The following data covers the basic steps for
rebuilding the ICC 125cc shifter engine. It
is intended to offer a look inside the engine
for would be DIY’s. It is not intended
to be the final word on engine rebuilding but
rather a generalization of steps and procedures
required to rebuild an ICC shifter kart engine.
All engine technicians have their own sequence
of operations, methods and personal touches
for their customers. If you decide to try a
rebuild on your own you will discover that
there are other procedures that will work as
well for you.
The engine in the images is an older TM
K8 that happened to be available when the
data was gathered for publication. But it
is representative of most ICC engines in
use today. If the rookie technician gets
familiar with one make the others are very
much the same.
For first timers recording steps by writing
notes to refer to may be helpful. IMO the
ICC engine is a fun engine to rebuild and
does not pose any real challenges beyond
the scope of a standard rebuild. The rebuild
of the crankshaft has been left out to keep
instructions simple and within the reach
of the apprentice re-builder. It will be
covered in a later issue of NKN. If you decide
to give it go, have fun and use your email
if you need help.
