Spare Parts and Replacement Procedures 8 - 11
All removal and replacement procedures are easier to perform on
bay-mounted rectifiers that have been removed from the bay.
Most component removals are straightforward and obvious.
Therefore, these procedures can be used as a guide by qualified
service personnel, rather than as step-by-step procedures. For
example, you may prefer to remove a part not called for in order
to make more room for access to a component being replaced.
Tables 8-D and 8-E provide the reassembly torquing
requirements for the electrical and mechanical connections in
the rectifier. Use these values unless otherwise directed in the
procedures.
