Clean surfaces prevent the casing gasket from partially adhering to the casing due to
binders and adhesives in the gasket material.

8. Transport the back pull-out assembly to a clean work area for further disassembly.

during reassembly.
Coupling hubs are normally mounted flush with the end of the shaft.
2. Remove the coupling hub using a spanning-type puller or puller holes provided in the hub.
Refer to the coupling manufacturer's instructions for assistance.
