Reverse Engineering
When original engineering drawings or replacement components are unavailable, reverse engineering provides a practical path to manufacturing functional replacements. PSI Hydraulics evaluates existing hydraulic components and assemblies to reproduce the dimensional and functional characteristics required for continued equipment operation.

Overview
Reverse engineering is the process of analyzing an existing component or assembly to develop the manufacturing information required to reproduce it. The objective extends beyond measuring external dimensions. Successful reverse engineering identifies the critical geometric relationships, functional interfaces, material characteristics, and manufacturing features that allow a replacement component to perform within the original hydraulic system.
PSI Hydraulics provides reverse engineering services for hydraulic cylinders, hydraulic components, OEM equipment, and legacy industrial machinery. Projects frequently involve obsolete components, discontinued replacement parts, damaged assemblies, or equipment where original engineering documentation is no longer available. Existing components are evaluated to determine the dimensions and functional characteristics that influence fit, sealing performance, load transfer, and overall hydraulic operation.
Because wear, deformation, or previous repairs may alter the condition of an existing part, reverse engineering often requires distinguishing between original design intent and service-related damage. Inspection, dimensional verification, and engineering evaluation help identify the features that should be reproduced during manufacturing rather than simply duplicating the condition of a worn component.
The result is manufacturing documentation and production methods that support reliable replacement components while maintaining compatibility with the original equipment.

Why Choose PSI
Effective reverse engineering requires understanding how a component functions within the complete hydraulic assembly rather than simply recording dimensions. Manufacturing a successful replacement often depends on identifying the features that influence sealing performance, alignment, load transfer, pressure containment, and compatibility with surrounding components.
PSI Hydraulics approaches reverse engineering as an engineering and manufacturing process rather than a measurement exercise. Existing components are evaluated to distinguish critical functional geometry from wear or service-related damage, allowing replacement parts to be manufactured with the dimensional integrity necessary for reliable operation. This process supports continued operation of equipment when OEM documentation or replacement components are no longer available.

Frequently Asked Questions
Can reverse engineering be performed without original engineering drawings?
Yes. Reverse engineering is specifically intended for situations where drawings, CAD models, or manufacturing documentation are unavailable. Existing components often provide the information needed to evaluate the design.
How do you account for wear on an existing hydraulic component?
Wear patterns, deformation, corrosion, and previous repairs are evaluated during inspection to distinguish service-related changes from the original manufactured geometry. This helps prevent worn dimensions from being reproduced in the replacement component.
Can reverse engineering reproduce obsolete OEM hydraulic components?
In many cases, yes. Existing parts can often be evaluated and manufactured when original replacement components are no longer available from the OEM.
Which dimensions are considered most critical during reverse engineering?
Critical dimensions vary by component but commonly include sealing interfaces, bearing fits, concentricity, thread geometry, mounting features, and relationships between mating surfaces that affect hydraulic performance.
Does reverse engineering include manufacturing replacement components?
Yes. Once the engineering evaluation is complete, the resulting manufacturing information can be used to produce prototype or production replacement components, depending on project requirements.
What should be submitted for a reverse engineering project?
An existing component or assembly is typically the best starting point. Supporting information such as photographs, operating conditions, material specifications, application details, and any available documentation can further assist the evaluation process.
