RECOMMENDED MAINTENANCE

ALL COUPLINGS SHOULD BE INSPECTED AT ROUTINE SHUT DOWNS OR EVERY SIX TO TWELVE MONTHS (OR 4500 TO 9000 HOURS) DEPENDING ON THE DUTY OF THE APPLICATION. REMOVE THE RING AND UNWRAP THE INSERT. INSPECT THE INSERT FOR WEAR. MINOR CRACKING OR TEARING OF THE BELT PORTION OF THE INSERT WILL NOT AFFECT THE FUNCTION OF THE COUPLING. IF THERE ARE ANY CRACKS OR TEARS IN THE LOBES OF THE INSERT IT SHOULD BE REPLACED. NORMAL WEAR WOULD BE SLIGHT INDENTS IN THE LOBES OF THE INSERTS WHERE THE WINGS OF THE HUBS MAKE CONTACT. IF THE INDENTS EXCEED APPROXIMATLY .050 X’S THE SIZE COUPLING, THE INSERT SHOULD BE REPLACED. EXAMPLE M5 = 5 X .05 = .250 UP TO ¼” DEEP INDENTS WOULD BE PERMITTED BEFORE INSERT REPLACEMENT IS NEEDED ON AN M-5 COUPLING THE ALIGNMENT AND GAP (E DIMENSION) OF THE TWO COUPLING HALVES SHOULD BE RECHECKED, AND ADJUSTED IF NEEDED. THE INSERT & RING CAN THEN BE INSTALLED.
