Engine

This engine section has been organized into sub-sec-

tions which show a progression for the complete

servicing of the Arctic Cat 4-stroke engines. For

consistency purposes, this section shows a complete

and thorough progression; however, for efficiency it

may be preferable to remove the engine as a com-

plete assembly, to remove and disassemble only

those components which need to be addressed, and

to service only those components. Also, some com-

ponents may vary from model to model. The techni-

cian should use discretion and sound judgment. For

engine-related servicing procedures, see Section 3

of this manual.
