Possible failures/remedy
12/16
Failure Possible cause Remedy
Unusual noise in the area where the gear unit is mounted
Gear unit mounting has loosened Tighten retaining screws and nuts to the specified torque. Replace the damaged/defective retaining screws or nuts.
Operating temperature too high Too much oil Check the oil level, correct if necessary.
Oil too old Check when the oil was last changed; change the oil, if necessary.
The oil is heavily contaminated Analyze the oil to determine the cause; take measures, if necessary; change the oil.
Ambient temperature too high Protect the gear unit from external heat sources (e.g. provide shade).
Gear units with fan: Air intake opening/gear unit housing contaminated Check air intake openings, clean them if necessary; clean the gear unit housing.
For gear units with built-in cooling: Cooling liquid flow rate too low; cooling liquid temperature too high; deposits in cooling system
Check the cooling liquid flow rate; check the entry temperature of the cooling liquid, clean the cooling system.
Malfunction of the oil-air or oil-water cooling system Observe the separate operating instructions for the oil-water and oil-air cooling system.
Malfunction in the water cooling (water cooling cover, water cooling cartridge) Check the cooling water throughput and the entry temperature of the cooling water, clean the cooling system.
Temperature at bearing points too high
Not enough oil Check the oil level, correct if necessary.
Oil too old Check when the oil was last changed; change the oil, if necessary.
Bearing damaged Check the bearing and replace it if necessary. Contact SEW-EURODRIVE.
Oil leaking at the cover plate, gear unit cover or bearing cover
Seal broken at the cover plate, gear unit cover or bearing cover
Tighten the bolts on the respective cover. Observe the gear unit. Contact SEW-EURODRIVE if oil is still leaking.
Oil leaking from oil seal Too much oil Check the oil level; correct if necessary
Sealing lip of the oil seal turned up Vent the gear unit; monitor the gear unit. Contact SEW-EURODRIVE if oil is still leaking.
Oil seal damaged/worn Check oil seals; replace if necessary.
Oil leaking from gear unit breather Too much oil Check the oil level, correct if necessary.
Drive not installed in proper mounting position Install breather plug correctly and adjust the oil level.
Frequent cold starts (oil foams) and/or high oil level Install oil expansion tank.

Failure Possible cause Remedy
Oil leaking - from screw plug - from the oil drain valve
Gasket not tight Retighten screw.
Fittings loosened Retighten the fitting and screw.
Heavy V-belt wear Inadequately aligned belt pulleys Check V-belt pulley alignment and pretension of the belts.
Harmful ambient conditions (e.g. abrasive particles, chemical substances) Protect V-belt drive from environmental influences; sufficient ventilation must be ensured.
V-belt overloaded Replace V-belt if necessary; contact SEW-EURODRIVE.

Pressure switch not switching Air in the suction line of the oil pump Fill oil into the suction line and the oil pump and vent the pump at the pressure side.
Pressure switch connected incorrectly Check the connection.
Pressure switch defective Replace pressure switch.
Oil pump defective Contact SEW-EURODRIVE.
Malfunction in the oil-water or oil-air cooling system
Malfunction of the oil-water or oil-air cooling system Observe the separate operating instructions for the oil-water or oil-air cooling system.
Gear unit does not reach cold start temperature
Thermostat set incorrectly Check the setting of the thermostat.
Oil heating defective or connected incorrectly Check the oil heater for proper connection and function; replace if necessary.
