e latest when they reach the end of their service life. Further information You can find additional information on measuring the vibration levels at rolling-contact bear- ings in the operating instructions of the measurement sensor provided in the complete gear unit documentation. Servicing 8.3 Maintenance and servicing work 7 Edition 0/2 A5-0 en8.3.3 Cleaning the gear unit 8.3 Maintenance and servicing work Introduction Layers of dust may affect the dissipation of heat through the surface of the gear unit, result- ing in overheating. Depending on the operating conditions, it may therefore be necessary to clean the gear unit more frequently than stated in the maintenance schedule. Procedure To clean the gear unit, proceed as follows: 1.Use hard brush to remove any stubborn dirt from the gear unit. Never use high-pres- sure cleaning device. 2.Remove any spots of corrosion. 8.3.4 Inspecting the rotary shaft sealing ring 8.3 Maintenance and servicing work Service life of rotary shaft sealing rings Rotary shaft sealing rings are wearing parts that need to be replaced after the wear limit is reached. The service life of rotary shaft sealing rings is influenced by many different para- meters: Circumferential speed at the sealing lip Temperature Internal pressure in the gear unit Lubricant viscosity Chemical composition of and additives in lubricants Mounting position (supply of lubricant to sealing lip) Dirt particles or metal abrasion dust in the lubricant Shaft sealing ring material As result of these many influencing parameters, it is not possible to make definitive state- ment about the likely service life of rotary shaft sealing rings. It is therefore important to in- spect them regularly. Only in this way is it possible to detect the signs of lubricant loss in the gear unit. 8.3.5 General inspection of the gear unit 8.3 Maintenance and servicing work Arrange for Flender Customer Services to perform general inspection on the gear unit.
