Type:
Arctic Cat's own Continuously Variable Transmission (CVT) system, often referred to as 'Torque Sensing Drive' or similar.
Options:
N/A (CVT was standard for performance models of this era).
Features:
Automatic engagement and ratio adjustment for optimal power delivery and acceleration.
Drive Belt:
Specific part numbers and inspection guidelines for the drive belt would be in the manual.
Length:
Specific dimensions would be found in the manual, but typically around 100-110 inches.
Width:
Specific dimensions would be found in the manual, but typically around 30-35 inches.

Features:
N/A (No electronic driver assistance features).
Features:
N/A (No connectivity features).
Oil Change:
Annual or per manufacturer recommendation (usually 1000-2000 miles if applicable, but for 2-stroke, focus is on top-end inspection).
Spark Plugs:
Inspect every 500-1000 miles, replace as needed. Specific plug type and gap in manual.
Drive Belt:
Inspect before each ride for cracks, fraying, or wear. Replace when worn to specifications in the manual.
Clutch Maintenance:
Periodic inspection and cleaning of primary and secondary clutches; check for worn rollers, buttons, or springs.
Lubrication:
Regular lubrication of suspension pivots, steering components, and chaincase (if applicable) as per manual.
Engine Oil:
High-quality 2-stroke snowmobile oil. Ratio and type specified in manual (e.g., TC-W3 or equivalent).
Chaincase Oil:
Specific gear oil type (e.g., SAE 80W-90 GL-4 or GL-5) and capacity would be detailed in the manual.
Common Problems:
Carburetor jetting issues due to altitude or fuel quality; clutch wear; track tension adjustment; potential overheating if cooling system is not maintained; ignition system reliability.
Remedies:
Proper jetting and tuning; clutch service and belt replacement; track adjustment; ensure cooling fins are clean; check ignition components.
Heritage:
Arctic Cat, founded in 1960, has a long history of innovation in snowmobile manufacturing, known for performance and durability.
Panthera Line:
The Panthera line was a popular series for Arctic Cat, often featuring more premium amenities and higher performance engines compared to their basic models. The 'F/C' designation indicates a 'Full Cabin' design.
Manufacturing Location:
Likely Thief River Falls, Minnesota, USA (Arctic Cat's primary manufacturing location).
Production Years:
The Panthera 5000 F/C was produced in the mid-to-late 1970s. Specific production numbers are not readily available but it was a significant model for the brand.
