Arctic Cat DVX 250 & Utility 250 ATV Service Manual (2007)

Built around the different service requirements of the Arctic Cat DVX 250 and Utility 250, this 2007 service manual covers routine maintenance, fault diagnosis, major engine work, drivetrain repair, and chassis service.

Engine Repair, Model-Specific Drivetrains, and Electrical Tests

The following highlights are selected coverage, rather than a complete contents list. Other topics include storage preparation and headlight bulb replacement.

• Model-specific drivetrains: Separate DVX transmission and chain-driven rear-axle procedures, plus Utility transmission, secondary bevel drive, driveshaft, universal joint, rear gearcase, and recoil-starter service.

• Engine repair: Step-by-step removal and installation, top-side and side-cover disassembly, crankcase separation and joining, and inspection of internal engine components.

• Fuel, lubrication, and cooling: Keihin carburetor disassembly and inspection, throttle and idle adjustment, fuel-tank and valve service, oil-pump inspection, radiator service, thermostat testing, and water-pump repair.

• Electrical diagnosis: Resistance, continuity, voltage, and peak-voltage tests for ignition and charging components, starter circuits, relays, switches, lighting, and instruments.

• Chassis and brakes: Swing-arm and cushion-link service, A-arm and wheel-hub inspection, shock removal, rear spring-preload adjustment, steering alignment, brake bleeding, pad replacement, and master-cylinder replacement.

• Workshop reference data: Separate DVX and Utility torque tables, periodic maintenance requirements, fluid capacities, wear limits, clearance specifications, electrical test values, and condition/remedy troubleshooting charts.

The procedures assume familiarity with wear measurement, pullers, and electrical test equipment, making this manual best suited to professional mechanics or experienced, well-equipped DIY owners.

Engine Inspection and Assembly

The engine/transmission chapter identifies which top-side, left-side, and right-side jobs can be performed with the power unit still in the frame. Center-crankcase service requires engine removal, helping you plan the extent of disassembly before starting a repair.

Component-level inspection covers valve seats and guides, camshaft and rocker parts, piston and rings, cylinder bore, crankshaft runout, balancer shaft, oil pump, V-belt pulleys, centrifugal clutch, and transmission assemblies. Reassembly coverage includes cam-chain timing, tensioner installation, and balancer timing.

Assembly cautions: Incorrect V-belt positioning at the drive-face splines can leave the pulley improperly secured and damage the drive sheave or crankshaft. Incorrect piston-ring orientation or forcing the cylinder over the piston can damage the piston, rings, cylinder, or crankshaft assembly.

DVX and Utility Drivetrain Differences

The DVX repair path covers its output sprocket, drive chain, axle housing, bearings, and brake disc. Its axle-nut tightening arrangement uses a special torque-wrench adapter and a calculated wrench setting.

Utility procedures follow the universal joint, driveshaft spring, swing-arm-mounted axle, and secondary bevel gears. Internal transmission work addresses the high/low/reverse gears, clutch dogs, shift forks, shafts, bearings, seals, and cases.

Rear gearcase scope: The Utility final-drive gearcase is checked for smooth operation; a noisy or binding assembly is replaced rather than internally rebuilt under these procedures.

Carburetor, Lubrication, and Cooling Work

The Keihin PTG-22 coverage includes jet and needle inspection, float-height checking, diaphragm inspection, cleaning, and reassembly. Cooling-system procedures cover hoses, fan removal, thermostat operation, and water-pump mechanical and drive-seal replacement.

Oil-pump disassembly and inspection are included, but a defective pump is replaced as an assembly. The oil-flow chart shows the lubrication circuit alongside the component procedures.

Electrical Tests and Instrument Checks

The electrical chapter distinguishes harness-side checks from component tests. Coverage includes the ignition coil, magneto coils, CDI checks, regulator/rectifier, starter motor and relay, start-in-gear relay, temperature and fan switches, handlebar controls, indicator lights, and LCD gauge.

The manual also explains that RPM-limiter operation can resemble a high-speed misfire. Starter-motor and LCD-gauge coverage centers on diagnosis and assembly replacement.

Electrical illustrations include connector-side test views and instrument callouts. A full-machine wiring diagram is not included in this PDF.

Illustrations, Tools, and Service Limits

Reference illustrations include the carburetor schematic, oil-flow chart, separate DVX and Utility rear-drive assembly schematics, and front and rear suspension assembly schematics.

Mechanical tool references include the Valve Clearance Adjuster P/N 0444-178, Compression Gauge P/N 0644-376, Piston Pin Puller P/N 0644-328, and Crankcase Separator/Crankshaft Remover P/N 0444-009. Electrical testing specifies the Fluke Model 73 Multimeter P/N 0644-191 and Peak Voltage Reading Adapter P/N 0644-307.

Parts and brake scope: Part-number, quantity, and application lookup is directed to the separate Illustrated Parts Manual. Both brake master cylinders are treated as non-serviceable assemblies requiring replacement.

Follow the manual's warnings when lifting or supporting the ATV, servicing hydraulic brakes, testing live electrical circuits, or working around fuel and hot cooling-system components. Advanced engine, transmission, and brake work requires the specified tools, suitable shop equipment, and the skill to verify the completed repair safely.

Carburetor and Clutch Inspection Examples

For both models, the carburetor specifications list a float-arm height of 14.8 mm (0.58 in.). The checking procedure places the carburetor on its side with the float contacting the needle valve.

The centrifugal-clutch inspection specifies a minimum shoe-lining service limit of 0.5 mm (0.020 in.). The manual calls for replacement of the complete shoe set if any lining is below that limit.
