, it maintains tight sealing and stable oil flow even under harsh working conditions, including continuous vibration, high oil pressure, and temperature fluctuations (-20°C to 80°C). It resists oil leakage and corrosion from oil additives, avoiding system contamination or pressure loss that could lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable filtration system operation to support uninterrupted use of M313C/M313D/M315C wheel loaders.

The 208-60-71330 Solenoid Valve Assembly is an original quality hydraulic control component, specially designed for Komatsu PC400-7 and PC400LC-7 excavators (serial number 50001 and above). This valve plays a vital role in regulating hydraulic flow to various systems such as swing, travel, boom, arm, and breaker functions, based on electric input signals from the operator controls.

Built with high-temperature copper coils, reinforced casing, and precise valve mechanics, this solenoid valve guarantees stable performance, rapid response, and long service life in harsh working conditions. Manufactured by SPARKLING MACHINERY, it meets or exceeds OEM performance standards.
