The 0445020247 is a genuine Bosch CP2.2 series high-pressure common rail fuel pump. It carries the primary Weichai OEM factory part number 612630030024. This unit is engineered specifically for Weichai WP12 (11.6L / 12L) Euro 4 and Euro 5 common rail diesel engines, widely installed in heavy-duty commercial vehicles including Shacman X3000, Shacman F3000, FAW J6, and Zoomlion crane platforms.
This 0445020213/247/245 pump utilizes a heavy-duty twin-plunger CP2.2 configuration with a gear-driven shaft and an attached rear mechanical fuel feed pump. Regulated by an ECM-controlled fuel metering unit, the assembly delivers sustained fuel gallery pressure up to 1600 bar to the common rail log on Weichai WP12 blocks.
Wear on the CP2.2 internal roller tappets, plungers, or gear feed pump clearances drops high-pressure delivery during heavy hauling. On Weichai WISE15 and Bosch EDC17 ECUs, this failure triggers active fuel rail pressure deviation codes, causing engine power derate and long hot-crank cycles. Replacing the worn unit with this new 0445020213/247/245 (Weichai 612630030024) pump restores factory rail pressure and fuel delivery.
