Purpose of the Part

The 0402996316 controls the amount and timing of high-pressure diesel fuel delivered to the engine. On the QST30 configuration documented for this pump, it operates as one of two injection pumps, with 3093637 serving the right side and a separate pump serving the left side.

Issue Symptoms / When to Replace

Injection-pump problems can cause hard starting, uneven running, loss of power, excessive smoke, unstable engine speed, or cylinders that are not receiving the correct amount of fuel. Because restricted fuel supply, injector problems, governor/control faults, or contaminated fuel can create similar symptoms, the complete fuel system should be diagnosed before replacing the pump.

Brand Information

Bosch has manufactured diesel injection equipment since 1927, when it began series production of diesel injection pumps for commercial-vehicle engines. In-line injection pumps became a major part of Bosch heavy-duty diesel technology, and Bosch continued developing fuel-metering systems for commercial and industrial diesel engines for decades afterward.

Installation Notes

This pump must be installed and timed according to the QST30-specific Cummins/Bosch procedure. Keep the fuel system clean during installation and verify the pump position before removal, because the documented QST30 system uses different right- and left-side pump assemblies.

How to Identify an OEM Part

A genuine unit can be identified by the Bosch factory identification plate showing Bosch number 0 402 996 316. Genuine examples are also documented with the Bosch pump identification PES6P130A720/3RS8529 and Cummins number 3093637 on the pump identification data.
