2018 Yamaha WOLVERINE X4 Service and Repair Manual

Part number LIT-11616-31-40 is what a Yamaha dealer reached for in 2018 when a Wolverine X4 came into the shop. The base X4 carries model code YXF85WPXJD, and the same volume also documents the X4 HUNTER and the X4 SE, since Yamaha built those on shared service procedures.

That shared coverage matters when you are reading a page. Specifications and routing notes are tied to codes, so confirming YXF85WPXJD against your own identification plate keeps you from following a figure written for a sibling model.

Inside is the factory presentation of the work: periodic maintenance intervals, engine and drivetrain disassembly, chassis and suspension service, fuel and electrical diagnosis, torque values and the wiring diagrams. Illustrations are the factory drawings, sectioned so you can see how a component sits before the fasteners come out.
