Type:
Automatic CVТ (Continuously Variable Transmission)
Gear Selection:
High (H), Low (L), Neutral (N), Reverse (R), Park (P).
Engine Braking:
Effective engine braking provided by the CVT in lower gears.
Drive System:
Shaft drive to rear differential; shaft drive to front differential with on-demand 4WD engagement.
Cvt Fluid Type:
Arctic Cat recommends their proprietary CVT fluid or a compatible synthetic CVT fluid. Check manual for specific part numbers or specifications.
Oil Change Interval:
Every 100 hours or 1,000 miles (1,600 km), or annually, whichever comes first (refer to manual for precise intervals).
Air Filter Inspection:
Inspect every 25 hours, clean/replace as needed. More frequent inspection in dusty conditions.
Spark Plug Replacement:
Typically every 100 hours or annually.
Cv Belt Inspection:
Inspect regularly for wear and damage, replace as needed.
Brake Fluid Type:
DOT 4 Hydraulic Brake Fluid.
Coolant Type:
Ethylene Glycol based antifreeze (50/50 mix with distilled water). Typically green or orange coolant compatible with aluminum engines.
Gear Oil Front Differential:
