14. This is what the seal will look like when in new condi-
tion. The sealing face will not have gouges, cracks,
chips or burnt edges. Replace if any of the previous
conditions apply.
13. Hit the backside of the socket until the seal drops to
the workbench below.
15. To remove the rotating seal from the impeller it might
become necessary to apply some liquid soapy water
to loosen it from the impeller. After the soapy water
loosens the seal in the impeller, take a small screw
driver and pry gently upward making sure not to
gouge the surface.
16. The impeller must be inspected for no cracks, chips,
and blades that are missing or broken off. Replace
with new if these conditions apply.

17. Check the condition of the volute seal for cracks, worn
spots, and overall condition. Replace with new if
necessary.
18. Check the condition of the volute. If cracked chipped or
bent, it must be replaced.
19. When reinstalling the back plate to the engine make
sure the weep hole faces downward. Weep hole must
be free from debris.
20. When replacing with a new seal, silicone compound
is not needed. However, if original seal is removed and
replaced back into pump back plate, then a small
amount of silicone sealant will help seal it. Place a thin
bead of sealant around the metal part of the seal.
