SPM-HEP-5117 is the Bosch VP44 type radial piston distributor pump: alloy body with the electronic control unit and its plug on top, four capped high pressure outlets, the drive hub with a splined shaft and the fuel inlet and return fittings. It is used on Nissan Navara D22 / NP300 YD25 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
It replaces Bosch 0470504033, Bosch 16700-VK500 and Bosch 16700-VK50A.
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 Nissan Navara D22, and 1 more listed under compatible equipment. Check the old fuel injection pump is marked 0470504033 or one of the cross references, because makers change parts between serial ranges.
On the Nissan Navara D22, 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.
On piston pumps, yes. Fill the case through the drain port with clean hydraulic oil before the first start, or the bearings run dry.
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 Bosch 0470504033. It is not made by the original manufacturer; the number only shows what it replaces.
