Electric motor refurbishment for Mercedes e-Sprinter – a cheaper alternative to authorized service
Defective electric motors in the Mercedes e-Sprinter are often classified by authorized service centers (ASO) as suitable only for replacement. Unfortunately, the cost of such an operation is very high. We offer a more effective and much more affordable alternative – complete electric motor refurbishment.
Thanks to our specialist knowledge and experience, we are able to restore the full efficiency of the drive unit, even though its design is complex and based on modern technologies.
In the case of the motor with part number A 910 340 25, the most common issue is improper heat dissipation. This leads to bearing damage and coolant leaking into the stator, which in turn causes winding failure.
Factory defect of the motor: cause and solution
Mercedes e-Sprinter – bearing seal failure and an effective repair method
After analyzing multiple cases of failures in the Mercedes e-Sprinter equipped with the electric motor part no. A 910 340 25, we were able to precisely identify the main cause of the problem. It is a leaking bearing seal, which allows coolant to penetrate the inside of the unit.
Why is this so dangerous?
The failure may occur at different stages of coolant intrusion.
In the initial phase, the vehicle often can still be started, but the damage may continue to progress.
The most serious consequences include: damage to the high-voltage winding, insulation breakdown on cables, and even inverter burnout.
The cost of replacing the entire motor at an authorized service center is extremely high.
Our solution
We have developed our own method of refurbishing and eliminating this defect. This enables an effective repair without the need to replace the entire drive unit. As a result, it is possible to save tens of thousands of zlotys and significantly reduce the vehicle’s downtime.
