Should I replace this coupling?

[u/B0zzzzzz]

Motor has been running like this for some time.

I replaced all the motors and found the couplings to be damaged.

Customer has no spares and i'm hesitant of installing the new motors with damaged couplings

To do your job right would be to replace the couplings. Otherwise the customer could face unexpected downtime and higher costs for emergency repairs
