Vehicle Information
Polaris Long Track 440 Snowmobile (1983-1989)
The Polaris Long Track 440, produced from 1983 to 1989, was a robust utility snowmobile. It primarily featured a 432cc fan-cooled twin-cylinder engine, with some 433cc versions appearing in 1989. Designed for reliability and versatility, this model was a popular choice for winter work and recreation. While exact horsepower figures vary, similar engines from that era typically produced around 50 horsepower.
Over the years, the Long Track 440 saw notable evolutions. Engine model numbers changed, indicating internal revisions. By 1987, the "Long Track Reverse/Low Range" trim was introduced, offering reverse and a low range for enhanced utility. In 1988, the 432cc engine was improved to deliver 18% more power to its hi-low range transmission, also including reverse. The track length was generally 148 inches. Q: Is this product compatible with my Polaris Long Track 440?

Maintenance
| Component | Interval | Details |
| Engine Oil Filter | Not applicable | 2-stroke engines from this era do not use a conventional engine oil filter. Oil is either pre-mixed with fuel or injected directly. A fuel filter or oil injection line filter may exist and require inspection. |
| Drive Belt | Inspect before each ride and periodically. Replace every 1,600 to 3,200 km or every few seasons. | Check for wear, cracks, fraying, or glazing. Replace if any signs of damage are present or if performance degrades. |
| Spark Plug | Inspect/Clean annually or every 800 km. Replace annually or every 1,600 to 3,200 km. | Check for fouling, wear, or incorrect gap. Replace sooner if performance issues arise. |
| Air Filter | Inspect/Clean annually or every 800 km. | Check for cleanliness and obstructions. Clean or replace the filter element as needed, more frequently in dusty conditions. |
| Coolant | Inspect level before each ride and periodically. Inspect condition annually. Replace every 2-3 years. | This model is likely liquid-cooled. Check for clarity and proper freeze protection. Inspect hoses and clamps. |
| General Lubrication | Every 1,600 km or annually. | Grease suspension pivots, cables, and other fittings to ensure proper function and prevent wear. |
The maintenance intervals below are based on general practices for vintage 2-stroke snowmobiles. For precise recommendations, please consult your model's official owner's manual.
