Diesel Fuel Pumps

Diesel Fuel PumpsDiesel Fuel PumpsJasper Engines and Transmissions offers a wide selection of diesel fuel pumps including the Bosch Rexroth and the Shepard high pressure oil pumps, the Stanadyne DS and DB2, along with a variety of Caterpillar applications like the V-style pump for the CAT 3208 and the pump/governor for the Cat 3116. Fuel pumps are remanufactured in a climate-controlled, electronically filtered environment. As a Service Dealer for both Bosch and Stanadyne, JASPER’s Diesel Air and Fuel Component Division employs Associates that have been trained in original equipment specifications and processes.

JASPER® also focuses on processes that are specific to pump manufacturer, design and application. For example:

High-pressure Oil Pumps for 6.0L, 444, 466E and 3126 applications:

  • Custom sized O-rings installed to prevent leaks from the rear end sealing plate
  • 100% of the O-rings within the pump are replaced, along with all discharge fittings
  • Installation of a set screw through the housing stops the swash plate from turning and   prevents pressure and flow loss
  • The rotor thrust washer, a key wear item, is replaced and lapped to match the rotor in order to prevent cross leakage
  • 6.0L and 466E pumps receive a new bolt and friction washer on the drive gear
  • Testing with inspections for pressure, flow and leaks using a custom built test stand and software

Stanadyne DS pump for GM 6.5TE engines

  • 100% NEW PMD
  • 100% NEW transfer pump blades

Every fuel injection pump is thoroughly tested and precisely calibrated with computer-aided test equipment for consistent quality and performance. All Bosch injection pumps are calibrated on a state of the art Bosch 815 calibration stand. HEUI high pressure oil pumps are tested on a custom-built test stand to provide a live simulation of in-the-vehicle operation.
