10.1.2 Replacement procedure of external sealing rings
The service life of the rotating seals depends on many factors:
Sliding speed;
Temperature;
Operating environment;
Level of dust;
Ageing of the compounds.
It is therefore impossible to establish a minimum duration of the component, which must be checked periodically to ensure
correct operation.
As well as in the case of leaks, we recommend replacing the rings during the periodic overhauls of the gear reducer, when
replacing the lubricant and in general at least every 4 years.
Locate the seal to be replaced and proceed as follows:
Drain oil (refer to section OIL CHANGE PROCEDURE );
Remove the sealing ring taking the utmost care not to cause any kind of damage to the seat and to the shaft
(scratches, dents, etc.);
Always use new seals of the same brand of those removed.
Proceed as follows when fitting the new ring:
Grease the rotating housing on the shaft with plenty of lubricant, as well as the sealing lip of the ring. The
recommended grease to be used is
AGIP-MU EP 2 (for sealing rings with double lip in FKM use the special grease
TECNOLUBE BC 101) ;
Fit the ring by taking care not to damage the sealing lip during insertion, especially with the sharp edges of the key
housings, with excessive shocks and deformations. In this case, it is recommended to use a lubricated plastic cover for
cover sharp parts to ensure easy assembly;
When positioning the ring axially, make sure the sealing lip does not coincide with the groove generated by the
previous ring.
10.1.3 Bearings
As in the case of the sealing rings, also the bearings are influenced by the operating conditions of the gear reducer, such
as the input speed, loads, operating temperatures, type of load applied and lubrication used, etc. Therefore, it is not
possible to provide an intervention interval and it is necessary to check the gear reducer on a monthly basis to detect
anomalous noise and/or vibrations. If even a slight deterioration in the noise or vibration levels is detected, stop the gear
reducer and contact Motovario.
