Adapter Construction
The adapter is made up of 3 sub-assemblies. They assemble via
connectors making the adapter modular. This way the sub-
assemblies can be replaced when they wear out.
When disassembling the adapter take care not to bend the pins.
When reassembling the adapter note the pin 1 indicators to align
the parts correctly.
