Example: T5 = 5 x 0.050 = 0.250”

All couplings should be inspected at routine shutdowns or every six to twelve months (Or 4,500 to 9,000 operating hours), depending on the duty of the application. Remove the ring and unwrap the insert. Inspect the insert for signs of wear. Minor cracking or tearing of the belt portion of the insert will not affect coupling performance. If any cracks or tears are present in the lobes of the insert, the insert should be replaced. Normal wear appears as slight indentations in the insert lobes where the hub wings make contact. If the indents exceed approximately 0.050 X’s the size coupling, the insert should be replaced.

Up to ¼” deep indents would be permitted before insert replacement is needed on a T-5 coupling.

The alignment and gap (E dimension) of the two coupling halves should be rechecked, and adjusted if needed. The insert and ring can then be installed.
