Engine Displacement:
660cc (Specific variant may vary; manual will detail exact engine code)
Engine Manufacturer Source:
Likely Yamaha-based (e.g., Phazer engine family, based on common Arctic Cat practices of the era).
Horsepower Range Estimated:
Approx. 70-80 HP (Specific output depends on tuning and variant)
Fuel Delivery:
Fuel Injection (EFI) - Specific system details will be in the manual.
Cooling Method:
Liquid-cooled
Type:
CVT (Continuously Variable Transmission) with Arctic Cat's ACT Diamond Drive or similar clutch system.
Clutch Adjustment:
Detailed procedures for primary and secondary clutch inspection, service, and adjustment will be covered.
Drive Case Oil:
Specific API GL-4 or GL-5 gear oil meeting Arctic Cat's viscosity and specification requirements (e.g., SAE 75W/90, detailed in manual).
Braking System:
Hydraulic disc brake system (specifics on caliper, rotor, and fluid type in manual).
Lighting:
Headlights, taillights, brake lights, and instrumentation illumination (wiring and bulb specifications covered).
Initial Inspection:
First 10-hour or 100-mile service (includes chain case oil, clutch inspection, general lubrication).
Annual Maintenance:
Annual service typically includes spark plug replacement, air filter inspection/replacement, coolant check, track tension check, general lubrication.
Chain Case Oil Change:
Recommended every 100 hours or annually (refer to manual for exact mileage/hour interval).
Engine Oil Type:
Specific Arctic Cat synthetic 4-stroke snowmobile oil or equivalent meeting API SG/SH/SJ, JASO MA, or CCMC G-4 specifications. Viscosity typically SAE 0W-40 or 5W-40 (refer to manual for exact spec and capacity).
Coolant Type:
Ethylene glycol-based antifreeze (typically a 50/50 mix with distilled water) meeting ASTM D3306 standards. Specific color or Arctic Cat P/N may be specified.
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid (refer to manual for exact specification).
Clutch Wear:
Wear on clutch buttons, rollers, and spring fatigue can lead to performance degradation. Regular inspection and service are crucial.
Drive Belt Maintenance:
Proper belt tension and condition are vital for efficient power transfer and longevity. Belt breakage is a common roadside issue if not maintained.
Track Tension:
Improper track tension can lead to accelerated wear on the track, suspension components, and drive components.
Manufacturer:
Arctic Cat Inc. (A long-standing American manufacturer of snowmobiles, ATVs, and UTVs).
