Arctic Cat F, Crossfire, M, Panther, Bearcat (370-1000cc Engines) Snowmobile 2008 Service Manual (P/N 2259-003, 2259-015)

This official 680-page OEM PDF is the factory shop manual for the 2008 Arctic Cat 2-stroke snowmobile range. Coverage includes Panther 370, Bearcat 570, F5, F 570, F6, F8, F1000, T500, T570, Crossfire 500/600/800/1000, and M6/M8/M1000 models, with Standard, LXR, and Sno Pro differences identified where the hardware or procedure changes. It covers the 370, 500, 570, 600, 800, and 1000 cc engine families; it is not the 2008 4-stroke manual.

• Engine repair coverage runs from removal and crankcase disassembly through cleaning, inspection, critical-component measurement, reassembly, installation, pressure testing, ignition-timing verification, and final operating checks.
• Model-specific engine-related service includes the 370 axial fan and belt, water pumps for the 500/600 and 800/1000 engines, liquid-cooling schematics, recoil starters, the Arctic Power Valve system, servomotor and cable checks, and Exhaust Controlled Timing diagnosis.
• Fuel-system chapters separate Mikuni carburetor repair and adjustment from EFI self-diagnostic codes, sensor and throttle-body testing, EFI Analyzer procedures, fuel-pressure diagnosis, and oil-injection pump bleeding, synchronization, output testing, and check-valve service.
• Drive and brake procedures distinguish standard chain-case and reverse assemblies from ACT gear-case and electronic-reverse systems, with clutch and driven-pulley repair, belt alignment and deflection, hydraulic brake service, bleeding, and troubleshooting.
• Five model-specific rear-suspension repair sections cover skid-frame removal, wear strips, rails, idlers, arms, springs, track tension and alignment, drive-sprocket location, and ACT, position-sensitive, Fox Air, and Fox Zero Pro shock service.
• Electrical coverage includes resistance and peak-voltage tests, CCU and EFI codes, ignition and timing sensors, electric start, reverse actuator, lighting, gauges, warmers, and appended full-page color harness schematics.

Engine and Fuel-System Repair

The engine chapters are divided by actual model and engine family rather than presented as one generic two-stroke procedure. Panther 370, Bearcat 570, F 570/T570, Crossfire/M-Series, and F-Series/T-Series applications receive their own removal, teardown, inspection, measuring, assembly, and installation sequences. Factory tables identify engine models AB37A1, AX50L7, AA56A7, AJ60L5, AB80L1, and AB10L2, then provide the related head-volume and squish references, piston and cylinder inspection limits, ring and pin data, connecting-rod measurements, crankshaft runout limits, APV settings, ignition timing, torque specifications, sealants, and locking-compound callouts.

The carbureted chapters include altitude- and temperature-based main-jet guidance, carburetor schematics, complete carburetor service, throttle and choke cable work, synchronization, and fuel-system fault charts. EFI coverage follows the ECU/CCU, injectors, fuel pump, throttle-position sensor, intake-air and coolant-temperature sensors, barometric-pressure and timing inputs, and the knock-sensor circuit where fitted. The manual also includes self-diagnostic codes, component voltage/resistance charts, fuel-pressure testing, throttle-body service, and oil-injection pump synchronization and usage tests.

Factory special-tool references include Drive Clutch Puller P/N 0644-207, Flywheel Puller P/N 0744-040, Piston Pin Puller P/N 0644-328, EFI Analyzer P/N 0644-476, Fuel Pressure Test Kit P/N 0644-493, and Laptop Diagnostic Tool P/N 0744-048.

The repair notes flag damage-critical details. The drive-clutch retaining bolt is hand-torqued rather than tightened with an impact tool because the stationary sheave can be damaged. Rear-suspension reassembly must also return the skid frame to the factory chassis and rail mounting locations; altered mounting points can damage shocks and suspension components.

Drivetrain, Chassis, and Electrical Reference

Drive-system data is organized by model, altitude, and hardware configuration. It covers clutch springs, cam arms and profiles, driven-pulley springs and helixes, drive belts, alignment bars, chain and sprocket combinations, chain-case performance calibrations, ACT gear-case ratios, drive-sprocket locations, lubricant and capacity specifications, and component-specific torque tables. Brake chapters cover the Panther 370 system plus Bearcat hydraulic and ACT brake layouts, including master-cylinder and caliper service and fault charts for drag, a spongy lever, oscillation, and loss of braking.

A servicing chart directs each model family to the correct rear-suspension repair procedure. Stock chassis and skid-frame mounting diagrams are provided for Panther, Bearcat, Crossfire, M-Series, F-Series, and T-Series machines, followed by track troubleshooting and rebuild information for the different shock designs. Steering and body coverage extends through steering posts, drag links, tie rods, spindles, ski alignment, suspension arms, sway bars, consoles, belly pans, gas tank and seat assemblies, tunnels, rear bumpers, snowflaps, headlights, and headlight aim.

The appended wiring sheets include the Bearcat 570 ignition harness, F5/F6/F8/F1000 ignition and main-harness layouts, Crossfire and M-Series ignition/main harnesses, the F 570/T570 main and hood harnesses, the Bearcat 570/Panther 370 hood harness, and model-group handlebar harness diagrams. These sheets complement the manual’s coil, regulator, sensor, CCU, starter, reverse-actuator, lighting, and warmer test procedures.

High-output ignition circuits, pressurized EFI fuel lines, rotating clutch and track assemblies, and nitrogen-charged shocks require proper shop controls. Follow the model-specific warnings, fastener torque, sealant, and locking-compound callouts before returning a repaired snowmobile to service.
