HOW TO USE THIS MANUAL
HOW TO USE WORK PACKAGES (Continued)
Referring to another Work Package
Steps within a work package may refer to another work package in this manual:
“Remove fuel injection pump assembly (WP 0115).”
In this example, only the REMOVAL part of the referenced work package is to be performed.
Cleaning and Inspection
General cleaning and inspection procedures for every work package are found in WP 0028,
General Maintenance Instructions.
Use these procedures to clean and inspect any part being
removed, repaired, or installed.
Special cleaning and inspection, if required, will be covered in
the procedural work package.
Check
This term is used when an instruction step requires the use of a tool to determine a specific
value.
When checking the fit of a part, a range of acceptable values may be provided.
The
letter L or T may follow a value.
L means looseness of fit, T means tightness of fit.
Go to End of Work Package
This term is used in a work package step that contains a conditional situation that might
require performance of more steps.
If no more steps are to be performed, the work package or
work package element is complete, and you are directed to GO TO END OF WORK
PACKAGE.
Anytime you arrive at END OF WORK PACKAGE, you must return to the
maintenance work package or troubleshooting work package that sent you to that work
package.
