2. Place the repeller (262) in the backplate (444) with the sleeve side up.
3. Place a Teflon gasket (264) on the backplate (444) and align the holes in the gasket with the holes in
the backplate.
4. Place a stuffing-box cover (184) on the backplate (444) and align the holes in the gasket with the holes
in the backplate.
5. Install four socket-head capscrews (265) and tighten them securely.
