72-10-02 EXTENT OF DISASSEMBLY.
Line drawings reproduced in this section are similar to those
used in the parts catalog. The location of components and attaching parts in the illustration
will be sufficient to enable personnel to accomplish disassembly operations.
72-10-03 PARTS TO BE DISCARDED.
Discard all shakeproof washers, lockwires, tab washers, rubber
seal rings,
oil seals, gaskets, cotter pins, flex hoses, hose connectors and magneto coupling
(rubber) bushings in such a manner that they
will not be used again inadvertently.
Care
should be taken in removing gaskets from aluminum parts by scraping. Such removal should
be delayed
until the part is to be cleaned. (See TCM Service Bulletin
87-11R2, or current
revision applicable,) "100% Replacement Parts."
72-10-04 PRELIMINARY CLEANING.
Spray or brush with a solvent used for general cleaning of engine
parts.
Remove caked dirt on bolt heads and nuts especially. At the same time the oil sump
drain plugs should be removed to drain any remaining oil.
CAUTION.
.
.
Do not use a caustic or even mild alkaline cleaning solution for external
precleaning,
as
these solutions will also remove the "anodized" finish of aluminum parts.
