Description

Complete Loaded Primary Drivetrain Assembly — Lifestyle Powersports Performance Vault
Up for sale is a genuine, Harley-Davidson Factory OEM Big Twin 5-Speed Loaded Clutch Hub and Shell Assembly Kit (Built around master factory assembly number: #37707-90A / Replaces older index: #37707-90). Sourced from a clean warehouse layout, this entire used bundle comes completely assembled with all the vital internal drivetrain components you need to drop straight into your primary case.
Unlike empty bare baskets or stripped hubs that require buying separate plate packs, costly center bearings, and separate ring gears, this complete unit eliminates assembly guesswork and is ready for mockup or final install sequence.
Product Specifications & Mechanical Parameters:
  • Brand: Harley-Davidson (Original Equipment Manufacturer - OEM Performance Core)
  • Component Type: Transmission Clutch Shell Drum and Inner Hub with Full Internals Stack
  • Starter Ring Gear Sizing: 102-Tooth (102T Profile designed to mesh with 1989-1993 standard 9-tooth starter jackshaft pinion gears).
  • OEM Factory Master Assembly Reference: #37707-90A (replaces legacy index #37707-90)
  • Inner Hub Core Style: Modern 5-speed straight splined center bore (slides directly onto splined transmission mainshafts).
  • Platform Fitment Bounds: Direct factory drop-in replacement for standard 5-speed diaphragm clutch assemblies on 1990 to 1993 Harley-Davidson Big Twin Evolution models:
    • 1990–1993 Softail (Fat Boy FLSTF / Heritage FLSTC / Custom FXSTC / Springer)
    • 1990–1993 Touring (Electra Glide FLHT / Ultra Classic FLHTCU / Tour Glide)
    • 1991–1993 Dyna Glide (Super Glide FXD / Low Rider FXDL / Wide Glide FXDWG)
    • 1990–1993 FXR Series (Super Glide FXR / Low Rider FXRS / Sport Glide)
  • Exclusions: Will NOT fit early 1980–1989 5-speed setups (which use a totally separate starter engagement mechanism) or 1994–2006 models, which switched to a different pitch 102-tooth ring gear optimized for a 10-tooth starter pinion configuration.
  • Included Components in this Listing:
    • One (1) OEM 5-Speed Outer Clutch Shell Basket with pre-pressed center bearing
    • One (1) OEM 102T Starter Ring Gear and Duplex Primary Chain Driven Sprocket
    • Internal Splined Inner Clutch Hub Core
    • Complete matched internal stack of used Friction Clutches & Steel Drive Plates (would replace)
    • One (1) Mainshaft Clutch Hub Retention Locknut
  • Condition Details: Solid used builder stock. The teeth on the rear primary drive duplex sprocket and the 102T starter ring gear show sharp, even profile trajectories with zero flat spots or rolled metal lines. Internal spline channels matching the transmission shaft are square and crisp. The aluminum outer fingers and inner plate tracking splines show typical light, uniform wear consistent with normal operation and are free of deep gouging or notch ridges. Coated in a light preservation layer of storage oil to shield against warehouse humidity.
