Vehicle Information
Moto-Ski Chimo 440 Snowmobile (1974-1975)
The Moto-Ski Chimo 440, produced for the 1974 and 1975 model years, was a robust fan-cooled snowmobile designed for versatility, replacing the Zephyr/MS-18 in the lineup. It was built on a stretched Futura chassis, earning its reputation as a "go anywhere" machine. Both years featured a 440cc BSE fan-cooled engine. A significant update occurred in 1974, where the 440T engine was re-engineered with a 6-port design, boosting its horsepower from 33 HP to 40 HP. This 40 HP output is inferred to have carried over to the 1975 model. The 1975 model year was transitional for Moto-Ski, with many models shifting to Rotax engines, but the Chimo 440 notably retained its BSE engine. No distinct trim levels were offered for the Chimo 440 during these specific years. FAQ:

Maintenance
| Component | Interval | Details |
| Lubrication (Drive Chain, Front Axle, Driven Pulley, Steering) | Every 25 hours of operation | Drive chain (10 oz of Moto-Ski Special Grease), Front axle (lubricate until new grease emerges), Driven pulley (2-3 shots of Moto-Ski grease into the bolt hole), Steering mechanism (a few drops of oil on the ball joints and nylon bushings). |
| Drive Belt | Check regularly | Look for cracks, fraying, or uneven wear. Replace if width is less than 25 mm. Abnormal wear often indicates misalignment. |
| Chain Case Components | Check condition and adjust tension if necessary | Check chain, sprockets, and seals. Replace defective ones. |
| Spark Plugs | Check condition regularly and replace as needed | No specific replacement interval. Clean, re-gap, and test if fouled. |
| Fuel System | Check for clogging | For summer storage: disconnect fuel lines, empty and rinse the fuel tank, then run the engine until it stops to dry out the carburetor. |
| Air Filter | Annually or every 50-100 hours | Inspect and clean/replace. For fan-cooled engines, typically foam or mesh. |
| Oil Filter | Not applicable | 2-stroke engine, oil is mixed with the fuel. |
| Coolant | Not applicable | Fan-cooled engine, no liquid coolant system. |
