2000 Bombardier DS 650 ATV Shop Manual (P/N 7404)

• Original 172-page OEM publication (PN 7404) documenting the 2000 Bombardier DS 650 all-terrain vehicle.
• Specific coverage for the 7404 model variant, detailing powertrain, chassis, and electrical system specifications.
• Provides comprehensive assembly diagrams for the Rotax 654 engine, cooling system, magneto, and transmission components.
• Serves as the primary first-edition reference used during the DS 650 launch, documenting exact maintenance intervals and performance parameters.

Engine and Technical Documentation

This section provides an in-depth review of the powertrain and chassis systems. Inside, the documentation details factory standards for engine removal, cylinder head service, and transmission teardowns. Mechanics will find the exact Rotax 654 engine configurations, including crankshaft alignment and clutch basket service metrics. The reference material also covers cooling system checks, like thermostat testing and water pump assembly. On the electrical side, diagnostics are supported by hard data, such as the charging system output of 280 W at 6000 RPM and precise CDI ignition specifications.

Maintenance and Specification Data

Detailed tables lay out standard torque values for 8.8 grade bolts, spanning from 1 Nm up to 150 Nm. The manual thoroughly documents service limits, noting a valve clearance of 0.10–0.15 mm and a maximum piston-to-cylinder clearance of 0.09 mm. Fluid capacity charts for the engine and cooling system complement the exact maintenance schedules defined for the 10, 25, 50, 100, and 200-hour service intervals. Working on high-performance ATVs carries inherent risks, so relying on factory-approved data and consulting a certified technician when handling critical powertrain components ensures safe workshop practices.
