DISASSEMBLY AND REASSEMBLY
This subsection contains step-by-step disassembly procedures for the system. Reassembly is
the reverse of disassembly. Each procedure is supported by a simplified disassembly illus-
tration to facilitate removal. The Illustrated Parts Breakdown and parts lists for the system
unit are shown later in this subsection.
For complete disassembly of the system unit, follow the disassembly order listed in
Table 4-1. To reassemble, follow the table in reverse order.
