Weichai WPB612640110124 Turbocharger Oil Feed Line Assembly

The WPB612640110124 turbocharger oil feed line is a critical component within the engine lubrication system, designed to deliver pressurized engine oil to the turbocharger bearing cartridge. Manufactured to Weichai OEM specifications, this assembly typically consists of a high-temperature resistant steel tube or reinforced braided hose configuration with precision-formed banjo or flange end fittings. It is engineered to withstand the high thermal cycles and pressure pulses inherent in heavy-duty diesel turbocharging systems. The line routing and fitting geometry are calibrated for direct installation on Weichai WP10, WP12, and WD12 series engine blocks without modification. The component includes necessary sealing surfaces compatible with copper or aluminum crush washers to prevent leakage under operating pressures up to 3.0 MPa. This part serves as a direct replacement for the original equipment line, restoring the integrity of the turbocharger lubrication circuit. Regular inspection and replacement are recommended during major overhauls or turbocharger replacement to mitigate the risk of oil starvation and subsequent bearing failure.
