• Covers the 2005–2013 Honda Recon TRX250TM (manual foot-shift) and TRX250TE (Electric Shift Program) ATVs.
• Official OEM technical publication (P/N 61LW030).
• Documents the 61LW030 series build with over 375 pages of factory specifications, tolerances, and wiring schematics.
• Provides step-by-step procedures for component overhauls, transmission teardowns, brake bleeding, and comprehensive troubleshooting.
• Details the centrifugal clutch, rear driving mechanism, crankcase, steering system, and alternator assemblies.

Technical Details and Data

Engineers and mechanics working on the Honda Recon series need accurate factory numbers to get the job done right. This original Honda PDF publication delivers exactly that for the shop floor. It outlines the 229.2 cm3 air-cooled engine, detailing the 9.2:1 compression ratio and valve clearances set at a strict 0.13 mm for both intake and exhaust. Need to know the final gear case oil capacity? It holds exactly 80 cm3 after draining. The transmission section covers the 5-speed constant-mesh gearbox with reverse. You will also find electrical baselines, such as the 0.8–0.9 mm spark plug gap and complete testing protocols for the AC-CDI ignition system. To quickly trace faults, the manual includes specific visual aids like lubrication system diagrams, cable and harness routing views, gear tooth contact pattern charts, electrical system diagrams, and troubleshooting flowcharts.

Maintenance and Component Highlights

Beyond the engine block, this book breaks down chassis and suspension geometries. It maps out the double-cradle frame and front double wishbone suspension, alongside exact specifications for the hydraulic drum brakes. For example, the front brake drum has a standard inner diameter of 130.0 mm, bottoming out at a service limit of 131.0 mm. Fuel system tuning gets highly specific, noting the initial pilot screw setting for the PDC1F carburetor at 1-1/2 turns out. Proper torque is essential when buttoning up these machines. You'll find specific bolt-tightening values throughout the documentation, like 25 N-m for the oil drain plug and 23 N-m for the exhaust muffler band bolt.

Instead of sending ATVs to the dealership for complex Electric Shift Program (ESP) failures or complete crankcase separation, mechanics can keep the work in-house to maximize shop profitability. You will find precise step-by-step walkthroughs for complete carburetor rebuilds, brake fluid bleeding, and centrifugal clutch replacements—tasks that would otherwise require an expensive workshop visit. When tackling advanced heavy procedures, technicians must be aware of specific material tolerances and design quirks. For instance, when extracting final drive case bearings, the aluminum gear case cover must be heated uniformly to 80°C (176°F); the manual notes that using a concentrated open flame torch will easily cause irreversible metal warpage. Furthermore, when disassembling the centrifugal clutch, the lock nut utilizes left-hand threads—a critical detail that routinely catches DIYers off guard and leads to stripped drivetrain components.

Keep in mind that working on ATVs involves heavy machinery, moving parts, and combustible fluids. Always refer directly to the detailed factory procedures inside this original documentation to ensure safe, reliable repairs.
