(Figure 16) .
Older models have acorn nuts and plastic washers on
the front of the pump. If equipped, remove these first
(Figure 17).
3. Install new wear ring, making sure pump surface and
ring are clean and the ring sits flat against the pump.
4. Reinstall stainless steel screws.
5. Reinstall plastic washers, and acorn nuts on older
models.

assembly (Figure 18).

400 grit or higher sandpaper. If sleeve surface is worn,
grooved or pitted, replace drive sleeve.
Worn or damaged impeller/drive sleeve may cause the
pump to under perform or become unbalanced, causing
mechanical seal damage.

damage the carbon face during installation.
3. Install new seal half onto drive sleeve.
