Once disassembled, each component is thoroughly inspected for wear, pitting, scoring, cracking, or other forms of damage. Bearings, shafts, gears, seals, and housings are all evaluated against original specifications. Our team documents every finding to create an accurate repair plan and ensure all issues are addressed during the refurbishment process.

Components undergo a thorough cleaning process to remove grease, debris, corrosion, oxidation, and any contaminants that could interfere with refurbishment. Proper cleaning is essential for accurate inspection, quality repairs, and strong bond surfaces for any coatings or welds. Our team uses industrial cleaning methods appropriate to each component type.

Repairable components are restored using specialized refurbishment techniques, including machining, grinding, welding, and thermal spray coatings where applicable. Our in-house machine shop capabilities allow us to rebuild worn surfaces, restore critical dimensions, and return components to like-new tolerances — reducing the need for costly new parts.

After the refurbishment is complete, the gearbox is carefully reassembled using restored and replacement components. All bearings, seals, and hardware are replaced as a standard part of the refurbishment process. Assembly is performed to manufacturer specifications, with attention to proper fits, clearances, and torque values throughout.

The rebuilt gearbox undergoes final quality checks to verify it meets all required specifications before being returned to service. A standard gearbox refurbishment can take 4–6 weeks depending on part availability and the extent of repairs needed — though expedited turnaround is available for emergency situations. Churon provides a full rebuild report along with each completed unit.
