• Official OEM factory publication (P/N 61800-HN7-A00, May 2000 edition) covering the 2001–2003 Honda Rubicon 500 and TRX500FA.
• Spans 408 pages of exhaustive technical specifications, maintenance schedules, and system illustrations.
• Provides precise factory calibration data specifically for the unique longitudinal engine architecture.

Manual Contents and System Diagnostics

Getting accurate factory data is critical when working on early 2000s Rubicons. This publication delivers exactly what you need for complete system-level diagnostics and maintenance. It thoroughly documents the liquid-cooled engine internals, fuel delivery components, and frame assemblies. You also get dedicated sections breaking down the proprietary Hondamatic automatic transmission, detailing the centrifugal clutch, starter clutch, and sub-transmission mechanisms.

Working with high-torque drivetrain parts and complex hydraulic systems requires strict adherence to factory safety protocols. This reference outlines those critical precautions right alongside the procedural documentation. Beyond the powertrain, the guide covers essential chassis elements like steering geometry, front and rear suspension, and braking systems. For electrical troubleshooting, it maps out full wiring schematics, charging system outputs, and ignition timing.

Specification Highlights

Mechanics rely on exact numbers to get the job done right. This document is packed with extensive tolerance charts, fluid capacities, and fastener torque values to keep the ATV performing to factory standards. For instance, cylinder compression is explicitly listed at 608–902 kPa at 450 rpm. It notes a 1.7-liter cooling system capacity across the radiator and engine, requiring a minimum thermostat valve lift of 8 mm.

When reassembling components, the book gives you the exact torque figures you need, such as 53 Nm for the cylinder head cover cap nut and 78 Nm for the front wheel hub nut. Sensor reference values help isolate electrical faults fast, while the maintenance schedules specify exact intervals for fluid changes and wear-part inspections.
