Paper Type:
Not applicable for digital format, but original manuals would use durable paper suitable for workshop environments.
Engine Family:
Harley-Davidson Shovelhead V-Twin
Displacement:
Commonly 74 cubic inches (1200cc) OHV V-twin.
Bore Stroke:
Typically 3.4375 in. x 4.00 in. (87.3 mm x 101.6 mm).
Compression Ratio:
Varied by specific model and year, often around 8.0:1 or higher.
Horsepower:
Estimated 50-60 hp at ~5000 RPM (varies).
Torque:
Estimated 65-75 ft-lbs at ~3500 RPM (varies).
Carburetor:
Typically a Keihin butterfly or Linkert carburetor, or a S&S Super E/G depending on factory or aftermarket fitment. Manual will detail specific types.
Fuel Type:
Unleaded gasoline, typically with an octane rating of 91 or higher recommended for optimal performance and longevity.
Ignition System:
Contact point ignition system with breaker points and condenser, likely dual coils for the V-twin configuration.
Type:
4-speed constant mesh, foot-shift, hand-clutch operation (left hand).
Configurations:
Primarily 4-speed. Some models might have variations in gear ratios.
Clutch Type:
Wet multi-plate clutch, operated by hand lever.
Gear Ratios:
Specific ratios will be detailed in the manual for each gear, crucial for performance tuning and diagnostics.
Transmission Oil:
Typically Harley-Davidson's recommended primary/transmission lubricant or an equivalent V-twin specific gear oil (e.g., SAE 75W-90 or 85W-140, check manual for specific viscosity).
Crash Testing:
No formal crash testing ratings exist for motorcycles from this era in the way they do for modern cars. Safety primarily relies on rider skill and robust mechanical design.
Braking System:
Drum brakes front and rear. Maintenance of brake pads, drums, and fluid is critical for stopping power.
Lighting:
Headlight, taillight, brake light, turn signals (if equipped), and running lights. Electrical system integrity is key.
Oil Change:
Typically every 2,000-3,000 miles or annually, whichever comes first. Engine oil and transmission oil often share the same sump on these models, requiring careful monitoring of levels and condition.
Ignition Points Condenser:
Require periodic inspection and adjustment (e.g., every 2,000-3,000 miles) for optimal performance. Replacement as needed.
Carburetor Cleaning:
Recommended annually or as needed, especially if performance issues arise.
Engine Oil Capacity:
Approximately 4 quarts (3.8 liters) for the combined engine/transmission/primary chaincase, but always verify with the manual for the specific model year.
Engine Oil Viscosity:
Commonly 20W-50 motorcycle-specific oil, though the manual will specify the exact recommended viscosity based on operating temperature.
Primary Chaincase Oil:
If separated or for initial fill, refer to manual. Often shared with engine oil. Specific primary chaincase lubricant might be recommended.
Carburetor Leaks:
Venting and sealing of older carburetors can be prone to leaks if not properly maintained.
Oil Leaks:
Older Harley-Davidsons are known for minor oil seepage from gaskets and seals. The manual provides guidance on gasket replacement and torque specifications.
Ignition System:
Contact points and condensers can wear and require adjustment or replacement for consistent running.
Charging System:
Generator or early alternator systems can require attention for consistent battery charging. The manual covers testing and repair.
Legacy:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer known for its powerful V-twin engines and distinctive styling. The Electra-Glide series represents a cornerstone of their touring and cruiser offerings.
Electra Glide Lineage:
The Electra-Glide was introduced in 1965, marking the transition to the Shovelhead engine in 1966. This 1970-1972 period represents early Shovelhead models, known for their raw power and distinct American character.
Manufacturing Era:
Produced by Harley-Davidson in the United States during a period of significant change and evolution for the company.
