Review the following suggestions before working on the power plant.
1. To insure proper reinstallation and/or assembly, tag and mark all parts, 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: Dust caps used to protect open lines must always be installed OVER the tube ends and NOT IN
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 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 pins
must fit snugly in holes drilled in studs and bolts for locking purposes. Cotter pins should be installed so
the head fits into the castellation of the nut, and unless otherwise specified, bend one end of the pin
back over the stud or bolt and the other end down flat against the nut. Use only corrosion resistant steel
lockwire and/or cotter pins. Bushing plugs shall be lockwired to the assembly base or case. Do not
lockwire the plug to the bushing.
6. All gaskets, packings and rubber parts must be replaced with new items of the same type at reassembly.
Insure the new nonmetallic parts being installed show no sign of having deteriorated in storage.
7. When installing engine parts which require the use of a hammer to facilitate assembly or installation, use
only a plastic or rawhide hammer.
CAUTION: ENSURE THAT ANTI-SEIZE COMPOUNDS ARE APPLIED IN THIN EVEN COATS, AND
THAT EXCESS COMPOUND IS COMPLETELY REMOVED TO AVOID CONTAMINATION
OF ADJACENT PARTS.
8. Anti-seize lubrication should be applied to all loose-fit spline drives which are external to the engine and
have no other means of lubrication. For certain assembly procedures, molybdenum disulfide in either
paste or powdered form mixed with engine oil or grease may be used.
9. Temporary marking methods are those markings which will ensure identification during ordinary
handling, storage and final assembly of parts.
