Document Structure and Coverage

The 409-page base publication is Yamaha’s YXR45FAV Service Manual, first edition August 2005. It is organized by specifications, periodic checks and adjustments, engine, cooling, fuel, drive train, chassis, electrical systems, and troubleshooting. Its tables explicitly separate the U.S., Canadian, and European 2P5 builds, including market-specific vehicle data and different indicator/meter arrangements for the U.S. version versus the Canadian and European versions.

The 12-page 2008 YXR45FX Supplementary Service Manual, first edition August 2007, is a focused update rather than a replacement service manual. It adds model-code and chassis data, revised seats/console/instrument-panel removal, the passenger handhold and strap arrangement, side-door service, and related chassis torque information. Yamaha directs the technician to use it with the YXR45FAV base manual and the YXR45FW Supplementary Service Manual LIT-11616-20-50 / 2P5-F8197-11. That YXR45FW publication is not included in this PDF set. The full wiring schematic supplied here is labeled YXR45FAV 2006, and the YXR45FX supplement adds no replacement engine or electrical chapters. Treat this as the documented 2006 base manual plus the specified 2008 chassis update, not blanket 2006–2009 coverage.

Workshop Repair Depth

Engine coverage extends through cylinder-head removal and installation, valve and valve-seat work, piston and cylinder inspection, timing-chain service, A.C. magneto and starter-clutch checks, primary and secondary sheave repair, clutch inspection, crankcase assembly, crankshaft and balancer installation, oil-pump checks, transmission inspection, and middle-drive gear shim selection and backlash measurement.

Drive-train procedures include front and rear CV-joint repair, universal-joint assembly, differential and final-drive teardown, pinion and ring-gear positioning, gear-lash adjustment, and differential gear-motor checks. Chassis sections address brake pads, master cylinder, front and rear calipers, hydraulic bleeding, steering column and steering assembly, tie rods, steering knuckles, ball-joint replacement, suspension arms, stabilizer, shock absorbers, wheels, hubs, brake discs, enclosure panels, cargo bed, and seat belts.

Electrical testing is organized by circuit. Separate sections cover switch continuity, bulbs and sockets, ignition, electric starting, charging, lighting, signaling, radiator-fan control, On-Command 2WD/4WD and differential-lock operation, and carburetor heating. Fault-finding also covers hard starting, poor idle and high-speed performance, shifting and clutch faults, overheating, poor braking, unstable handling, and lighting failures.

Specifications, Tools, and Diagrams

The manual supplies standard and service-limit tables for engine, chassis, and electrical components, plus component-specific torques, lubrication points, capacities, wear limits, carburetor settings, and test values. Special-tool listings use North American YM/YU/YS/YK/ACC numbers alongside the 90890-series numbers used outside the U.S. and Canada. Examples include the crankcase separating tool 90890-01135 / YU-01135-B, gear-lash measurement tool 90890-01467 / YM-01467, and sheave spring compressor 90890-04134 / YM-04134.

Useful drawings include the coolant flow diagrams, oil flow diagrams, cable-routing layouts, ignition-system circuit diagram, 2WD/4WD selecting-system circuit diagram, and the two-page YXR45FAV 2006 wiring diagram with component key and wire-color code. Exploded views and job charts identify parts, work order, lubrication points, locking agents, replacement items, and assembly notes at the start of removal and disassembly sections.

Several cautions can prevent expensive damage. The crankcase halves must be separated evenly and tapped only at reinforced areas; striking the mating faces can create sealing problems. The middle driven pinion gear must not be pressed directly on its threaded end, and its bearing retainers use left-hand threads. Front and rear knuckle bearings are installed by loading the outer race only; striking the center race or balls damages the bearing.

The separate 176-page YXR45FX Owner’s Manual, first edition July 2007, adds controls, On-Command four-wheel-drive and differential-lock operation, pre-operation checks, safe-use guidance, owner maintenance, troubleshooting charts, storage, specifications, maintenance records, and U.S. consumer information.

Safety note: Yamaha assumes the service-manual user already understands vehicle repair fundamentals. Brake work, working under a supported vehicle, rotating-driveline service, and electrical testing require training and equipment appropriate to the job.
