Inspect the removed diaphragm to assess the amount of wear and determine whether a
replacement is required. The example shown in Figure 82 is a diaphragm that is torn and
requires replacement. If a replacement is not required, clean any dirt or debris from the
existing diaphragm and spacers using a clean dry cloth and compressed air (if available). Do
not use solvents for cleaning as they may cause damage to some parts.

Inspect the pump housing for any dirt or debris. Some dirt is visible in the example shown in
Figure 83, this pump housing would require mild cleaning. Clean the pump housing using a
clean dry cloth and compressed air (if available). Do not use solvents for cleaning as they may
