Installing the Components of the Discontinued LDA Stack
If they are installed correctly, the inner components of the LDA form a perfect stack that
ensures smooth movement of the pistons.

To install the inner components of the LDA stack
1. Because the fit between the check valve holders an the lower displacement chamber is
loose, place the LDA on a flat surface, and then insert the lower displacement chamber
and check valve assembly. The orientation arrow on the lower displacement chamber
points away from the LDA body (see
Figure 76
).
2. Install the upper displacement chamber and two PEEK film seals.
3. Install the outlet module.
