Gearbox Reverse Engineering
Is your gearbox or gear component obsolete or out of commission? Need to find a replacement?
Don’t invest time and money into expensive new machinery. Gearbox reverse engineering can be a more reliable and affordable alternative.
.
What is Gearbox Reverse Engineering?
Reverse engineering breaks machinery, such as a gearbox, down into its individual components. That way, our engineering team can thoroughly evaluate and provide recommendations to meet your needs.
Our experts can recreate and manufacture original parts to OEM specifications, even from samples or drawings. We’ll restore your gearbox to like-new condition, ensuring the correct size, tolerance, and performance specifications are met.


Our Streamlined Reverse Engineering Process
- Submit Your Part: To get started, send us a spec, CAD drawing, or sample of the original component. Our team will take it from there.
- Inspection: Our highly skilled engineers will meticulously inspect the gearbox or part to determine the manufacturing requirements, ensuring nothing is overlooked.
- Scope & Estimate: We provide a detailed scope of work and an estimate that is not only affordable but also transparent, giving you peace of mind.
- Component Creation: Using your sample (or parts of it), we create replacement components and complete the necessary repairs.
- Easy Delivery: Our operations team ensures your rebuilt gearbox is delivered back to your facility.
We service all makes and models of gearboxes, even those with parts that are no longer commercially available. Ready to explore your options? Contact our technical team to schedule a call today.
