Jasper Engines & Transmissions has acquired a Bosch EPS815 computerized pump tester for its diesel fuel pump department.
This test bench is the only approved system that allows JASPER to test the Bosch VP44, a six-cylinder rotary-style pump used on the 5.9L Cummins in mid-year 1998-2002 Dodge Ram pickups.
The VP44 is an electronically-controlled fuel pump that utilizes information shared by a fuel pump control module (FPCM), and an electronic control module (ECM) on the engine, to vary fueling and injection timing. The FPCM responds to input from the ECM by referring to fueling data and timing information stored in its memory and actuating the pump’s fueling and timing solenoids.
“With the Bosch EPS815, we can program the pump and gain access to any fault codes that may have been processed, such as a hard start or rough-running condition, while the pump was on the engine,” says Tom Padgett, JASPER Fuel Room Technician.
The total time a fuel pump spends on the tech bench is approximately three hours. “The first part of the test is to establish parameters within the bench’s computer software,” says Padgett. “After that, the bench automatically tests the pump, then prints out the results. The unit will not pass until it meets the set parameters within the system.”
The automated test bench allows the Associate to return to his work area and build additional pumps. “Our next step is to add a second computer monitor from the test bench to the assembly area so the associate can watch the test procedure while he builds pumps,” says JASPER Diesel Quality Captain TJ Abrams. “That way, if there is an error, the associate can see them at his work bench, then has the chance to come in to the test room and make necessary adjustments.”
The EPS815 has the capability to test the CP3 high pressure common rail pumps commonly found on the 6.7L Cummins used in late-model Dodge pickups. The EPS815 can also test conventional Bosch mechanical pumps.
