7. MAINTENANCE AND REPAIR
For grease lubricated couplings, ensure that the recommended quantity of
grease is applied on the coupling teeth (internal & external) to such an
amount that the teeth are completely covered. After tightening the coupling
sleeves, fill the coupling with specified amount of grease from the grease nipple by
the use of grease gun.
The level of grease should be checked at regular intervals of 6 months to ensure
correct levels. The first grease change should take place before 3 months in
operation. To exchange the grease for the first time (after 3 months), dismantle the
coupling and thoroughly clean away inside to remove used grease, abrasive powder
etc. After cleaning, reassemble the coupling and fill the required quantity of grease
again for lubrication.
It is recommended that grease to be renewed at 2 years interval. Remove entire
used grease by dismantling the coupling and refill the coupling with new grease.
Maintenance checks:
a. Check for vibration and noise
b. Check for leakage
c. Check for damages on gear teeth
d. Check for damages and deterioration of `O'-ring
e. Check for deterioration of grease.
Checks mentioned above in Sr. No. a & b can be made by observing from outside
after comparing with condition under normal operation. The other checks should be
carried out every six months by dismantling the coupling.
Damaged ‘O’ rings must be replaced.
In case of high ambient temperature, frequent overloaded condition,
frequent reverse operation, large parallel misalignment and angular
misalignment, ensure that the checking intervals are shortened.
Note:
Correct initial installation, accurate alignment, usage of right quantity and quality of
lubricant will ensure longer life and smooth/trouble free operation of the coupling.
8 STORAGE
All couplings are to be stored and handled in conditions free from compression, tension or other
deformation.
Attention is drawn to the need to keep the product away from heat or continual sunlight.
The coupling components are supplied in storable conditions and can be stored in a dry, covered
place for an indefinite time.
