The oil distribution cover (Part No. 86746941) is a precision-engineered critical component exclusively designed for hydraulic rock drills—the core equipment in mining, quarrying, and construction rock fragmentation operations. Moreover, we engineer it to meet the rigorous demands of high-pressure hydraulic systems, so this oil distribution cover plays a non-negotiable role in regulating oil flow, maintaining pressure stability, and preventing leakage in hydraulic rock drill power units.
We craft our 86746941 oil distribution cover from high-strength, corrosion-resistant alloy materials, so it withstands extreme working conditions—including heavy vibration, high temperature, and abrasive dust common in mining sites. Additionally, we precision-machine its sealing surfaces to ensure a tight fit with hydraulic drill components, thus eliminating oil seepage that can lead to equipment downtime and increased maintenance costs. Furthermore, the robust material composition also extends the component’s service life, which in turn reduces the frequency of replacements for mining and quarrying operations that rely on continuous equipment uptime.
This replacement oil distribution cover works with a wide range of hydraulic rock drill models and serves as a direct OEM-grade substitute. As a result, it ensures seamless installation without modifications, even for operators with limited technical expertise in hydraulic system maintenance. Whether you’re maintaining surface rock drills for quarrying or underground hydraulic drills for mining tunneling, the 86746941 oil distribution cover delivers reliable performance. In addition, it extends equipment service life and reduces operational interruptions that can cut into project deadlines and profitability. Also, we design it to match the exact specifications of original parts, therefore eliminating the risk of mismatched components that can compromise hydraulic system efficiency and lead to costly repairs.
We prioritize strict quality control throughout the manufacturing process, starting from raw material selection and progressing to final precision testing. Consequently, each oil distribution cover meets or exceeds industry standards for hydraulic rock drill components. Besides, we subject every unit to pressure leakage testing and dimensional accuracy checks, so we can guarantee optimal performance in high-stress hydraulic systems that operate around the clock in harsh mining environments. For mining contractors, equipment maintenance teams, and spare parts distributors, this component is a cost-effective solution. Finally, it is a proven way to keep hydraulic rock drills running at peak efficiency and minimize unplanned downtime.
