2007–2011 Yamaha Grizzly 350 YFM35GW Owner's Manual (P/N LIT-11626-20-19)

• 632 PDF pages in two files - YFM35GW Owner's Manual P/N LIT-11626-20-19: 151 pages; 481-page service PDF containing the 366-page YFM400FAR Service Manual, literature no. LIT-11616-16-02, and the 115-page YFM350FAS Supplementary Service Manual, literature no. LIT-11616-17-32.
• Engine repair coverage reaches from removal and installation through the cylinder head, camshaft, rocker arms, valves, piston, crankcase, crankshaft, balancer gears, oil pump, oil cooler, transmission, recoil starter, and A.C. magneto.
• CVT and driveline procedures cover primary and secondary sheave service, clutch disassembly and inspection, middle-gear shim selection, front CV joints, differential gear-lash adjustment, and rear axle/final-drive setup.
• Brake, steering, and chassis work includes hydraulic brake bleeding, master-cylinder and caliper repair, rear drum-brake service, steering stem and knuckle work, ball-joint replacement, front-arm inspection, and swingarm service.
• Electrical diagnosis is supported by switch-continuity tests, circuit-specific troubleshooting for ignition, starting, charging, lighting, signals, cooling, and 2WD/4WD selection, plus full YFM400FAR and YFM350FAS wiring diagrams.
• Owner-level coverage includes controls, pre-operation checks, cold and warm starting, reverse operation, loading, terrain-specific riding techniques, scheduled maintenance, minor repair, and a starting-problem troubleshooting chart.

Match the Publication to the Model Label

The owner's manual is the first-edition April 2006 Yamaha publication for the YFM35GW. The workshop material has different identifiers: the supplement is labeled YFM350FAS, model code 5UH1, and Yamaha directs the reader to use it with the YFM400FAR base manual, model codes 5TE1 and 5TE5. The service publications are not labeled YFM35GW, so the ATV's model label should be checked before their specifications or repair procedures are applied.

Yamaha produced the service material primarily for dealers and qualified mechanics and assumes a basic understanding of mechanical repair. The separate owner's manual is the appropriate starting point for operators handling routine inspection, maintenance, and riding questions.

How the Base Manual and 350 Supplement Work Together

The YFM400FAR manual supplies the underlying workshop procedures, exploded assembly drawings, ordered job charts, torque data, lubrication references, wear limits, clearances, and electrical test specifications. The YFM350FAS supplement adds the 350-specific data and changed procedures for the air-cooled engine, oil-cooling system, balancer and oil pump, CVT sheaves and clutch, crankcase, transmission and middle gear, front differential, rear brake, steering, starter, signal system, and cooling controls. Neither service publication is complete by itself; Yamaha expressly pairs the supplement with the base manual.

The special-tool sections identify both US/Canadian tool numbers and their 90890-series equivalents. Examples include the crankcase separating tool YU-01135-A / 90890-01135, sheave spring compressor YM-04134 / 90890-04134, and gear-lash measurement tools YM-01467 / 90890-01467 and YM-01475 / 90890-01475. This matters for repair work such as crankcase separation, secondary-sheave service, and differential setup, where improvised tooling can damage parts or compromise the final adjustment.

Operational and Maintenance Coverage

The owner's manual lays out the requirements for operating and maintaining the YFM35GW. Its riding chapters address turning, uphill climbs, steep descents, crossing a slope, shallow water, rough terrain, and recovery from a slide or skid. It also covers protective apparel, the passenger prohibition, cargo limits, parking on slopes, and the risks of unauthorized modifications.

Separate emission-control and chassis maintenance charts organize the inspection schedule. Routine sections cover engine oil and filter-cartridge changes, final-gear oil, air-filter and spark-arrester cleaning, V-belt duct and case drains, spark-plug inspection, throttle and idle adjustments, brake wear and fluid checks, cable and pivot lubrication, battery and fuse service, bulbs, wheels, and basic troubleshooting.

Factory Data, Diagrams, and Repair Cautions

The set provides component-specific torque tables, fluid and lubricant data, inspection and wear limits, gear-lash and shim-selection data, and electrical resistance and output checks. Diagram coverage includes YFM400FAR coolant-flow and 2WD/4WD selecting-system circuits, YFM350FAS oil-flow and cable-routing views, ignition and electric-starting diagrams, and a full wiring diagram for each service publication.

Manual-specific cautions flag two easy ways to damage drivetrain parts. The middle-drive section identifies a left-hand-threaded bearing retainer and warns that pressing directly on the driven-shaft end will damage its threads. During differential gear-lash measurement, overtightening the temporary holding bolt can damage the ring gear. Brake, steering, engine, and driveline repairs can leave the ATV unsafe if assembly or adjustment is wrong, so work beyond the reader's training should be handled by a qualified technician.
