Arctic Cat 2007 2-Stroke Snowmobile Service Manual

This Arctic Cat factory service manual covers the listed 2007 2-stroke Bearcat, Panther, Z, Crossfire, F-Series, and M-Series snowmobiles. Separate procedures distinguish carbureted 370/570 machines from EFI 500/600/800/1000 applications, with model-specific LX, LXR, and Sno Pro information.

Service Text Search and Wiring Diagram Access

Search, bookmarks, and diagram detail: Main service text is searchable, with embedded bookmarks to the service sections and wiring diagrams. Some assembly illustrations and the wiring-diagram pages have no searchable labels. Small connector numbers and wire codes in the wiring diagrams require zooming.

One printable, English-language PDF contains 676 pages total: one opening contents page, 647 service-section pages, and 28 wiring-diagram pages, all included in that total.

Engine Overhaul, EFI Diagnosis, and Chassis Repair

The following selected topics highlight major repair areas rather than reproduce the complete contents. Other subjects include seasonal storage and preparation after storage.

• Engine repair: Step-by-step removal, crankcase disassembly, piston and cylinder inspection, reassembly, and installation, including in-chassis top-side service for Crossfire/M-Series engines.

• Fuel and oil injection: Carburetor overhaul, jetting and synchronization; EFI fuel-pressure, injector and throttle-body diagnosis; oil-pump bleeding, synchronization and output testing.

• Electrical troubleshooting: ECU/CCU codes, ignition tests, TPS checks, electric-start diagnosis, gauge/sender checks, and electronic reverse-control testing.

• Drivetrain and brakes: Drive-clutch and driven-pulley repair, ACT gear-case and chain-case service, reverse/non-reverse drivetrains, belt alignment and deflection, and hydraulic/mechanical brake work.

• Steering and suspension: Ski alignment, front-suspension, track and skid-frame repair, plus ACT, position-sensitive, Fox Air and Fox Zero Pro shock service.

• Workshop references: Assembly and cooling schematics, carburetor diagrams, diagnostic charts, exploded views, factory tool references, torque/clearance/wear data, and model-specific wiring diagrams.

Suited to technicians and experienced mechanics who can perform precision engine measurements and use the specified electrical test equipment.

Engine Inspection and Reassembly

Separate Crossfire/M-Series and F-Series chapters help match removal and installation procedures to the chassis. Crossfire/M-Series coverage also identifies top-side work that can be performed with the engine installed.

Internal measurements: Procedures address cylinder-head volume using the squish-gap method, cylinder trueness, piston-skirt clearance, ring end gap, piston-pin and bore condition, connecting-rod small-end bore, crankshaft runout, reed-stopper height, and reed-to-seat clearance. Engine-specific inspection data supports decisions about which components can be reused during an overhaul.

Assembly schematics show bolt patterns, seal direction, bearing-retaining points, and specified applications for Three Bond, High-Temp Sealant, anti-seize, and Loctite grades.

Connecting-rod, center-bearing, and oil-injection drive-gear work on the pressed crankshaft is referred to a qualified machine shop.

Cooling, APV, and Engine-Related Service

Coverage extends to axial-fan and belt service, water-pump rebuilding, crankcase pressure testing, liquid-cooling drain/fill procedures, and recoil starters.

Arctic Power Valve coverage includes cable adjustment, valve service, servo operation, and troubleshooting. The manual warns that incorrect exhaust-valve orientation can cause severe engine damage; the valves and gaskets have directional installation requirements.

Exhaust Controlled Timing coverage explains the nonadjustable system and provides an exhaust-temperature-sensor continuity check.

Carburetor, EFI, and Oil-Injection Diagnosis

Mikuni tuning references distinguish main jets, pilot jets, jet needles, needle jets, and piston valves. Carburetor troubleshooting separates rich and lean conditions by throttle opening, alongside cable and synchronization procedures.

EFI coverage addresses the fuel pump, regulator, injectors, throttle bodies, and sensors. No-start diagnosis distinguishes fuel delivery, ignition, and internal engine conditions before component replacement is considered.

Diagnostic-tool scope: Operating instructions for the 800/1000 cc laptop system and 500/600 cc EFI Analyzer are in separate companion manuals, P/N 2257-850 and 2259-020, which are not included. This service manual retains related self-diagnostic setup, code interpretation, component checks, fuel-pressure procedures, and peak-voltage specifications.

Oil-injection procedures distinguish cable-operated and control-rod systems, with separate bleeding instructions, pump-output tests, and check-valve testing.

Ignition, Control Units, and Chassis Circuits

The opening tables identify 11 Check Engine codes, 11 CCU wrench-icon codes, and two coolant-warning indications. Related tests address injectors, APV servomotors and potentiometers, knock sensors, stators, voltage outputs, tachometer signals, gear-position switches, and shift actuators.

Displacement-specific resistance and peak-voltage charts accompany ignition testing. The 1000 cc ignition-timing references distinguish Crossfire/F-Series from M-Series applications.

Chassis-electrical coverage includes brake-light and dimmer switches, rider and passenger warmer circuits, speedometer sensing, reverse alarms, and electronic shift controls.

Drivetrain, Brakes, Steering, and Suspension

Standard chain-case systems with and without reverse are separated from ACT Drive arrangements. F-Series and Crossfire/M-Series gear cases receive their own removal, internal inspection, assembly, and installation procedures. Calibration tables cover drive components, chains, sprockets, and altitude-related combinations.

The drive-clutch cautions explain how impact-tool tightening can damage the stationary sheave. Brake coverage distinguishes hydraulic assemblies from mechanical quick-adjust systems.

Steering and body: Procedures address steering posts, drag links, tie rods, spindles, suspension arms, sway bars, belly pans, tanks and seats, headlights, tunnels, bumpers, and body panels.

Rear suspension: A model-selection chart directs readers to four repair procedures for Z/LX, Bearcat/Panther, Crossfire/M-Series, and F-Series configurations. Supporting charts identify mounting locations, tracks, idler wheels, springs, skid-frame components, and shock valving.

Shock procedures include rebuilding, bleeding, nitrogen charging, and final checks. Fuel-system work requires separation from ignition sources; shock service involves high-pressure nitrogen, and running checks require secure support.

Schematics and Factory Tool References

Named references include the displacement-specific Engine Assembly Schematics, Engine Piston Travel Versus Crank Angle Chart, Crankshaft Runout/Repair Specifications drawing, F-Series and Crossfire/M-Series Cooling System Schematics, and carburetor schematics.

Separate ignition, main, hood, and handlebar harness drawings identify the relevant standard, LX, LXR, and Sno Pro configurations.

Tool references include Drive Clutch Pullers P/N 0644-207 and 0644-446, Flywheel Puller P/N 0744-040, and Piston Pin Puller P/N 0644-328. Other procedures specify Compression/Pressure Tester Kit P/N 0644-366, Fuel Pressure Test Kit P/N 0644-493, and Oil Seal Protector Tool P/N 0644-219.

A Preview of Piston Clearances and Thermostat Data

The engine table specifies piston skirt-to-cylinder clearance of 0.066–0.086 mm for the 370 cc engine and 0.085–0.115 mm for the 570 cc engine, illustrating the engine-specific measurement data supplied for internal inspection.

The liquid-cooled thermostat inspection specifies an opening temperature of 50°C (122°F). Its lock-open design means that allowing it to open fully during testing leaves it locked open and requires replacement.
