Repairing EV Reduction Gearboxes Instead of Replacing Them
Schaeffler is addressing a new EV repair opportunity with its E-Axle repair systems, including RepSystem-G for reduction gearboxes. Electric cars do not use a conventional multi-speed transmission, but they still rely on a reduction gearset and differential to convert very high motor speed into usable wheel speed and torque.
How Schaeffler RepSystem-G Supports Workshops
High rotational speeds place substantial demands on bearings, and wear can eventually produce noticeable running or grinding noise. The Parts & Service News technical report follows the repair of a reducer and shows that bearings, seals and related components can be renewed rather than replacing an entire e-drive assembly.
A New Specialist Repair Opportunity for the IAM
The work requires correct pullers, measuring equipment, cleanliness and accurate bearing adjustment. The article also stresses the value of specialist training because errors during pressing, measurement or assembly can damage expensive components that may not be available separately. For workshops, this creates a potential EV specialisation with higher technical value than routine maintenance.
