Engine Type:
Information on specific engine configurations (e.g., inline-4, V6, etc.) for the 1972 Polaris Custom II 2 is not explicitly detailed in the provided product description. However, a comprehensive service manual would contain these specifics, including engine codes, bore, stroke, compression ratios, and valve timing.
Engine Disassembly And Assembly:
The manual provides detailed, illustrated instructions for the complete disassembly, inspection, reconditioning, and reassembly of the engine, including torque specifications for all fasteners.
Horsepower And Torque:
Specific horsepower and torque figures are not provided in the product summary. The manual would contain detailed specifications for engine output, power curves, and recommended operating parameters for various engine options offered in 1972.
Carburetion And Fuel Delivery:
The manual would cover details on the carburetor(s) (make, model, jetting, adjustment procedures), fuel pump, fuel filter, and fuel tank specifications. Specific carburetor models such as Rochester, Holley, or Carter are likely to be covered with detailed diagrams and rebuild instructions.
Transmission Type:
The product description does not specify the transmission type (e.g., manual or automatic) or gear ratios. A complete service manual for this era would detail the applicable transmission(s), including internal components, clutch operation (for manual), torque converter (for automatic), and shift linkage adjustments.
Optional Transmission Details:
If multiple transmission options were available for the 1972 Polaris Custom II 2, the manual would cover them distinctly, providing specific procedures and specifications for each.
Transmission Features:
The manual would detail features such as gear ratios, clutch assembly specifications, automatic transmission hydraulic controls, and any specific maintenance requirements for the transmission fluid and filter.
Body Style And Dimensions:
The product description does not provide exterior dimensions (length, width, height). This information, along with curb weight and wheelbase, would be present in the manual's specifications section.
Interior Dimensions:
Interior space and seating configurations are not detailed. The manual may include some interior component removal and installation procedures but rarely explicit interior dimension data.
Cargo Capacity:
Cargo volume or capacity is not specified. For vehicles of this era, cargo areas were typically trunks or integrated cargo spaces whose volume was not as commonly published as it is today.
Curb Weight:
Curb weight, gross vehicle weight rating (GVWR), and axle weight ratings would be specified in the manual's general specifications section, crucial for load-carrying and towing considerations.
Crash Test Ratings:
Official NHTSA or IIHS crash test ratings were not standardized or widely published for vehicles in 1972. The manual would focus on mechanical safety systems rather than crashworthiness ratings.
Active Safety Systems:
Active safety features would primarily include the braking system (e.g., hydraulic system integrity, brake fluid specifications) and steering system.
Passive Safety Features:
Passive safety features for 1972 would typically include seat belts (if factory-equipped), interior padding, and potentially safety glass. The manual might detail seat belt anchor points and their maintenance.
Infotainment Systems:
For a 1972 model, technology would be rudimentary. The manual would cover the radio system (AM, perhaps FM), speaker wiring, and antenna installation/repair. No advanced infotainment features would be present.
Driver Assistance Features:
Driver assistance features were virtually non-existent in 1972 vehicles. Safety would be limited to mechanical systems like brakes and steering, and passive features like seatbelts.
Connectivity Features:
No modern connectivity features (Bluetooth, USB, Wi-Fi) would be present. The only 'connectivity' would be the vehicle's electrical wiring systems.
Scheduled Maintenance:
The manual provides detailed recommended service intervals for all major components, including oil changes, filter replacements (oil, air, fuel), spark plug replacements, ignition timing checks, brake inspections, fluid flushes (coolant, brake fluid), and lubrication services. These intervals are critical for longevity and performance.
Engine Oil Specifications:
The manual will specify the correct SAE viscosity grade (e.g., SAE 10W-30, SAE 20W-50) and API service classification for engine oil, crucial for proper lubrication and protection under varying operating conditions and ambient temperatures.
Coolant And Brake Fluid:
Specific types and capacities for engine coolant (e.g., ethylene glycol based, mixture ratio) and brake fluid (e.g., DOT 3, DOT 4) will be detailed, along with recommended change intervals.
Transmission And Differential Fluids:
Correct fluid types and capacities for the transmission (automatic or manual), power steering (if equipped), and rear differential will be clearly listed, along with service requirements.
Chassis Lubrication Points:
A detailed lubrication chart indicating all grease points, such as ball joints, tie rod ends, U-joints, and other chassis components, along with recommended lubricant types and service intervals.
Common Wear And Tear:
While not explicitly listing 'known issues' as a defect list, the manual's troubleshooting section implicitly addresses common wear and tear items by providing diagnostic procedures for symptoms typically arising from component fatigue or malfunction, such as carburetor wear, ignition component aging, and suspension wear.
Polaris Automotive Heritage:
Polaris is historically known for its recreational vehicles (snowmobiles, ATVs, motorcycles). Their foray into the automotive market, particularly with models like the Custom II 2, represents a significant, though perhaps less documented, chapter of their history. This manual is a direct link to that specific automotive period for Polaris.
Polarismotor Historical Context:
Understanding Polaris's background in engine and vehicle manufacturing provides context for the engineering and design principles likely applied to the Custom II 2.
Custom Ii 2 Evolution:
Information on specific model evolution leading up to the 1972 Custom II 2 is not provided. However, a service manual would detail the specific changes and updates for the 1972 model year compared to previous iterations, if any.
Manufacturing Details:
Production numbers, manufacturing plant locations, and specific trim level variations for the 1972 Polaris Custom II 2 are not in the product summary. The manual, however, is the definitive source for understanding the factory's intended production and assembly methods.
