The High Pressure Oil Pump (HPOP) delivers high pressure oil to the fuel injectors, which operate hydraulically. To ensure superior performance, our Diesel High Pressure Oil Pumps are the product of an in-depth remanufacturing process that includes inspection, tear down and validation, cleaning, reassembly, and testing.

We disassembled and inspected diesel high pressure oil pumps from the competition. Here’s what we found:
All BWD® Diesel High Pressure Oil Pumps are the product of an exhaustive remanufacturing process at our TS16949, ISO9001, and ISO14001 certified facility. Throughout our process, our pumps and components are inspected, torn down and validated, cleaned, reassembled, and tested, so you can install our part with confidence. Take the process for our 37506, for example:
We perform a 100% inspection on all camshaft followers and replace them with new wherever required.
We inspect and clean each drive gear before reusing.
We install 100% new, updated high-pressure discharge fittings and torque them to factory specifications and the correct orientation to prevent leakage.
We perform a 100% inspection of both front and rear bearings. If the core bearings are bad, we replace them with 100% new bearings that are the product of a line boring/honing process.
We reassemble every check valve assembly with new sleeves, plugs, check springs, and machine-lapped flangers and plates.
We paint the exposed topside of the pump to prevent rusting. We don't paint the rest of the housing to prevent exposing the engine oil to paint contamination.
