1995–2002 Yamaha Wolverine 350 YFM350FX Supplementary Service Manual (P/N LIT-11616-09-58)

• Combines 440 PDF pages of Yamaha factory service information: base manual LIT-11616-09-58 / 4KB-28197-20 plus supplements LIT-11616-09-95 / 4KB-28197-21, LIT-11616-12-03 / 4KB-28197-22, LIT-11616-13-05 / 4KB-28197-23, LIT-11616-14-02 / 4KB-28197-24, and LIT-11616-15-07 / 4KB-28197-25.
• Identifies the covered Wolverine 350 builds across the 1995-2002 range by model code, including YFM35FXG, YFM35FXH, YFM350FXLC, YFM350FXM/YFM350FXMC, YFM350FXN, and YFM350FXP, with USA, California, Canadian, and European codes where the publications specify them.
• Takes engine repair well beyond routine service, covering engine removal and remounting, cylinder-head and valve work, piston and cylinder inspection, crankshaft and balancer service, oil-pump repair, primary and secondary clutch work, shifter and transmission service, cam timing, and final adjustment.
• Handles the full shaft-drive and chassis side of the machine, including middle gear and universal-joint service, differential and CV-joint repair, rear final-drive setup, hydraulic brake overhaul and bleeding, steering and toe-in work, front suspension, and swingarm service.
• Supports electrical fault isolation with CDI ignition, electric-starting, charging, lighting, and signal-system circuit diagrams; switch, relay, starter-motor, pickup-coil, source-coil, and stator tests; cable-routing drawings; and model-specific wiring diagrams.
• Supplies the factory reference data behind the procedures, including maintenance schedules, lubrication charts, torque tables, fluid specifications and capacities, wear limits, clearances, electrical test values, special-tool references, exploded assemblies, and troubleshooting charts.

The base service manual provides the repair foundation for the air-cooled, four-stroke, single-cylinder Wolverine 350, while the supplements layer in later production changes instead of repeating the entire book. Yamaha prepared this material primarily for dealers and qualified mechanics, and it assumes the user already understands the mechanical principles and workshop practices involved in ATV repair. Because many engine, axle, brake, and suspension procedures require the machine to be raised or major assemblies to be removed, the ATV needs to be securely supported before work begins.

440 PDF pages total: YFM350FXN supplement, 16 pages; YFM350FXP supplement, 25 pages; scan divider, 1 page; YFM35FXH supplement, 20 pages; YFM35FXG base service manual, 339 pages; YFM350FXM/YFM350FXMC supplement, 23 pages; and YFM350FXLC supplement, 16 pages.

Production Changes Covered

The FXH material documents the BST34 carburetor configuration, revised cable routing, ignition data, and the parking-brake engine-revolution limiter. The California FXLC section adds its own carburetor, engine, chassis, maintenance, spark-arrester, and wiring information. For the FXM/FXMC, Yamaha added recoil-starter and left-crankcase-cover procedures, revised differential/CV-joint data, and a matching wiring diagram.

The FXN supplement updates engine and electrical specifications, periodic maintenance data, valve/camshaft/rocker-arm assembly information, and steering-system installation. The FXP supplement adds revised brake and cable-routing details, DC-CDI ignition and signal-system troubleshooting, switch checks, and a dedicated YFM350FXP wiring diagram. These supplements are intended to be used with the earlier publications included in this same PDF.

Workshop Depth, Diagrams, and Special Tools

The drivetrain chapters cover middle-gear and final-drive disassembly, bearing and seal work, shim selection, gear-lash measurement and adjustment, CV-joint service, and operational checks after assembly. Tool callouts include the YM-01231 / 90890-01231 gear-lash measurement tool, YM-04062 / 90890-04062 universal-joint holder, YM-01462 / 90890-01462 44 mm hex wrench, and YU-33270 / 90890-01362 flywheel puller.

Useful drawing sets include the middle-gear and universal-joint exploded view, differential and constant-velocity-joint assembly, rear axle/final-drive layout, CDI ignition circuit, electric-starting circuit, and the model-specific YFM350FXP and YFM350FX wiring diagrams. The manual also flags repair mistakes that can ruin parts: insufficient shaft-drive gear lash is described as extremely destructive to the gear teeth, while striking the rear axle directly with a hammer can damage its threads and splines.
