Suzuki LT-F250 Ozark 2WD Service Manual 2002–2014 (OEM)

• A 502-page PDF set — a 374-page Suzuki factory service manual for the LT-F250 Ozark 2WD, K2 through K9 (2002–2009), plus the 128-page 2009 LT-F250 Owner’s Manual, P/N 99011-05G57-03A.
• Covers engine removal and internal overhaul, including crankcase separation, top- and bottom-end teardown, cylinder-head and valve service, camshaft and cam-chain work, piston and crankshaft inspection, clutch repair, transmission inspection, and engine reassembly.
• Details the shaft-drive system from the secondary bevel gears and propeller shaft through the rear final drive and axle, with bearing and seal work, tooth-contact checks, backlash measurement, and shim-selection procedures.
• Walks through twin front-disc caliper and master-cylinder repair, brake-fluid replacement and bleeding, rear drum-brake service, front double-wishbone suspension, steering and toe-in, rear swingarm and shock, wheels, tires, and axle service.
• Provides carburetor and fuel-system work, engine-lubrication testing, and charging, starter, CDI ignition, battery, lamp, switch, and wiring troubleshooting.
• Includes K3–K9 model supplements, covering K4 clutch and drive-train changes, K5 brake and wiring updates, the distinct K6 E-04 three-forward-speed/electrical configuration, K7 brake-hose routing, the K8 silent-type cam chain, and K9 fuel-tank and carburetor revisions.

Factory Coverage and Model Identification

The service manual is built around the 2002 LT-F250K2, with nine core groups and seven factory supplements for K3 through K9. The general-information material identifies the serial-number location, country and area codes, approved fuel and lubricants, break-in procedures, information labels, and base specifications for the 246 cc air-cooled OHC single-cylinder engine.

Coverage distinguishes E-03 USA, E-33 California, E-28 Canada, E-24 Australia, and E-17 Sweden specifications. The K6 supplement also separates the E-04 configuration, which uses a three-forward-speed transmission rather than the standard five-forward setup. It adds speedometer/odometer, turn-signal, position-light, brake/tail-light, license-light, and switch circuits. Matching the model and area code matters before choosing transmission parts, electrical tests, or wiring information.

The factory chapters and supplements in this PDF explicitly identify K2 through K9. There are no L0–L4 supplement chapters for 2010–2014, so model-year-specific changes for those later machines should not be assumed to be documented.

Repair Depth Beyond Routine Maintenance

When you have an ATV on the lift, you need more than a maintenance checklist. The periodic-service group covers the air cleaner, valve clearance, spark plug, fuel hose, throttle cable, engine oil and filter, final-drive oil, spark arrester, clutch, brakes, steering, suspension, chassis fasteners, and general lubrication. It also provides compression-pressure and oil-pressure testing, plus clutch engagement and lock-up inspection.

From there, the manual moves into full repair work. Engine coverage includes removal and installation, cylinder-head disassembly, valve-guide and valve-seat servicing, camshaft and cam-chain inspection, cylinder and piston checks, crankshaft and connecting-rod inspection, clutch and starter-clutch service, transmission and shift-fork work, oil-pump service, recoil-starter repair, case splitting, and final assembly.

Separate chapters handle the Mikuni BS29 carburetor, fuel tank and valve, engine oil circuit, front and rear brakes, steering, suspension, swingarm, rear axle, charging system, starter system, ignition system, switches, lights, and battery. Symptom-based troubleshooting charts cover the engine, drive train, carburetor, chassis, brakes, electrical system, and battery.

The included K9 owner’s manual adds controls, loading, pre-ride inspection, routine maintenance, basic troubleshooting, winter operation, transporting, and cleaning. It is an operator and maintenance reference, not a substitute for the factory repair chapters.

Diagrams, Service Data, and Special Tools

Exploded assembly views show component order and identify the related torque, lubrication, sealant, and thread-lock points. Particularly useful references include the engine lubrication circuit and flow chart, full vehicle and area-specific wiring diagrams, and wiring-harness and cable-routing drawings. Fuel and carburetor hose routing, K7 front-brake-hose views, and exploded rear-drive, steering, and suspension assemblies add further workshop context.

The service-data sections provide component-specific torque tables, fluid-capacity data, inspection limits, clearances, shim information, carburetor settings, wheel and brake adjustment data, and electrical test specifications. Suzuki special tools are identified by part number, including the 09920-13120 crankcase separator, 09920-53730 clutch sleeve hub holder, 09915-64510 compression gauge set, and 09915-74511 oil-pressure gauge.

Rear-Drive Setup and Workshop Safety

Rear-drive setup is one area where the factory sequence matters: tooth contact, backlash, and shim thickness affect one another, and an incorrect setup can cause premature gear damage. The top-end section also calls out the risk of trapping the cam chain between the crankcase and cam-drive sprocket during cylinder and head assembly.

Support the ATV securely before wheel, suspension, swingarm, or rear-drive work. This manual is written for technicians and experienced owners with the proper service knowledge and specified tools; incorrect repair work can leave the machine unsafe to operate.
