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 Deutz TD2.9, and 1 more listed under compatible equipment. Check the old fuel injection pump is marked 04132378 or one of the cross references, because makers change parts between serial ranges.
On the Deutz TD2.9, 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.
Yes. Fill the pump and its suction line with clean fluid before the first start. Running it dry, even for a few seconds, can score it.
No. It is an aftermarket fuel injection pump made to replace the Deutz 04132378. It is not made by the original manufacturer; the number only shows what it replaces.
