Description

Vintage Factory Primary Drive Stock — Lifestyle Powersports Inventory Vault
Up for sale is a genuine, Harley-Davidson Factory OEM 45" Flathead 23-Tooth Engine Primary Drive Motor Sprocket. Sourced from an early warehouse collection, this steel component remains in solid, used vintage condition. Unlike modern cheap, soft reproduction drivetrain components, this authentic factory-forged casting features high-grade, heat-treated steel to prevent tooth deflection or premature spline wear under heavy torque loads.
Product Specifications & Mechanical Parameters:
  • Brand: Harley-Davidson (Original Equipment Manufacturer - OEM)
  • Component Type: Engine Crankshaft Primary Drive Motor Sprocket
  • Sprocket Tooth Count: 23-Tooth (23T Style for Single-Row Primary Chains)
  • Bore Type: Tapered center shaft configuration with built-in woodruff keyway slot
  • Platform Fitment Bounds: Direct factory replacement for standard primary setups on 1929 to 1952 Harley-Davidson 45" Big Twin Flathead lines:
    • 1929–1952 Harley WL / WLA / WLC / WLD / WR Solo Models
    • 1929–1973 Harley G / GA Servi-Car Utility Platforms
  • Condition Details: Authentic used vintage stock with light surface flash rust/patina common to long-term dry garage storage. The 23 teeth show solid profile lines with plenty of material life left and zero sharp hooks or valley thinning. The critical internal tapered bore and keyway channel are sharp and free of spin marring or wallowing.
