3.1 COMPONENT REUSE
When carrying out procedures within this manual the guidance is to re use com -
ponents. It should be noted that components like washers, circlips, o-rings and
fasteners are easily damaged and should be replaced if signs of wear or tear are
present.
3.2 CLEANING PROCEDURES
When a fastener (new or old) is to be used within a procedure outlined within this
manual, it first requires cleaning. To clean a fastener follow the below process;
Prepare the threads using an appropriate aqueous or solvent based cleaner.
Wipe the threads ensuring no corrosion inhibitor, dirt or debris remains.
If there is any stubborn debris use a fine wire brush to agitate, remove and then
prepare the threads with an appropriate cleaner.
Assess the thread for signs of wear and tear and replace with new if required.
3.3 APPLICATION OF THREADLOCKER
This procedure should be followed for every use of threadlocker within this man -
ual. Ideally refer to the manufacturers specifications for the application of
threadlocker. If these are unavailable follow the below process;
1. Prepare the threads using an appropriate aqueous or solvent based cleaner.
Wipe the threads ensuring no corrosion inhibitor, dirt or debris remains.
2. Allow the threads to dry after cleaning ensuring no trace of the cleaners used
in the first stage remains.
3. Apply a few drops of threadlocker to the section of the bolt where the nut will
sit.
4. Slowly fit the nut onto the bolt allowing the threadlocker to spread evenly.
5. Allow the threadlocker to cure for 24 hours. During this time movement of the
assembly should be kept to a minimum. In cases where this is not possible, an
accelerator may be used. Refer to the manufacturers specifications for pro -
cess.
3.4 STANDARD TORQUE SETTINGS
This chart specifies tightening torques for standard metric ISO fasteners with a
standard ISO thread pitch. Tightening torque specifications for special compo -
nents or assemblies are provided for each chapter of this manual. To avoid warp -
age, tighten multi-fastener assemblies in a crisscross pattern and progressive
stages until the specified tightening torque is reached. Unless otherwise speci -
