2013 Yamaha WR250F(D) Owner's Service Manual PDF (P/N 1HC-28199-52-E0)

The 2013 Yamaha WR250F(D) Owner's Service Manual, 1HC-28199-52-E0, is the first edition dated April 2012. It covers USA, CDN, AUS, NZ, Europe, and ZA configurations.

• Engine repair: Engine removal, cylinder-head and titanium-valve service, camshaft timing, piston inspection, and crankcase separation, with exploded diagrams and job instruction charts.

• Clutch and transmission: Clutch overhaul, shift-fork and shift-cam inspection, kick-shaft service, and AC magneto and starter-clutch removal.

• Fuel and cooling systems: FCR-MX37 carburetor disassembly, accelerator-pump adjustment, air-induction checks, cooling-system pressure testing, and water-pump repair.

• Brakes and suspension: Hydraulic brake bleeding, caliper and master-cylinder overhaul, front-fork rebuilding, and rear-shock spring and bearing service.

• Electrical diagnosis: Wiring diagrams and fault charts for ignition, electric starting, charging, throttle-position sensor, lighting, and speedometer circuits.

• Maintenance references: Break-in guidance, periodic maintenance charts, component-specific torque tables, lubrication diagrams, and cable-routing diagrams.

The engine, chassis, and electrical repair chapters are intended for readers with existing Yamaha servicing knowledge and skills.

Maintenance Schedules and Carburetor Tuning

Canada-specific emission-control and lubrication schedules are separate from the competition-use maintenance schedule. The engine-tuning chapter expressly excludes Canada, and the carburetor specifications distinguish European settings from those for the other markets.

The FCR-MX37 section goes beyond jet identification to float-height checks, accelerator-pump timing, and hot-start plunger and air-cut valve inspection. Its symptom-based setting chart relates running problems to the relevant carburetor adjustments and checks.

Engine, Clutch and Cooling Repair

Intake and exhaust valve pad-selection tables relate measured clearance to the installed pad number, helping identify a replacement shim for a valve adjustment. Camshaft inspection also covers the decompression mechanism and timing-chain tensioner.

The cylinder-head section addresses titanium valves and their replacement requirements after lapping. Camshaft-cap cautions explain how uneven tightening can damage the head, caps, and camshafts.

Clutch inspection data distinguish friction-plate wear from clutch-plate warpage. Torque tables cover engine mounts, chassis fasteners, and brake assemblies.

Cooling coverage includes radiator-cap testing and water-pump shaft, bearing, and seal inspection. Oil-pump clearance checks and lubrication diagrams document the engine's oil circuit.

Suspension and Brake Service

Front-fork procedures specify the damper rod holder YM-01494 / 90890-01494 and fork seal driver YM-A0948 / 90890-01502. Assembly cautions describe how a dropped damper rod can damage the internal valve.

Suspension setting charts connect handling symptoms with spring and damping adjustments. Rear-shock coverage includes removal, spring replacement, and bearing work. Brake exploded views distinguish front and rear caliper and master-cylinder assemblies.

Follow the manual's precautions for flammable fuel and high-pressure nitrogen. Yamaha expressly warns against disassembling the rear-shock cylinder or reservoir.

Ignition, Starting and Charging Diagnostics

System-specific inspection charts cover no-spark, no-crank, and charging faults. The starting-circuit cut-off diagram shows the clutch and neutral interlocks, while connector views and wire-color codes support electrical fault tracing.

Reference data include market-specific CDI unit identification, AC magneto coil resistance, and battery charging checks. Throttle-position sensor replacement and adjustment are documented alongside speed-sensor and multi-function display tests.

Sample Valve-Clearance, Ignition and Coolant Data

Selected data from the engine, electrical, and cooling sections illustrate a small part of the manual's specifications. Intake valve clearance is 0.10–0.15 mm with the engine cold.

The ignition-coil secondary resistance specification is 4.6–6.8 kΩ at 20 °C (68 °F).

The coolant capacity table lists 0.99 L for the system, including all coolant routes.

PDF Navigation and Included Pages

Text search and wiring detail: Body text is searchable, but some chart and diagram text is not. Section bookmarks lead to individual topics; chapter-level bookmarks return to the contents page. Small wire-color and connector labels require zooming.

One printable 232-page PDF: 220 English technical chapter pages, 10 front-matter pages (including two multilingual opening pages), one blank closing page, and one back cover. All of these pages are included in the total.
