Delphi 2644H042 is the Delphi DP210 type rotary injection pump: alloy and dark cast body with the mounting flange, four delivery outlets, the advance unit, throttle lever with return spring, fuel shutoff solenoid and a keyed drive shaft. It is used on Perkins 1104C-44TA 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 Delphi 9320A536G, Perkins 9320A530G and Caterpillar 483-2353.
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 was made for the Perkins 1104C-44TA, and 2 more listed under compatible equipment. Check the old fuel injection pump is marked 2644H042 or one of the cross references, because makers change parts between serial ranges.
On the Perkins 1104C-44TA, 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 Perkins 2644H042. It is not made by the original manufacturer; the number only shows what it replaces.
