Zumbrota’s remanufacturing process includes inspections before, during, and after the rebuild. The case is checked for cracks and excessive wear, and component parts are inspected against OEM specifications. Internal parts receive a full inspection, including gear-wear checks, main-shaft straightness testing, and synchronizer testing.
Seals, bearings, and other common wear components are replaced. The housing and top cover are cleaned using a hydro-blasting and rinsing process intended to restore the OEM finish. The transmission is inspected throughout remanufacturing to check that it meets Zumbrota’s build standards.
