Engine

This engine servicing section has been organized into

sub-sections which show a progression for the com-

plete servicing of the Arctic Cat engine. For consis-

tency 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.

NOTE: Some illustrations and photographs used

in this section are used for clarity purposes only
and are not designed to depict actual conditions.
