Precision Reverse Engineering for Gears and Power Transmission Components
No OEM prints? No problem.
At Dayton Gear & Tool, we specialize in reverse engineering worn, damaged, and obsolete gears and mechanical components when original drawings and specifications are unavailable. Using advanced inspection technology and decades of manufacturing experience, we accurately reproduce gears, splines, shafts, and other critical power transmission components.
Advanced Gear Inspection & Analysis
At the heart of our reverse engineering process is our state-of-the-art KAPP NILES Gear Inspection Machine. This advanced gear checker allows us to capture precise gear geometry and critical inspection data, including:
- Involute profile measurement
- Lead and helix analysis
- Pitch inspection
- Runout verification
- Tooth thickness measurement
- Gear quality evaluation
- AGMA compliance verification
By combining this detailed inspection data with advanced CAD modeling, our engineering team can generate accurate 2D drawings and 3D models for manufacturing replacement components that meet or exceed original specifications.

More Than Just Replication
In addition to reproducing existing parts, we can evaluate failed or worn components and recommend design improvements to increase strength, reliability, and service life. Our team frequently helps customers upgrade obsolete designs and improve manufacturability while maintaining form, fit, and function.
