Planning a Gearbox Rebuild for Paper Mills

A rising temperature or a new vibration gives a mill maintenance team a reason to investigate a gearbox. Recording when it started, and under what load, gives the rebuild team context for the damage they find. Overton Chicago Gear’s guide follows that record through inspection, repair choices and testing for paper and pulp mills. Shafts, bearing seats, seals and housing bores need attention alongside the gear teeth. The measurements help determine which components remain serviceable and which need restoration or replacement. OCG supports the industry with gearbox rebuilds, customized gearing and reverse engineering for critical spares. Bring available drawings and operating history into that discussion, especially for a drive with limited documentation. Before accepting the rebuild, agree on the checks and testing included in the scope. Keep those findings with the installation record so your team has a reference when monitoring the unit after it goes back into mill service.
