🏷️ Basic Information Identification Make: Arctic Cat Model: Panther Year: 1974 Engine: Sachs KM24 Wankel Rotary Codes Manual Product Code: Likely an internal Arctic Cat or distributor code (not provided in product info) Vehicle Vin Format: Not applicable to snowmobiles in the modern sense; identification would be via chassis/engine serial numbers. 👋 Introduction Market Position Historical Context: The 1974 Arctic Cat Panther was a significant model in the burgeoning snowmobile market, known for its performance and reliability. This era saw fierce competition among manufacturers like Polaris, Ski-Doo, and Yamaha. Competitive Analysis Comparative Advantages: The Panther with the Sachs KM24 Wankel engine offered a unique proposition due to its rotary engine technology, aiming for smoother power delivery and potentially higher power-to-weight ratios compared to traditional piston engines of the era. Key Features Wankel Engine Advantage: The Wankel rotary engine's inherent simplicity (fewer moving parts), higher RPM capability, and smooth operation were key selling points. Chassis Design: Arctic Cat was known for robust chassis designs that could handle demanding snow conditions. Serviceability: A comprehensive service manual like this is crucial for maintaining such a specialized machine, especially with the unique Wankel powerplant. 📋 Manual Details Coverage Areas Systems Covered: Engine (Sachs KM24 Wankel), Fuel System, Ignition System, Lubrication System, Cooling System, Clutch System (Primary & Secondary), Drive Train, Track System, Suspension System (Front & Rear), Steering System, Braking System, Electrical System (Lighting, Ignition, Accessories), Chassis, Bodywork.

Performance Horsepower: Typically in the range of 20-30 HP (specific figures for the 1974 KM24 in the Panther may vary slightly). Torque: Not readily available in easily comparable figures to piston engines; Wankels tend to produce peak torque at higher RPMs. Fuel System Carburetion: Single or dual Mikuni or similar carburetor(s) - specific model would be detailed in the manual. Fuel Type: Unleaded gasoline (standard for the era) Lubrication System Type: Oil injection or pre-mix (manual will specify correct procedure and oil type). Cooling System Type: Air-cooled 🔧 Transmission Standard Type: CVT (Continuously Variable Transmission) - commonly referred to as a clutch drive system. Components: Primary Clutch (Drive), Secondary Clutch (Driven), Drive Belt. Optional Gearing: No multi-speed transmission; relies on CVT for gear ratio changes. Features Clutch Maintenance: Manual will detail inspection, cleaning, roller replacement, spring replacement, and belt wear. 📐 Dimensions Exterior Length: Varies by specific Panther sub-model, but typically around 70-80 inches. Width: Varies, typically 30-40 inches. Height: Varies, typically 30-40 inches. Weights Dry Weight: Approximately 300-350 lbs (dry weight, without fluids and rider). Cargo Storage: Typically a small storage compartment behind the seat or under the hood. Manual will detail access and capacity. 🛡️ Safety Features Ratings Historical Standards: Snowmobiles of this era were not subject to rigorous safety ratings like modern vehicles. Safety was primarily dependent on rider skill and mechanical condition. Active Features Braking System: Drum brake...
