SPM-HEP-5140 is the VE type distributor injection pump with the drive gear fitted: cast alloy body with the boost compensator, the fuel shutoff solenoid and leads, green sensor connector, four capped delivery valves and the timing gear on the drive shaft. It is used on Isuzu 4JB1-TC 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 Zexel 104646-5113 and Zexel 104746-5113.
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 Zexel 104646-5113 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.
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.
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.
No. It is an aftermarket fuel injection pump made to replace the Zexel 104646-5113. It is not made by the original manufacturer; the number only shows what it replaces.
