Engine; Removing Engine (120 Cc Model) - Arctic Cat 660 cc Service Manual

This engine section has been organized into sub-sec-
tions which show a progression for the complete ser-
vicing of the Arctic Cat 4-stroke engine. For
consistency purposes, this section shows a complete
and thorough progression; however, for efficiency it
may be preferable to remove the engine as a complete
assembly, to remove and disassemble only those com-
ponents which need to be addressed, and to service
only those components. Also, some components may
vary from model to model. The technician should use
discretion and sound judgment. For engine-related ser-
vicing procedures, see section 3 of this manual.
NOTE: Some illustrations and photographs used
in this section are used for clarity purposes only
and are not designed to depict actual conditions.
