Each core pump is 100% torn down and each component carefully inspected for suitability to reuse. Imperfect parts are discarded. Approximately 1 in 5 core pumps are 100% rebuildable once fully processed. 80% of pumps require donor parts from inventory to complete to an acceptable standard. Broken springs, sheered retaining hardware, pitted ball bearings, seized solenoid and corroded sealing surfaces are extremely common reject causes.
After passing initial inspection all components, internal and external, aluminum, steel plastic and rubber are ultrasonically cleaned to remove the sludge encumbering the inner workings. The majority of deposits are removed at this point. Components are reinspected and those that do not clean up are discarded. An additional 20% of components are rejected at this stage in the process leaving only the finest parts suitable for safe reuse.
Aluminum bodies and components are vapor honed to a high quality surface finish that is both cosmetically pleasing and durable. The wet blasting peens and seals the surface to a luster approximating the appearance of fresh cast aluminum. These units are NOT painted. Steel parts are hand polished or vapor honed as applicable to ensure free and clean operation of moving internal parts critical to reliable operation.
All steel parts used in the pump subject to direct contact with the environment and visual appearance are chemically stripped of existing plating, machine polished to a high sheen and plated with yellow zinc chromate to replicate the original finish and appearance. The plating looks great and will serve to protect the steel from corrosion for years to come as the original plating did its best to since produced.
With a massive inventory of hand cleaned, polished, vapor honed and plated parts along with replacement seals each pump is built to exacting standards of perfection. Only the nicest components go into each rebuilt unit. With each pump you can be assured it will reliably perform day after day on your show car, daily driver, or SpecE30....and not to mention the cosmetic appearance that goes along with a selection process this detailed.
Once completed each pump is tested on the bench before being shrink wrapped for inventory or shipping. Coil winding impedance, motor inrush and operation amperage draw verified within anticipated spec. Solenoids cycled for validation, and finally the hydraulic system sealing is tested to 100psi holding pressure. Once tested to satisfaction plastic port plugs are installed and a replacement anti-tamper cap is pressed into place for security.
