IMPORTANT: The circular groove formed by the impeller sealing bead should be dis-
regarded when inspecting cover (Step 5) and plate (Step 9), as the depth of the groove
will not affect water pump output.

groove(s) (other than impeller sealing bead groove) in cover roof are more than 0.030
in. (0.762 mm) deep.
