Supplier bankrupt or part no longer available? Here is how to reproduce a machine component without a drawing.
The machine is at a standstill. The wear part you need no longer exists. The supplier is bankrupt, the manufacturer discontinued the model, or the drawing disappeared decades ago. You have only the defective part in your hands — and production waiting.
A defective part is not a dead end
Anyone who thinks that a machine component is irreplaceable without a drawing underestimates what accurate measurement makes possible. A well-executed reverse engineeringprocess does not start from a CAD file or a dimension table — it starts from the physical part itself.
That component contains all the necessary information: the geometry, the tolerances, the material, and the surface finish. The art lies in correctly reading that information and translating it into a reproducible production process.
It is skilled work. Not a stopgap measure.
This is how reproducing a part works in practice
Reverse engineering at BO-Solutions always begins with a thorough analysis of the supplied part. We look at wear, the function of the part in the machine, and what is measurable on the defective piece.
What is and is not reproducible
Not every part lends itself equally well to reverse engineering. The rule of thumb: if it can be manufactured, it can also be measured and reproduced. Bearings, shafts, gears, linings, couplings, blades, sliding components, hydraulic parts, housings, frames, and guides — all feasible. Anything with a clear mechanical function in metal or plastic.
Parts with integrated electronic components or special coatings require additional analysis. Molded parts with internal geometry that is not visible or measurable without destructive analysis are outside the scope — unless the customer agrees to a prototype laid out for inspection.
We always tell you honestly what is feasible before production starts.
The reproduced part is at least as good as the original
A question we receive regularly: is the reproduced part just as good as the original?
In most cases: yes — and sometimes better. Original suppliers, especially for older machines, worked with materials and processes that have since been improved. At BO-Solutions , we select the material based on the required function, not on what was available at the time. A wear part made of an improved steel grade or with a harder surface treatment performs better in practice than the original.
What we never do: make assumptions. Every reproduction is measured and documented.
Three situations where reverse engineering is the fastest solution
A machine unexpectedly comes to a standstill due to a defective part that is no longer available. Every day of downtime costs money. In that case, speed is the priority — we complete the measurement process and production together as efficiently as possible.
An installation is old enough that the original manufacturer no longer exists or provides support. Companies with machines that are ten, twenty, or thirty years old are familiar with this problem. With a reproduced part and a CAD model that we preserve, you rebuild a bill of materials.
You want to improve or modify a proven part — better materials, different tolerances, slight geometry change. Reverse engineering is the starting point for redesign.
Reverse engineering as a starting point for improvement
Reproduction is not always the end goal. Customers frequently start with an existing part that functions—but could be improved. It wears out too quickly, breaks at a specific spot, no longer fits in a new context, or the tolerances are too wide for current quality requirements.
Reverse engineering then lays the foundation: we measure the existing part, create a CAD model, and analyze where the weakness lies. Next, we adjust the design — better steel grade, different geometry, tighter tolerances, modified surface finish. The result is not a copy, but an improved version of something that has already been proven in practice.
That combination of surveying, analyzing, and improving is precisely where BO-Solutions contributes its expertise. Not just executing what is requested, but asking the question the client sometimes doesn't ask themselves: can this be done better?
From Roeselare for the entire Belgian and European manufacturing industry
BO-Solutions is based in Roeselare (West Flanders) and provides reverse engineeringservices to clients throughout Belgium and adjacent regions: from West Flanders to Brussels, Antwerp, Liège, and the border regions with the Netherlands and France.
Urgent orders are possible. Anyone bringing in a defective part can, in most cases, count on an initial analysis and concrete feedback within the day.
The question you don't ask costs you more than reproduction
Many companies wait too long. They search for an original supplier for months, accept a machine running at half capacity, or buy a completely new installation — when all they needed was a new part.
Reverse engineering is not a last resort. It is a professional service that can be used considerably more often in practice than most buyers assume.

Frequently asked questions about reproducing parts without a drawing
What do I need to get started?
The defective or worn part itself. No drawing, no dimension chart, no reference number required. The more context you can provide about the machine and the function of the part, the faster we can work — but it is not a requirement.
How long does the process take?
From measurement to delivered part: depending on the complexity, typically between three days and three weeks. Expedited processes are possible for production standstill. Contact us for a concrete estimate.
What if the part is too worn to measure?
We then analyze what is still measurable and reconstruct the rest based on the function and the machine. In some cases, we request a second unit — even a worn one — as a reference. We always tell you honestly what is feasible.
Do you also make small quantities?
Yes. One piece is no problem. Anyone wishing to build up a small stock of critical parts can include it with the first order—that saves setup costs in the long run.
How much does it cost to reproduce a part?
The price depends on the complexity and the time required for the measurement process. A simple turned part starts at a few hundred euros. More complex pieces with multiple machining operations and tight tolerances are higher. We always provide a quotation before production starts.
Can I take the CAD model with me as well?
Yes. The model we create is the property of the customer. You can use it for future reorders — even with other suppliers.
