Chapter 7 Section I: Replacement Procedures
Section I: Replacement Procedures
This section contains removal/installation procedures for components that are
replaceable at the field service maintenance level. These procedures are
listed below.
IMPORTANT
Do not attempt field repairs of electronic components or assemblies.
Replace a malfunctioning electronic assembly with an operational
spare. Most electronic problems are corrected by replacing the circuit
board, sensor, or cable that causes the fault indication. The same is true
of failures traced to the hammer bank coils and electronics: you must
replace the entire shuttle frame assembly. It is not field repairable.
(Hammer spring assemblies are the only replaceable components of the
shuttle frame assembly.)
