Reverse engineering • replacement gears • obsolete parts

Engineering the replacement parts you can't buy.

Precision Reverse turns worn, obsolete and undocumented components into production-ready engineering data and finished replacement parts.

Built around the part you need — not the machines we happen to own.

Some jobs begin with a worn sample. Others begin with a drawing or CAD model. Precision Reverse can support the engineering only, coordinate the manufacture, or supply the finished replacement component.

01

Reverse Engineering Services

Physical components can be measured and reconstructed into usable 3D CAD models and manufacturing drawings. The aim is to recover functional geometry, fits, interfaces and critical features — not simply copy wear or damage.

Worn parts • broken samples • mating components • legacy prints
02

Obsolete Replacement Parts

When the OEM no longer supports the equipment, existing parts and documentation can still provide enough information to create a practical replacement and keep machinery, vehicles and legacy equipment in service.

Gears • shafts • splines • couplings • machined components
03

Custom & Replacement Gears

Gear projects are supported by practical gear-industry and manufacturing-engineering experience. Work can include bevel, spur and helical gears, splined components, prototypes and low-volume replacement quantities.

Manufacturing & Sourcing

If you already have a drawing or model, Precision Reverse can coordinate turning, milling, gear cutting, broaching, heat treatment, grinding and inspection through suitable specialist suppliers.

From part to production

Engineering first. Manufacturing follows.

A successful replacement part starts with understanding how the original component functions, how it mates with the surrounding assembly and how it can realistically be manufactured today.

1
EvaluateReview the component, drawings, application and quantity required.
2
Measure & EngineerRecover geometry, create CAD data and develop a manufacturing drawing where needed.
3
ManufactureCoordinate appropriate processes and specialist vendors for the job.
4
Inspect & DeliverConfirm the finished component meets the agreed requirements before shipment.
Recent bevel gear project

Existing gear. New replacement. Real manufacturing.

A recent UK project illustrates the type of low-volume replacement work Precision Reverse is built around: existing gear geometry, newly machined components and specialist gear cutting brought together to create practical replacement parts.

Customer and application details can remain confidential. The point is simple: these are genuine engineering and manufacturing photographs, not stock imagery.

Old drawings still matter.

Existing prints, samples and mating parts can all contribute useful information when an OEM part is no longer available.

Capabilities

Lean by design. Broad in capability.

Precision Reverse is structured around engineering knowledge, practical sourcing and trusted specialist suppliers rather than unnecessary fixed overhead.
