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.
Key Features
- Faster and more consistent throttle response at high speeds
- Quicker throttle response at mid-speed acceleration
- Greater secondary acceleration at high RPMs
- Greater secondary acceleration as primary acceleration increases
- Reduction in slippage during the highest levels of torque
- Providing more power to track
- Better performance during deceleration (more responsive engine braking)
- Tested and proven reliability at well over 12,000 RPMs
- Cooler-running temperature than the leading competitors
Technical Specifications
- MFG. Part Number XTX5057
Vehicle Information
Arctic Cat ZR 500 Snowmobile (1998-2002)
The Arctic Cat ZR 500, a high-performance snowmobile produced from 1998 to 2002, was renowned for its agile handling and race-inspired chassis. Throughout these years, it was powered by a consistent 497cc (or 493cc) liquid-cooled twin-cylinder engine, known for its snappy acceleration and crisp performance. A significant mid-cycle evolution occurred with the introduction of Electronic Fuel Injection (EFI) in 1999, offering improved throttle response alongside the standard carbureted versions. The ZR 500 models consistently featured Arctic Cat's AWS V front suspension and FasTrack Long-Travel Rear Suspension System. Trims primarily distinguished between carbureted and EFI versions, with some Limited Edition (LE) models also available. Q: How do I know which ZR 500 model I have?
A: To ensure compatibility with specific parts, please use the year and edition selector on this page. The ZR 500 saw variations, notably with the introduction of EFI, which can affect part fitment.
Maintenance
| Component | Interval | Details |
| Oil Filter (2-stroke engine) | Not applicable | 2-stroke engines like the ZR 500 do not have a traditional engine oil filter. Lubrication is provided by oil mixed with fuel or via an oil injection system. The oil reservoir should be filled with the recommended 50:1 injection oil. |
| Drive Belt | Inspection: Every 50 hours or if performance declines. Replacement: 2,400 to 4,800 km or if worn/damaged. | A new belt requires a break-in period of approximately 40 km at 3/4 throttle or less. Check the belt for cracks and tears. Remove belt dust buildup from clutch faces annually. |
| Spark Plug | Inspect and replace as needed | Inspect, replace, gap, or clean spark plugs. Gas/oil mixture can cause spark plug fouling and excessive carbon buildup. |
| Air Filter | Clean before storage | Clean the air filter as part of storage preparation. |
| Coolant | Check: Beginning and mid-season. Replacement: Every 2 years. | Maintain fluid levels. Check coolant levels at the beginning of winter and halfway through the season. |
| Drive Chain | Lubrication: Every 20 operating hours | Lubricate with a dry, graphite-based chain lubricant. Inspect for dirt accumulation before each lubrication. |
| Fuel Filter (Carbureted Models) | Inspect and replace as needed | Inspect the in-line fuel filter and replace if necessary. |
