The Challenge
A major food processing manufacturer faced a challenging situation when a critical gearbox arrived at DESCH in a completely disassembled condition. The unit arrived in pieces, creating uncertainty around its condition, the extent of required repairs, and whether it could be successfully restored to service.
To determine the condition of the gearbox and identify the necessary corrective actions, DESCH performed a comprehensive quality inspection using advanced Coordinate Measuring Machine (CMM) technology and 3D scanning. The inspection revealed that critical housing bores were out of alignment, creating a risk to gearbox performance, reliability, and long-term service life.
Without corrective action, the gearbox would not be able to operate within the required tolerances, increasing the potential for premature component wear and costly production interruptions.
The Solution
DESCH developed a complete recovery plan to restore the gearbox to OEM-quality operating standards.
The project included:
- Detailed inspection using CMM measurement and 3D scanning technology.
- Identification of housing bore misalignment and dimensional issues.
- Precision repair of the gearbox housing to restore critical bore geometry.
- Reinspection and quality verification following housing repairs.
- Assembly of the gearbox using a new set of replacement gears.
- Complete rebuild performed by the DESCH Canada team.
- Functional testing to verify performance and reliability.
- Final repainting and preparation for return to service.
Throughout the process, DESCH maintained strict quality controls to ensure all repairs met the required specifications before the gearbox was approved for testing.
The Result
Following housing restoration, assembly, and testing, the gearbox successfully completed performance verification and was returned to the customer as a fully rebuilt unit.
The repair transformed a gearbox that arrived as a collection of disassembled components into a fully functioning asset ready for operation.
As an added measure of confidence, representatives from the customer visited the DESCH facility during testing to witness the rebuild process and performance verification firsthand.
Key Outcomes
Successfully recovered a gearbox received in a fully disassembled condition.
Identified critical alignment issues using CMM inspection and 3D scanning.
Restored housing geometry through precision machining and repair.
Installed new replacement gearing.
Completed full assembly, testing, and quality verification.
Returned the gearbox to reliable operating condition.
Earned customer confidence through transparent testing and inspection processes.
Customer Impact
For large industrial operations, gearbox failures can create significant production risks and maintenance costs. When critical equipment requires extensive restoration, customers need confidence that repairs are completed accurately and that the asset will perform reliably in service.
DESCH’s engineering expertise, advanced inspection capabilities, and comprehensive repair services provided the customer with a clear path forward. Rather than replacing the gearbox or accepting uncertainty regarding its condition, the customer received a fully restored unit that had been thoroughly inspected, rebuilt, and tested.
The successful project reinforced the value of working with a repair partner capable of managing every stage of the process from advanced metrology and housing restoration to assembly, testing, and final validation.
When critical equipment requires more than a standard repair, DESCH delivers the engineering expertise and quality assurance needed to restore confidence and reliability.
