Installing the plunger seal wash system 3-21
Installing head support components (1515/1525 pump only)
Replace the high pressure seal while the head is removed. See page 5-6 for
more information.
Perform these steps only if you have the 1515 or 1525 pump:
1. Lay the head support on a hard surface, back side up.
Tip:
You can identify the back side of the pump head support by its
larger wash seal cavity. The following figure shows the back side of the
pump head support.

2. Insert the wash seal spacer into the wash seal cavity in the center of the
head support.
Tip:
Because the spacer fits tightly, start its edge into the cavity at a
slight angle and then rotate it into the cavity while pressing down.
