Flender Gearbox Repair and Rebuild Services

A Flender gearbox rebuild can include complete disassembly, cleaning, inspection, identification of worn or failed components, component reconditioning or replacement, precision machining, reassembly, lubrication, and performance testing. The exact scope is established after inspection and failure analysis so the repair addresses the equipment’s actual condition and the requirements of its operating application.

Inspection involves evaluating the gearbox’s gears, shafts, bearings, housings, seals, lubrication-related components, and other internal parts. The findings help identify the failure mechanism and determine which components should be repaired, reconditioned, replaced, reverse-engineered, or manufactured. A service report can document the observed condition, recommended repairs, replacement parts, and proposed scope of work.

Components are inspected and evaluated to determine whether restoration is appropriate. Depending on their condition, gears, shafts, housings, and related parts may be repaired, refurbished, machined, or otherwise reconditioned rather than automatically replaced. This approach can help extend equipment service life while creating a repair scope based on the actual condition of the components.

Yes. Performance testing and quality verification form part of the gearbox repair process after reassembly. Testing helps verify that the rebuilt equipment is functioning properly and operating at the expected performance level before it is returned to service. The final testing approach is selected according to the repaired equipment and the completed work scope.
