Who rebuilds the VP44 pump and what parts are replaced?

We are a Bosch Authorized Four-Star rebuilder and have trained technicians who rebuild the pumps at our Bolingbrook, IL location. All of the electronics, the housing, and the piston are replaced as well as any other parts that are damaged or show signs of wear.

Here At The Diesel Store, Our Quality Control Process Starts The Minute We Receive A VP44 Fuel Injection Pump Core.

1. Our incoming department inspects the pump for contamination, seizure or evidence of tampering.
2. The VP pumps are then cap plugged, washed with a recyclable solvent and then washed a second time in an environmentally friendly hot water solution in accordance with our ISO14001 Environmental Management System.
3. Each VP44 pump is then disassembled individually to ensure that the parts that came in with the pump go back with the same pump.
4. After disassembly, the internal parts are cleaned and the external parts are buffed and polished for a like-new appearance.
5. The disassembled pump is then boxed and moved into our assembly room.
6. There, our Factory Trained Technicians meticulously inspect each part for even the slightest defect or wear. If there is a question, the part is discarded and replaced with new.
7. Each pump is then assembled by the same technician that performed the parts inspection. Our ISO9001 Quality Management System of continuous improvement ensures the highest quality pump as well as the most efficient program so that your costs are minimized.
8. The pump is then installed on the latest OE test equipment and the automated calibration process makes sure that the pump is error free.
9. The pump is then removed from the test bench and drained of all residual test fluid. Each pump receives protective caps to minimize leakage or contaminate ingress.
10. The VP44 pumps then receive their finishing kits with all of the necessary gaskets and o-rings for installation.
11. External screws are then re-torqued and seal painted to prevent tampering.
12. Each pump is boxed in specially designed packaging to eliminate the danger of damage during shipping.
