4. To install the new backup piston seal:
a. Hold the new backup piston seal
(P/N 063382) with the grooved side
facing down, and insert the shaft of the
piston through the seal.
b. Insert the piston into the center hole in
the spacer.
c. Push the piston into the spacer until
the top of the piston is flush with the
spacer. A clicking sound indicates that
the seal is correctly seated.
The backup piston seal is made of soft plastic. Do not press on the
seal with anything hard or sharp, including your fingernail. If the seal
is nicked or gouged, it will not seal properly and may result in leaks.
d. Pull out the piston. The top of the seal should
be flush with the surface of the spacer.
e. Press the seal holder onto the spacer.
To remove the old piston seal from the pump head:
1. Fill the pump head cavity with deionized water by injecting the liquid through
the piston opening.
2. Reinsert the piston about 3 mm (0.125 in) into the seal.
