Vehicle Information
Ski-Doo Valmont 440 Snowmobile (1972-1973)
The Ski-Doo Valmont 440, produced between 1972 and 1973, is an iconic snowmobile powered by a 436.6 cc two-cylinder engine. This model was known for its robustness and simplicity, delivering a consistent 28 horsepower. It was available in two primary trims: the Valmont 440R and the Valmont 440ER. While the core engine displacement and horsepower remained consistent, adjustments were made between 1972 and 1973. The fuel mixing ratio changed from 20:1 with regular Ski-Doo oil in 1972 to 40:1 with concentrated oil in 1973, requiring new carburetor calibration. The centrifugal governor also saw an update, and a 1973 supplement manual was issued to document these changes. FAQ:

Maintenance
| Component | Interval | Details |
| Engine oil filter | Not applicable | The two-stroke, two-cylinder engine uses a gasoline-oil pre-mix (20:1 in 1972, 40:1 in 1973) and does not have a traditional oil filter. |
| Drive belt | Inspect every 50 hours or as needed; replace every 2 400 to 4 800 km | Inspect regularly for wear or damage. Lifespan varies with usage. |
| Spark plug | Inspect and replace as needed, often annually | Regular maintenance item. Use a hotter plug for low-speed operation and the standard plug for high-speed use. |
| Air filter | Inspect and clean/replace as needed, before season and periodically | Visually check the filter's condition, especially before the start of the snowmobile season. |
| Coolant | Not applicable | The engine is air-cooled and does not use a liquid coolant system. |
Precise maintenance intervals for these vintage models are challenging to obtain. These recommendations are based on general practices and should be confirmed with the official shop manual if available.
