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.

Vehicle Information
Ski-Doo Mach Z 780 Snowmobile (1993-1996)
The Ski-Doo Mach Z 780, produced from 1993 to 1996, was a high-performance snowmobile known for its powerful triple-cylinder engine and innovative chassis. It was powered by a 774cc (often referred to as 780 type) liquid-cooled, 3-cylinder Rotax engine with R.A.V.E. valves, producing approximately 150 horsepower. Fuel delivery was managed by three Mikuni TM-38 carburetors and it featured three tuned exhaust pipes. The introduction of the Mach Z in 1993 marked significant innovations for Ski-Doo, including the first all-aluminum F-2000 chassis, which contributed to a significant weight reduction, and the first 2-stroke, 3-cylinder liquid-cooled engine in a production snowmobile. The 1993 model notably featured a fiberglass hood, which was replaced with plastic in subsequent years, and the introduction of Ultra Glide composite skis. The F-2000 chassis and 774cc engine remained consistent through 1996, with the DSA (Direct Shock Action) front suspension as a key feature. In 1996, a Mach Z LT (Long Track) variant was added to the standard lineup. FAQ:

Maintenance
| Component | Interval | Details |
| Oil Filter | Before every ride | 2-stroke engines do not have a traditional engine oil filter. Check the oil injection reservoir level and top off as needed. |
| Drive Belt | Before every ride (inspection); 50 hours (formal inspection) | Inspect the belt for signs of wear (cracking, fraying). Replace if wear signs are present or if performance is inconsistent. Typical lifespan: 2,500 to 5,000 km. It is recommended to start each season with a fresh belt. |
| Spark Plugs | Annually or more frequently | Replace annually for moderate use, or more frequently for aggressive riding (some suggest every 3-4 trips). Install new, properly gapped spark plugs after preseason preparation. |
| Air Filter | 25 to 50 hours or after each ride in harsh conditions | Check, clean, or replace regularly. Essential for optimal performance. In deep powder snow, periodically shake snow out of the filter and dry it. |
| Coolant | Every 2 years | Check level before every ride (cold engine). Some recommend annual or 4-5 year changes, but 2 years is a common guideline. |
These intervals are general guidelines. It is crucial to consult your specific model's owner's manual for precise recommendations.
