Vehicle Information
Ski-Doo Alpine 640 Snowmobile (1969-1982)
The Ski-Doo Alpine 640, produced from 1969 to 1982, was a robust utility workhorse, renowned for its reliability. It was consistently powered by a 635.1cc (often rounded to 640cc) twin-cylinder Rotax engine, primarily fan-cooled. This engine demonstrated reliable performance for demanding tasks. While the core engine remained consistent, some nuances were observed over the years. Horsepower decreased from 40 hp in 1969 to 35 hp from 1970 to 1972. Some 1972 models were also equipped with a dual carburetor setup, potentially offering enhanced performance. The "ER" designation (Electric Start and Reverse) became a standard or widely available option early in the model's history, as seen in trims like the Alpine 640 ER, Alpine Invader 640/ER, and Valmont 640E/ER.

Maintenance
| Component | Interval | Details |
| Engine Break-in Period | 10 to 15 operating hours | Use a richer fuel mixture (e.g., 40:1). Avoid prolonged wide-open throttle. A dealer inspection is suggested after 10 hours or 30 days. |
| Steering and Suspension Lubrication | Monthly or every 40 hours | More frequently if used in wet snow or severe conditions. |
| Chaincase Fluid Level | Pre-season and every 50 hours | |
| Chaincase Oil Change | Annually or at end of season | Use manufacturer-specified chaincase oil. |
| Drive Belt | Inspect every 50 hours or if performance changes | Expected lifespan: 2,400 to 4,800 km. Clean belt dust buildup annually or when performance degrades. |
| Fuel/Oil Mixture (2-stroke engine) | Every refueling | Crucial to prevent engine damage. After break-in, recommended 50:1 mixture. Some 1972 models may use 20:1, and 40:1 with concentrated Ski-Doo oil. Mix in a separate container. |
Maintenance intervals may vary. It is highly recommended to consult the official owner's or service manual for your specific model year for precise information.
