Information/Foreword
This Arctic Cat Service Manual contains service, mainte-
nance, and troubleshooting information for the 2016 Arctic
Cat Wildcat Sport. The complete manual is designed to aid
service personnel in service-oriented applications.
This manual is divided into sections. Each section covers a
specific vehicle component or system and, in addition to
the standard service procedures, includes disassembling,
inspecting, and assembling instructions. When using this
manual as a guide, the technician should use discretion as
to how much disassembly is needed to correct any given
condition.
This service manual is designed primarily for use by an
Arctic Cat CatMaster Basic Level technician. The proce-
dures found in this manual are of varying difficulty, and
certain service procedures in this manual require one or
more special tools to be completed. The technician
should use sound judgement when determining which
procedures can be completed based on their skill level
and access to appropriate special tools.
NOTE: Whenever a part is worn excessively, cracked,
or damaged in any way, replacement is necessary.
When replacement of parts is necessary, use only genuine
Arctic Cat parts. They are precision-made to ensure high
quality and correct fit. Refer to the appropriate Illustrated
Parts Manual for the correct part number, quantity, and
description.
All Arctic Cat publications and decals display the words
Warning, Caution, Note, and At This Point to emphasize
important information. The symbol

vehicle-related damage. Follow the directive because it
deals with the possibility of damaging part or parts of the
vehicle. The symbol

tain and specific procedures to promote efficiency and to
improve clarity.
