5 - 9 DISASSEMBLY OF
TRANSMISSION TO
REMOVE MAJOR
PARTS AND UNITS
1. Preliminary Instructions
a. Before starting disassembly
of the transmission it should be
thoroughly cleaned externally to
avoid getting dirt inside.
b. Place t r a n s m i s s i o n on a
CLEAN work b e n c h and use
CLEAN tools during disassembly.
Provide CLEAN storage space for
parts and units removed from
transmission. An excellent work-
ing arrangement is provided by
assembling the transmission to
Holding Fixture J-8763. See Fig-
ure 5-100.
c. The transmission c o n t a i n s
parts which are ground and highly
polished, therefore, parts should
be kept separated to avoid nicking
and burring surfaces.
d. When disassembling transmis-
sion carefully inspect all gaskets
at times of removal. The imprint
of parts on both sides of an old
gasket will show whether a good
seal was obtained. A poor imprint
indicates a possible source of oil
leakage due to gasket condition,
looseness of bolts, or uneven sur-
faces of parts.
e. None of the parts require
forcing when disassembling or
assembling transmission. Use
a rawhide or plastic mallet to
separate tight fitting cases - do
not use a hard hammer.
