Cooling System:
Air-cooled
Horsepower:
Estimated 5-10 HP, optimized for low-end torque and steady operation.
Torque:
Not explicitly stated in typical golf cart specs, but designed for consistent torque delivery for acceleration and hill climbing.
Carburetor Type:
Single barrel carburetor, specific make and model vary (e.g., Tillotson, Keihin). Manual provides detailed tuning and rebuilding instructions.
Fuel Type:
Unleaded gasoline
Fuel Capacity:
Typically 2-4 gallons, depending on the specific model variant.
Transmission Type:
Automatic (likely a centrifugal clutch and belt drive system for variable speed, common in golf carts of this era).
Optional Transmissions:
None specified for this era of golf carts.
Drive System:
Rear-wheel drive, via a chain or belt drive system from the engine/transmission assembly.

Approximately 40-50 inches (to steering wheel/seat level)
Curb Weight:
Approximately 300-450 lbs
Payload Capacity:
Typically rated for 2-4 passengers plus light cargo, estimated 400-600 lbs.
Safety Certifications:
No formal crash ratings typical for modern vehicles; safety focused on stability and operational limits for controlled environments.
Braking System:
Mechanical drum brakes on rear axle, possibly front brakes on later models or specific variants. Parking brake mechanism.
Steering System:
Manual steering, typically a direct linkage system. Neutral caster and camber angles.
Seatbelts:
Optional or not standard on early models.
Body Structure:
Steel frame chassis with molded plastic or metal body panels.
Engine Oil Change:
Every 25-50 operating hours or annually. Specific oil type and viscosity critical (consult manual).
Air Filter Cleaning Replacement:
Check every 25 operating hours, clean/replace as needed. Specific filter part number required.
Spark Plug Replacement:
Annually or every 100 operating hours. Specific spark plug type and gap critical (e.g., Champion, NGK).
Fuel Filter Replacement:
Annually or as needed if fuel delivery issues arise. Specific filter element required.
Brake Adjustment:
Check and adjust annually or if braking performance degrades.
Engine Oil Type:
SAE 30 or 10W-30 HD rated oil (refer to manual for specific viscosity and API service classification).
Gearbox Oil:
Specific gear oil or grease for the transaxle/drive unit. Manual will specify type and quantity.
Grease Type:
General purpose lithium-based grease for chassis lubrication points.
Common Wear Items:
Carburetor gumming, worn clutch assemblies, brake shoe wear, electrical connection corrosion, starter drive wear.
Engine Performance Degradation:
Can occur due to carbon buildup in combustion chamber, worn piston rings, or ignition timing issues. Manual addresses diagnosis.
Suspension And Steering Play:
Ball joints, tie rod ends, and wheel bearings can develop wear over time, leading to steering looseness. Manual guides replacement.
Harley Davidson Legacy:
Harley-Davidson, a legendary American motorcycle manufacturer founded in 1903, known for its V-twin engines and iconic designs. Their move into golf carts represented an expansion of their industrial and utility vehicle interests.
