PREPARATION AND SUGGESTIONS
Provide a well lighted working area with enough
space for parts and tools to be spread out.
A
work
stand is essential for holding the engine securely.
When disassembling the engine, lay parts out in the
order they were removed. Have several boxes avail-
able
so
that parts belonging to certain groups can be
kept together. Tag parts if there is a possibility of
confusion.
Use the PARTS MANUAL for reference during
reassembly. The exploded view illustrations will help
identify parts, show the components of individuaf
assembly groups and
show
the order of
reassembly.
Often it
is
not necessary to disassemble the entire
engine. The instructions contained in this manual are
arranged by components. If entire engine dis-
assembly is required, locate the reassembly instruc-
tions under headings of the various parts.
NOTE:
Drain oil from crankcase before disas-
se
m bly.
While the engine is partly or fully dismantled, clean
and inspect all parts and replace as needed. During
reassembly use new gaskets and lubricate all bear-
ing surfaces.
Torque parts
to
specifications where given
(see
‘SPECIFICATIONS’). Use caution in tightening all
other screws and nuts to avoid stripping threads or
breaking flanges.
