Malfunctions / Breakdowns Type 494._ _ _._ (continued)

 

Result of 

Malfunction 

Possible Causes 

Solutions 

Premature wear  

on the elastomeric 

element 

Incorrect alignment 

1) 

Set the system out of operation 

2) 

Find / resolve the cause of incorrect alignment 
(e. g. loose foundation screws, motor securement breakage, heat 
expansion of system components, changes in the coupling 
installation dimension “E”) 

3) 

Check the clutch for wear 

4) 

Insert a new elastomeric element 

e.g. contact with  

aggressive liquids / oils, ozone 

influences, excessively high ambient 

temperature etc., which lead to 

physical changes in the elastomeric 

element 

1) 

Set the system out of operation 

2) 

Dismantle the clutch and remove the remainders of the 
elastomeric element 

3) 

Check the clutch parts and replace if damaged 

4) 

Insert a new elastomeric element, install clutch components 

5) 

Check the alignment and correct if necessary 

6) 

Make sure that further physical changes to the elastomeric 
element can be ruled out 

The ambient or contact temperatures 

permitted for the elastomeric element 

are exceeded 

1) 

Set the system out of operation 

2) 

Dismantle the clutch and remove the remainders of the 
elastomeric element 

3) 

Check the clutch parts and replace if damaged 

4) 

Insert a new elastomeric element, install clutch components 

5) 

Check the alignment and correct if necessary 

6) 

Check the ambient or contact temperature and regulate them  
(if necessary, use other elastomeric element materials) 

Premature wear  

on the elastomeric 

element (material 

liquidation inside the 

elastomeric element 

toothing) 

Drive vibrations 

1) 

Set the system out of operation 

2) 

Dismantle the clutch and remove the remainders of the 
elastomeric element 

3) 

Check the clutch parts and replace if damaged 

4) 

Insert a new elastomeric element, install clutch components 

5) 

Check the alignment and correct if necessary. 

6) 

Find the cause of vibration (if necessary, use an elastomeric 
element with a lower or higher shore hardness)
