Reassembling the LDA
Reassemble the LDA after replacing the piston seals or completing a corrective or
troubleshooting procedure that requires you to disassemble it.

To reassemble the LDA
1. Place the LDA on a clean, level surface.
2. Verify that the first check valve is in the appropriate orientation (see Figure 81 ), and then
insert it into the main body of the LDA (see Figure 82 ).

CAUTION The proportioning valve cables are hardwired to the proportioning valves.
Attempting to remove the cables from the valves can break the electrical wires inside
the insulated cables.
For rendering purposes only, Figure 82 on this page through Figure 86 on page 91
show the LDA without the cables.
