Typical Configuration
(Components may vary depending on application)
1. Place the gears and the suction shoe on the pump body. Affix the spring to the pump body to hold the
suction shoe in place. Using screw (11) and suction shoe spring (10), put screw through the end loop in the
spring so that the head of the screw is on the same side as the 90 degree bend. Now start the screw into
the pump body, but do not tighten.
2. Next, place the top leg of the spring over the top of the suction shoe and the bottom or horizontal leg
against the side of the suction shoe. Lightly tighten.
3. Check that the horizontal leg of the suction shoe spring is resting against the side of the suction shoe.
Tighten spring screw with spring just touching the suction shoe.
4.
Check that the horizontal leg of the spring does not extend past the pilot diameter of the pump body when
looking directly down on the suction shoe. (See Figure 1, above). If the spring does extend past the pilot,
loosen spring screw and push the spring back towards the screw, and repeat steps 1 and 2.
