Bosch 610800080072 is the Bosch CP3 type common rail pump: a cast body with flat mounting face, a keyed drive shaft with nut, the metering unit with its plug and capped high pressure outlets. It is used on Weichai WP7 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
The same part is also sold as Weichai 0445020142.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Hard starting and low power
A worn injection pump delivers less fuel at lower pressure: long cranking and weak power under load.
Smoke and uneven running
Uneven delivery between cylinders shows as smoke and rough running.
Fuel leaks
Leaks from the pump body or shaft seal mean it is time to replace it.
Fitting tips
Set the pump timing to the engine maker's figure, bleed the fuel system, and use clean fuel and new filters.

Yes, it is a direct replacement for the Weichai 610800080072 with the same fitting.
Often 5,000 to 10,000 hours with clean fluid, much less with dirt or air in the system. It is usually changed on condition, not by hours.
Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.
Most failures come from contamination, cavitation from a restricted inlet, or running low on fluid. Check the inlet and the fluid before fitting the new fuel injection pump.
Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
No. It is an aftermarket fuel injection pump made to replace the Weichai 610800080072. It is not made by the original manufacturer; the number only shows what it replaces.
