Description
Bred from a rich history of experienced belt builders, the Dayco XTX belt is specifically engineered to maximize the performance of the most extreme, high horsepower snowmobiles. Beating the competition on the race course is just one of many aspects that sets the XTX belt apart from its competition. Specially formulated high temperature Polymer along with the highest level of engineered reinforcement proves to perform better in belt operating temperature and efficiency than leading competitors. Its innovative break-through design of deeper cogs on top and rounded cogs on the bottom yield the advantages of ultimate flexibility and longer belt life while being a better alternative to the original equipment belt.

| Spark Plugs | Inspection: 250 km, 800 km, 1 600 km. Replacement: every 1 600 km or as needed. | Inspect electrodes for wear and carbon buildup, adjust gap if needed (0.7 mm). |
| Air Filter | Pre-filter: inspect and clean often/daily. Main element: inspect weekly. Replacement as needed. | Periodically clean intake foam filters, especially when operating in loose powder snow. General guidelines suggest replacement every 100 hours, 1 600 km, or yearly. |
| Coolant | Level check: daily. Replacement: every 5 years (extended life coolant) or every 2 years (other types). | Check level during pre-ride inspections. General recommendation is to change coolant every two years. |
