Reverse Engineering Obsolete & Discontinued Parts

The OEM stopped making it. The supplier is gone. We reproduce obsolete and discontinued parts from your sample, the mating assembly, or any documentation that survives — and often improve on the original.

Why Obsolete Parts Are the Hardest — and Why We Do It

When a part goes obsolete, every failure becomes a crisis. There is no part on a shelf, no OEM to call, no cross-reference to a current equivalent. The machine sits idle and the cost accumulates by the hour. Customers come to us specifically because the normal supply chain has no answer.

We reproduce obsolete parts regularly. The process is direct: measure what survives, reconstruct what doesn't, confirm the geometry with you, manufacture, and ship.

When No Original Part Survives

The most difficult scenario is when there is nothing left to measure — the part failed completely and was discarded, or was never retained. We work through this systematically:

  • Mating parts — the bore it sat in, the shaft it drove, the housing it sealed against. From these we derive the missing dimensions.
  • Exploded diagrams and spare-parts manuals — older equipment often has parts books with proportional diagrams. We use these scaled to known reference dimensions.
  • Similar models — the same machine in a later variant may have updated but compatible parts. We use these as a baseline and adjust.
  • Failed fragments — even heavily broken parts carry geometry: cross-sectional profiles, bore positions, wall thickness, thread starts.

Should You Upgrade When Reproducing?

Make spares while you're at it. Once we have the CAD for a previously obsolete part, making 2–3 spares from the same setup costs a fraction of the first piece. It means the next failure doesn't put you back to square one. We recommend it for every obsolete part job.

Process

01

Tell us the situation

What failed, what equipment it came from, what you still have — part, photos, mating assembly, manual pages. We assess the best reconstruction route.

02

We gather all evidence

Measurement of the sample or mating parts, photograph analysis, manual interpretation. All sources are used and cross-checked.

03

Reconstruct — noting all assumptions

CAD model built. Every dimension derived from inference (not direct measurement) is flagged in the drawing for your review. Nothing is hidden.

04

You confirm

Review the drawing. Correct any inferences you recognise from knowledge of the machine. Specify upgrades if desired. We revise and confirm before cutting.

05

Manufacture, inspect, ship

Part made, inspected to the approved drawing, shipped with inspection report and CAD file. Spares from the same run at marginal cost.

Frequently Asked Questions

+

Yes. We reproduce the part from your sample, from mating components, from old manual diagrams, or from whatever remains. We do not need the original manufacturer's cooperation, drawings or tooling.

+

We work from the components the part interfaces with — the bore it sat in, the shaft it drove, the housing it sealed. Dimensions are derived indirectly and confirmed against the assembly before we manufacture. This works for a surprising proportion of lost originals.

+

Often worth considering. If the original failed in a predictable way — wear on a specific surface, corrosion in a particular area, cracking at a stress concentration — we can address it in the reproduction. Switching from cast iron to ductile iron, plastic to bronze, or adding a hard-chrome surface are common upgrades at negligible extra cost.

+

One piece. There is no minimum order on machined parts. We recommend making 2–3 spares from the same setup so the next failure doesn't put you back to square one, but one is a perfectly valid order.
