Yamaha Wolverine 350 ATV Manual Set – 2009 (P/N LIT-11616-09-58)

The first-edition service publications use the base manual for core repair procedures and the supplements for model-specific updates. The owner’s manual covers controls, riding and routine maintenance.

Model coverage: The YFM350FXT is covered by the owner’s manual only. Workshop coverage follows the models listed in the service publications above.

PDF Search, Bookmarks and Wiring Detail

Search and navigation: The owner’s manual has searchable text and chapter bookmarks, with a few image-based pages. The workshop PDF has bookmarks for the base manual and all five supplements. Text search works in the N and P supplements. Small labels on the LC and P wiring diagrams are readable when zoomed in, while some labels in the base manual’s circuit diagrams remain hard to distinguish.

The ZIP contains 609 pages across two printable PDFs. The 440-page workshop PDF includes one separator sheet. The 169-page owner’s PDF includes three back-matter pages, two of which make up a safety reply card.

ATV Operation, Overhaul and Electrical Diagnosis

This selection of covered topics highlights the main jobs and references. The set also includes engine lubrication diagrams and guidance on long-term storage.

• Controls and riding: Pre-ride checks, cold and warm starting, shifting and reverse, loading and break-in, plus illustrated guidance for hills, side slopes, shallow water, rough terrain and skid recovery.
• Engine and transmission: Engine removal, crankcase separation, cylinder-head and valve-train repair, piston and crankshaft inspection, cam-chain timing, clutch and transmission work, and oil-pump service.
• Shaft drive: Middle-gear setup, differential and CV-joint repair, rear axle and final-drive disassembly, shim selection, gear-lash measurement and post-repair checks.
• Brakes and chassis: Pad, caliper and master-cylinder service, hydraulic bleeding, wheel service, steering and tie-rod inspection, and front and rear suspension and swingarm work.
• Fuel and electrical systems: Carburetor overhaul and fuel-level adjustment, starter motor service, switch and connector checks, and fault isolation for ignition, starting, charging, lighting and signals.
• Workshop references: Cable-routing drawings, exploded views of the differential and rear final drive, torque and wear specifications, and electrical troubleshooting flowcharts.

The owner’s manual is written for ATV riders and covers routine checks and maintenance. Yamaha prepared the service literature primarily for dealers and qualified mechanics. Internal overhaul and gear setup call for mechanical experience and the specified measuring tools.

Owner Maintenance and Controls

The owner’s manual identifies the ATV’s warning labels and explains the speed limiter, parking brake, recoil starter, fuel cock, choke and shock adjustments. Its specifications identify a constant-mesh five-speed transmission with reverse, a wet centrifugal automatic clutch and shaft drive.

The maintenance sections cover engine oil and filter service, final and differential gear oil, axle boots, spark plug, air filter, spark arrester, valve clearance, idle, brakes, battery, fuses and lighting. A troubleshooting chart separates basic fuel, compression and ignition checks.

Workshop Updates and Diagnostic References

Model-specific changes: H covers regional identification, cable routing, carburetor specifications and the parking-brake rev limiter. LC adds California-specific maintenance and spark-arrester guidance. M/MC revises recoil-starter and left-crankcase-cover service and updates differential, CV-joint, rear axle and final-drive work. N adds valve-train specifications and tie-rod setup. P updates cable routing and brake-light switch, ignition and signal diagnostics.

Electrical diagnosis: The H supplement explains how the parking-brake switch activates the rev limiter, helping distinguish expected limiter operation from an ignition fault. LC and P include full-vehicle wiring diagrams. The base manual includes individual circuit diagrams for ignition, starting, charging, lighting and signals.

Tools and precautions: The base manual identifies the crankcase separator (YU-01135-A / 90890-01135), the rear final-drive lash tool (YM-01231 / 90890-01231) and its dial gauge (YM-03097 / 90890-03097). It also lists a dynamic spark tester or ignition checker. Yamaha warns that spinning dry bearings with compressed air can damage them and that insufficient shaft-drive lash can damage gear teeth. Follow the factory precautions for fuel, rotating parts, battery current, brake hydraulics and work with the ATV raised.

Gear Lash and Ignition Coil Specifications at a Glance

For the YFM35FXG, the base manual specifies middle-gear lash of 0.1–0.3 mm and rear final-drive lash of 0.1–0.2 mm. Each specification is checked at four positions.

For YFM350FXP ignition diagnosis, the supplement lists coil resistance of 0.18–0.28 Ω on the primary winding and 6.32–9.48 kΩ on the secondary winding at 20 °C (68 °F).
