This Service Manual contains service and maintenance information for 2020 Arctic Cat ZR 9000 Thundercat snowmobile models. The manual is designed to aid service personnel in service-oriented applications. This manual is divided into sections that cover specific snowmobile components or systems and, in addition to the standard service procedures, include assembling, disassembling, and inspecting instructions. When using this manual as a guide, the technician should use discretion as to how much disassembly is needed to correct any given condition. The service technician should become familiar with the operation and construction of the components or systems by carefully studying the complete manual. This will assist the service technician in becoming more aware of and efficient with servicing procedures. Such efficiency not only helps build consumer confidence but also saves time and labor. All Arctic Cat publications and snowmobile decals display the words Warning, Caution, and Note to emphasize important information. The symbol ! WARNING identifies personal safety-related information. Be sure to follow the directive because it deals with the possibility of severe personal injury or even death. A CAUTION identifies unsafe practices which may result in snowmobile-related damage. Follow the directive because it deals with the possibility of damaging part or parts of the snowmobile. The symbol NOTE: identifies supplementary information worthy of particular attention. At the time of publication, all information, photographs, and illustrations were technically correct. Some photographs and illustrations used in this manual are used for clarity purposes only and are not designed to depict actual conditions.

Snowmobile Identification The Arctic Cat Snowmobile has two important identification numbers. The Vehicle Identification Number (VIN) is stamped into the tunnel near the right-side footrest or on top of the tunnel. The decal also displays pertinent production information. The Engine Serial Number (ESN) is stamped into the crankcase of the engine. These numbers are required to complete warranty claims properly. No warranty will be allowed by Arctic Cat if the engine serial number or VIN is removed or mutilated in any way.
Recommended Gasoline and Oil CAUTION Do not use white gas or gasoline containing methanol. Only Arctic Cat-approved gasoline additives should be used.
RECOMMENDED GASOLINE
The recommended gasoline to use in these snowmobiles is 87 octane regular unleaded. In many areas, oxygenates are added to the gasoline. Oxygenated gasolines containing up to 10% ethanol are acceptable gasolines. When using ethanol-blended gasoline, adding a gasoline antifreeze is not necessary since ethanol will prevent the accumulation of moisture in the fuel system. RECOMMENDED OIL
CAUTION Any oil used in place of the recommended oil may cause serious damage.
The recommended oil to use is Synthetic C-TEC4 Oil (p/n 6639-529 — gal.). After the engine break-in period, the engine oil and filter should be changed every 2500 miles or before prolonged storage.
Engine Break-In The engine (when new or rebuilt) requires a short break-in period before the engine is subjected to heavy load conditions. This engine does not require any pre-mixed fuel during the break-in period. There is never a more important period in the life of the engine than the first 500 km (300 miles). Since the engine is brand new, do not put an excessive load on it for the first 500 km (300 miles). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full throttle operation or any condition that might result in engine overheating must be avoided.
