What our service work and the manufacturer documentation say about keeping this model running.
Inspect resilient elements, flanges, bolts, alignment marks and signs of fretting, heat or contamination. Compare coupling condition with shaft vibration and torsional behaviour after propulsion changes. Verify fastener condition and alignment after replacement. Refer to the manufacturer documentation for the exact figure for allowable deflection, alignment and replacement criteria.
Carry complete resilient-element sets, approved fasteners, locking devices and alignment or installation consumables for the installed coupling.
