When￿joining￿the￿transmission￿and￿the￿electrical￿machine￿the￿procedure￿described￿in￿the￿repair
instructions￿must￿be￿followed.￿Ensure￿axial￿alignment￿of￿the￿transmission￿input￿shaft￿and￿output￿shaft
to￿avoid￿distortion￿during￿assembly.￿In￿addition,￿the￿two￿gearings￿must￿be￿greased￿before￿joining.￿Do

There￿is￿a￿sealing￿ring￿at￿the￿joining￿connection￿between￿housings￿of￿the￿electrical￿machines￿and￿the
transmission,￿whose￿cross-section￿is￿shaped￿like￿the￿letter￿"X".￿This￿X-sealing￿ring￿must￿be￿replaced
before￿joining￿and￿is￿included￿in￿the￿delivery￿specification￿of￿the￿transmission.
The￿two￿connections￿for￿the￿coolant￿lines￿integrate￿the￿electrical￿machine￿in￿the￿cooling￿circuit￿of￿the
electric￿motor.￿This￿is￿described￿in￿the￿chapter￿"Cooling￿of￿electric￿motor￿components".
