Troubleshooting Guides:
Systematic diagnostic procedures to identify and resolve common problems and malfunctions.
Engine Rebuild Procedures:
Detailed steps for complete engine disassembly, inspection of critical wear surfaces (crankshaft journals, connecting rod bearings, cylinder bores, piston rings), and reassembly with appropriate torque specifications and clearances.
Electrical Troubleshooting:
Wiring diagrams specific to the 1971 models, with guidance on diagnosing faults in starting, charging, lighting, and ignition circuits using test equipment like multimeters.
Depth Of Coverage:
Comprehensive, suitable for both routine maintenance and in-depth engine and transmission rebuilds. Covers mechanical and electrical aspects.
Diagnostic Techniques:
Includes methods for diagnosing engine performance issues, transmission engagement problems, and electrical faults through systematic testing and observation, often aided by specific charts.
Special Tools:
Likely lists specific Harley-Davidson special tools required for certain procedures, such as bearing pullers, timing gauges, and seal drivers.
Engine Type:
Air-cooled, OHV, V-twin
Engine Displacement:
74 cubic inches (1208cc)
Engine Designation:
Known as the 'Shovelhead' engine, though 1971 marked a transition year and still shared some characteristics with the earlier Panhead, particularly in terms of case design and some internal components. The manual would cover specifics for the 1971 configuration.
Bore X Stroke:
3.4375 in x 4.25 in (87.3 mm x 108 mm)
Horsepower:
Approximately 55-60 hp (estimate, as official figures were not always precisely published).
Torque:
Significant low-end torque, typical of Harley-Davidson V-twins of this era. Specific figures vary but are crucial for understanding the engine's character.
Carburetor:
Likely a Linkert M74 or potentially an early Keihin butterfly carburetor.
Fuel Type:
Leaded gasoline, Octane rating dependent on era-specific recommendations (likely premium leaded).
Fuel Delivery:
Gravity feed from fuel tank to carburetor.
Oil System:
Total loss oil system with a separate oil tank. Oil is mixed with fuel or injected and not recirculated to the crankcase like modern systems.
Oil Change Interval:
Typically every 1,000 to 2,000 miles, or as specified in the manual, due to the total-loss oil system. Specific recommendations vary by oil type and usage.
Engine Tune Up Interval:
Regular checks of ignition timing, carburetor settings, and spark plugs every few thousand miles or as needed for optimal performance.
Engine Oil Type:
The manual will specify the correct grade and type of oil, likely a straight-weight or multi-viscosity oil suitable for air-cooled V-twins (e.g., SAE 50 or 20W-50 depending on ambient temperature). Harley-Davidson recommended specific oils of the era.
Primary Chaincase Oil:
Manual will specify primary chaincase oil and its capacity. This system is separate from the engine crankcase and transmission.
Brake Fluid Type:
Drum brakes of this era typically did not use hydraulic fluid; mechanical actuation was standard. If any hydraulic components were present, the manual would specify the correct DOT fluid.
Known Issues Common:
Oil leaks (from seals and gaskets), ignition system reliability (points and condensers), carburetor tuning issues, valve adjustments requiring precision, and potential wear in the transmission and primary drive components.
Shifter Lever Wear:
Wear in the shifter linkage and drum can lead to difficult gear changes.
Carburetor Fouling:
Linkert carburetors can be prone to fouling and require careful cleaning and adjustment.
Valve Stem Seals:
Early Shovelheads could experience wear in valve stem seals, leading to oil consumption and blue smoke on deceleration.
Brand Heritage:
Harley-Davidson, established in 1903, has a long-standing reputation for building American V-twin motorcycles known for their distinctive sound, power, and durability.
Model Evolution:
The Electra Glide, introduced in 1965, was Harley-Davidson's first fully-faired touring motorcycle. The Super Glide, introduced in 1971, offered a more stripped-down custom look with a 'boat tail' rear fender. Both models utilized the evolving Shovelhead engine and shared many chassis components.
Production Years Relevant:
1971 was a pivotal year, marking the introduction of the Super Glide and the continued development of the Shovelhead engine which would power Harley-Davidsons for many years.
