Drive units with separately included breather valve
Mounting position M3
For the use of drive units in mounting position M3 you are not permitted to mount the enclosed breather valve on the drive unit.
For drive units in mounting position M3, only use the variant with integrated pressure compensation (/PG option). In doing so, observe the addendum "MOVIGEAR® drive unit type MGF..-..-C – "Wet-area design /WA" and "Integrated pressure compensation in the gear unit /PG" options".
The MGF..1-DSM-C drive unit can be operated in M3 mounting position without breather valve and without any restrictions. The option "/PG" is not available for this size.
Mounting positions M1, M2, M4, M5, M6
SEW‑EURODRIVE delivers drive units ordered for universal operation in mounting position M1, M2, M4, M5, M6 with an enclosed breather valve.
In this case, the breather valve is delivered in the hollow shaft of the drive unit. Before startup, replace the highest oil screw plug with the provided breather valve.
Tightening torque
Tighten the breather valve included in the delivery from SEW‑EURODRIVE with 8.0 Nm.
The position of the breather valve depends on the mounting position being used. Observe chapter Mounting positions.
