The following suggestions should be applied wherever they are needed when working on the power plant.
1. To insure proper reinstallation and or assembly. tag and mark all pans, clips, and brackets as to their
location prior to their removal and or disassembly.
2. During removal of various tubes or engine parts. inspect them for indications of scoring, burning or
other undesirable conditions. To facilitate reinstallation, observe the location of each part during removal.
Tag any unserviceable part and 'or units for investigation and possible repair.
3. Extreme care must be taken to prevent foreign matter from entering the engine, such as lockwire.
washers, nuts. dirt, dust, etc, This precaution applies whenever work is done on the engine, either on or off the
aircraft. Suitable protective caps. plugs, and covers must be used to protect all openings as they are exposed.
-NOTE

the tube ends and NO TIN the tube ends. Flow through the lines may
be blocked off if lines are inadvertently installed with dust caps in the
tube ends.
4. Should any items be dropped into the engine, the assembly process must stop and the item must be
removed, even though this may require considerable time and labor. Insure that all parts are thoroughly clean
before assembling.
5. Never reuse any lockwire. lockwashers. tablocks. tabwashers or cotter pins. All lockwire and cotter

paste or powdered form mixed with engine oil or grease may be used.
-CA UTION-
Ensure that Anti-seize compounds are applied in thin even coats,
and that excess compound is completely removed to avoid
contamination of adjacent parts.
