and direction. This will help you to reassemble them. Especially note the order of the piston
cup, piston cup spacer, and compression ring, and the directions they face. These
directions are critical to proper functioning of this equipment.
2. Use a wrench to remove the two hex cap screws which secure the cylinder (15991-1)
and foot valve body to the center section of the pump (85728-3).
NOTE: Loosen the hex screws alternately to prevent distorting them.
3. Remove the foot valve body and the cylinder (15991-1) from the pump.
Disassemble Foot Valve Assembly:
1. Separate the cylinder from the foot valve assembly by pulling them apart. Inspect the
cylinder for damage or wear.

NOTE: The two O-Rings on the cylinder will need to be replaced during reassembly.

4. Remove the spring and the ball.
NOTE: The ball may need to be replaced during reassembly.
5. Check the interior of the foot valve body for material buildup or damage.
