When inspecting the flexible coupling, look for evidence or
conditions identified in the following steps:
A. Cracks in the surface of the rubber. May be caused by tor-
sional vibrations, excessive misalignment or exposure to
contaminants (heat, petroleum products, chemicals, ozone,
ultraviolet radiation, etc.), excessive system torques.
B. Deterioration of the rubber element, as evidenced by spongi-
ness or by black carbon-like dust on rubber surface. May be
caused by contaminants or excessive heat, either external or
internal to the coupling.
C. Cracked, bent or otherwise damaged flex plate or coupling
plate.
D. Bolt holes in flex plate or coupling plate are elongated oval
shaped, not round. This could be caused by improperly
assembled parts, loose parts, vibration or improperly torqued
parts.
E. Bolts/nuts -- bent, worn or stripped threads.
3. Inspect the hub, looking for the following:
A. Damaged or worn splines.
B. Cracked parts.
4. Replace any defective parts including defective fasteners.
Overhaul Interval
