2006 Arctic Cat ATV 250 DVX & Utility Model Service Manual

• Factory service manual for the 2006 Arctic Cat ATV 250 DVX and Utility models, supplied as a 146-page PDF and dated May 2006.
• Covers engine/transmission removal and installation, top-end repair, crankcase separation, crankshaft and balancer inspection, and model-specific transmission disassembly and reassembly.
• Details the V-belt drive, drive pulley, driven pulley/centrifugal clutch, and Utility recoil starter, with inspection limits and assembly checks.
• Separates the DVX chain-drive rear axle from the Utility driveshaft, bevel-gear, rear gearcase, and swing-arm layout, including axle, bearing, seal, and gearcase work.
• Includes Keihin PTG-22 carburetor service, oil- and water-pump repair, cooling-system testing, brake bleeding and pad burnishing, suspension service, and steering alignment.
• Provides component-level electrical test routines and symptom-based troubleshooting charts for engine, drive, fuel, electrical, steering/suspension, and brake faults.

Model and Workshop Scope

This manual keeps the shared 250 platform in one workshop reference while separating DVX and Utility specifications and procedures where the machines differ. Coverage is defined by model year and configuration rather than a serial-number range. Written for service personnel, it is best suited to technicians and experienced mechanics equipped for precision measurement, electrical testing, engine lifting, and spring-loaded clutch work.

Engine, V-Belt Drive, and Transmission Repair

The engine chapter is organized as a complete removal, teardown, inspection, reassembly, and installation path. Top-side, left-side, and right-side components can be serviced in the frame; center crankcase work requires engine/transmission removal. Coverage includes the cylinder head, valves, camshaft, piston and rings, cylinder, crankshaft, balancer shaft, oil pump, rotor/flywheel, stator, trigger coil, drive pulley, and driven pulley/centrifugal clutch.

Transmission repair is configuration-specific. The DVX section covers the main shaft, countershaft, primary drive axle, shift cam, and shift fork. The Utility section adds high, low, and reverse gearing, drive and driven bevel gears, the secondary driven bevel-gear assembly, driveshaft, universal joint, and rear gearcase.

Fuel, Cooling, Electrical, and Chassis Work

Fuel and cooling chapters cover carburetor removal and rebuild, float inspection, gas-tank and valve service, oil-flow reference and oil-pump service, radiator removal, thermostat and fan testing, and water-pump seal and impeller repair. Chassis procedures include hydraulic-brake bleeding, front and rear pad replacement, pad burnishing, master-cylinder replacement, shock and A-arm inspection, swing-arm bearing service, steering-post and tie-rod repair, and toe-in/toe-out adjustment.

Electrical diagnosis uses voltage, resistance, continuity, and peak-voltage checks for the ignition coil, magneto/stator, coolant and fan switches, starter circuit, CDI, regulator/rectifier, relays, switches, lights, and LCD gauge. The troubleshooting section uses condition-to-remedy tables to isolate faults across the covered systems.

Factory Tools, Schematics, and Specifications

Named service tools include the Valve Clearance Adjuster p/n 0444-178, Compression Gauge p/n 0644-376, Piston Pin Puller p/n 0644-328, Spanner Wrench p/n 0444-153, Crankcase Separator/Crankshaft Remover p/n 0444-009, and Pivot Lock Nut Wrench p/n 0444-201. Electrical testing specifies the Fluke Model 73 Multimeter p/n 0644-191 with Peak Voltage Reading Adapter p/n 0644-307.

Visual references include the Carburetor Schematic, Oil Flow Chart, DVX and Utility Rear Drive Assembly Schematics, and model-specific Front and Rear Suspension Assembly Schematics. Separate Utility and DVX torque tables are backed by engine, clutch, transmission, electrical, cooling, brake, and chassis test values, clearances, wear limits, capacities, and adjustment specificatio
