Honda TRX350 Rancher & Rancher 4x4 (TM/TE/FM/FE Series) ATV Service Manual - Complete Guide for Maintenance and Troubleshooting (2000-2003)

Honda TRX350 Rancher Service Manual - 2000-2003

This factory-authorized service manual provides the definitive engineering framework for the maintenance and repair of the TRX350 series. It features a critical dry sump lubrication system specification, requiring exactly 1.95 liters of oil after a standard drain to prevent crankcase pressure imbalances and ensure long-term engine life. Technical noun-based procedures and specific action sequences guide the technician through every facet of vehicle restoration and uptime management.

Technical Applicability & Chassis Configurations: 2WD vs. 4WD

• TRX350TM/TE Series (2WD Configuration): Covers the rear-wheel-drive generations utilizing either the left-foot operated return system (TM) or the hand-operated Electric Shift Program (TE).
• TRX350FM/FE Series (4WD Configuration): Covers the four-wheel-drive generations equipped with the A.P. Suretrac torque-biasing front differential and either manual foot-shift (FM) or Electric Shift Program (FE) transmissions.
• Serial Number Identification: Primary machine identification is conducted via the Vehicle Identification Number (VIN) located on the left side frame down tube and the Engine Serial Number stamped on the left side of the rear crankcase.

Operational Success & Performance Benchmarks

• Transmission Precision: Detailed troubleshooting for the Electric Shift Program (ESP) ensures gearshift motor calibration and angle sensor accuracy to prevent transmission jumping or hard shifting.
• Safety Compliance: Exhaust emission control system data ensures compliance with California Air Resources Board (CARB) standards through precise lean carburetor settings.
• Parts Accuracy Mapping: Component removal charts and assembly illustrations eliminate guesswork during complex frame and body panel teardowns.

Document Metadata

• Manufacturer: Honda Motor Co., Ltd.
• Document Type: Service Manual (Shop/Workshop)
• Engine Type: 329.1 cm³ (20.08 cu-in) Single Cylinder OHV
• Manual Capacity: 25 Specialized Sections including Technical Features.

Technical Depth & Factory Benchmarks

• Cylinder Compression: Standard compression is rated at 667 kPa (97 psi) at 450 rpm to verify top-end health.
• Valve Architecture: Intake and exhaust valve clearances must be set to exactly 0.15 mm (0.006 in) while the engine is cold.
• Fuel Metering: Carburetor (VE94A) factory settings include a #130 main jet and a float level of 18.5 mm (0.73 in) for optimal stoichiometric performance.

Visual Navigation Aids & System Schematics
