There are no scheduled maintenance intervals for the CD Couplings, and many of our CD Couplings run indefinitely in the application.  However, any jam-ups, overloads, or crashes on the equipment may require replacement of the disc packs.  It is also recommended to re-torque the disc pack bolts after several hours of operation following installation, where possible.
When installing or re-torquing the bolts, it is critical that the disc-pack bolts be torqued-to-spec per the Installation Instructions.  This is essential for proper operation and long life of the coupling.   The Instructions, including the recommended tightening torques, can be found under the “Downloads” section of our website.
Preventive maintenance considerations would involve periodically visually inspecting the coupling when the machine is shut down.  Things to look for include anything abnormal, such as obviously loose bolts, or any delamination of the disc pack.  Note that if there is any delamination showing, it does not mean the disc pack will imminently fail; however, it would be best practice to replace the disc-pack at the next opportunity.
