• Covers all 1995–2003 Honda Fourtrax Foreman 400 (TRX400FW) ATV models
• Genuine OEM factory publication featuring 370 pages of technical specs for the 394.9 cc air-cooled engine
• Speeds up workshop diagnostics with high-resolution exploded-view diagrams, electrical schematics, and accurate torque values

Contents Overview

This factory publication breaks down the TRX400FW across 24 chapters. It delivers detailed documentation for the engine, chassis, and electrical systems. Starting with general safety and model identification, the guide moves straight into heavy mechanical details. You get component specifications from the ground up. This covers engine removal, cylinder head teardowns, piston assembly, and transmission mechanics. Need chassis data? Dedicated sections outline the suspension, steering, front and rear drive mechanisms, and brakes. Finally, the electrical chapters round out the publication with full wiring diagrams and starter system benchmarks.

Technical Data Preview

The reference includes factory-verified tables for fluid capacities, mechanical clearances, and torque values to support daily workshop routines. For example, cylinder compression is rated at 1,226–1,442 kPa (12.5–14.5 kg/cm²) without the decompressor activated. Engine oil capacity requires 2.0 liters for a standard drain. This bumps up to 2.1 liters if you swap the filter. The front and rear final reduction gears specify Hypoid gear oil SAE #80, while valve clearance for both intake and exhaust sits tightly at 0.15 mm (0.006 in). Keep in mind that while these factory specifications provide an exact reference baseline, tackling heavy ATV maintenance carries inherent risks. Always consult a certified powersports technician if you are unsure about safe servicing procedures.
