2007–2009 Yamaha YFM7GPW Grizzly 700 FI Owner's Manual (P/N LIT-11616-20–11)

Use the Yamaha documentation written for the 2007 Grizzly 700 FI YFM7FGPW, including the 3B41, 3B45, and 3B48 model-code variants and the machine’s electric power steering system. The PDF package contains two Yamaha Motor Corporation publications: the 485-page Service Manual, P/N LIT-11616-20-11 (First Edition, May 2006) and the 183-page Owner’s Manual, P/N LIT-11626-20-11 (1st edition, April 2006). This is model-specific 2007 YFM7FGPW coverage; later Grizzly 700 model suffixes require their matching publications.

• Engine, CVT, and transmission repair: Covers engine removal and installation; cylinder head, camshaft, rocker arm, valve, cylinder, and piston work; crankcase and crankshaft service; oil-pump inspection; primary and secondary sheave service; clutch repair; transmission inspection; and middle-gear backlash setup.
• Fuel-injection and EPS diagnostics: Includes ECU and EPS self-diagnostic tables, diagnostic modes, fault-code troubleshooting, sensor and actuator checks, fuel-pressure testing, throttle-position sensor adjustment, EPS motor checks, and EPS torque-sensor testing.
• On-Command drivetrain service: Details front CV joints and differential repair, rear CV joints and final-drive service, differential and final-gear lash measurement, shim selection, thrust-clearance checks, and 2WD/4WD/differential-lock electrical diagnosis.
• Brake, steering, and suspension repair: Covers hydraulic brake bleeding, master-cylinder and caliper disassembly, pad and disc inspection, wheel and hub service, steering-stem and tie-rod work, knuckle and ball-joint inspection, toe-in adjustment, front and rear arms, the stabilizer, and shock absorbers.
• Electrical diagrams and workshop views: Provides ignition, starting, charging, lighting, signaling, cooling-system, fuel-pump, 2WD/4WD, and EPS circuit diagrams, plus oil-flow and coolant-flow diagrams, cable-routing drawings, exploded assembly views, and the complete YFM7FGPW 2007 wiring diagram.

Factory Repair Coverage

The service manual follows Yamaha’s exploded-diagram and job-chart format. Removal and disassembly sequences identify parts in order, while the accompanying repair sections add inspection criteria, assembly notes, lubrication points, replacement requirements, tightening torques, wear limits, clearances, and electrical test data. The engine chapters continue well beyond routine maintenance, covering valve and guide inspection, piston and ring checks, starter clutch and torque limiter testing, balancer and oil-pump drives, sheave and clutch service, crankcase separation, transmission reassembly, and middle-gear shim selection.

The special-tool section gives Yamaha and U.S./Canadian tool numbers rather than leaving major jobs to improvised equipment. Examples include the crankcase separator 90890-01135 / YU-01135-B, gear-lash measurement tool 90890-01475 / YM-01475, sheave spring compressor 90890-04134 / YM-04134, and fuel-pressure gauge 90890-03153 / YU-03153 with adapter 90890-03176 / YM-03176. Valve-service tools, flywheel and piston-pin pullers, ball-joint tools, bearing drivers, electrical testers, and the specified Yamaha crankcase sealant are also identified.

Diagnostics, Schematics, and Specifications

The owner’s manual explains the multifunction display and when a two-digit error code appears. The service manual supplies the ECU self-diagnostic function table, diagnostic mode, diagnostic code table, sensor-operation and actuator-operation tables, and fault-specific troubleshooting. It also covers the intake-air pressure and temperature sensors, fuel injector testing, fuel-pump and pressure-regulator operation, and throttle-position sensor checking and adjustment. The EPS section separately explains normal warning-light behavior, control-unit self-diagnosis, diagnostic mode, fault tables, EPS motor testing, and torque-sensor checks.

Diagram support includes the FI system circuit diagram, EPS system block and circuit diagrams, coolant-flow and oil-flow diagrams, system-specific electrical circuits, cable-routing drawings, and the 2007 wiring schematic with component and wire-color keys. Specifications are organized into general, engine, chassis, and electrical categories, followed by engine and chassis torque tables, lubricant listings, fluid capacities, inspection limits, clearances, and adjustment data.

Owner Operation and Maintenance Reference

The owner’s manual covers the On-Command 2WD/4WD and differential-lock controls, multifunction display, drive-select operation, reverse use, engine break-in, loading and accessory limits, and the factory pre-operation checklist. Its maintenance section includes the emission-control maintenance chart and the general maintenance and lubrication chart, along with owner procedures for engine oil and filter service, final and differential gear oil, coolant, air-filter and spark-arrester cleaning, brake inspection, battery and fuse service, lighting, wheels, and basic troubleshooting charts.

Factory specifications in the owner’s manual include fluid-capacity data, approved lubricants, tire sizes and pressures, maximum load ratings, brake and chassis data, and auxiliary DC-jack limits. The riding chapters also address hills, slopes, shallow-water crossings, rough terrain, sliding, skidding, and recovery from a stall or rollback.

Model-Specific Repair Notes

The cylinder-head section warns against turning the crankshaft while the camshaft sprocket is being installed; losing the specified index can produce improper valve timing and engine damage. In the differential chapter, the factory-assembled gear unit is not meant to be split, the gear-motor check does not use 12-volt battery power, and the temporary ring-gear holding bolt is only finger-tight—ignoring those limits can damage the gearset or leave the 2WD/differential-lock indication out of index. The brake chapters caution against operating a lever or pedal with its caliper removed because the pads will be driven shut.

The service manual was written for Yamaha dealers and qualified mechanics and assumes a working knowledge of vehicle repair. Securely support the ATV, isolate the electrical system as directed, and observe the manual’s warnings for brake fluid, spring-loaded sheave components, hot coolant, fuel, and rotating assemblies before beginning repair work.
