It is an essential mechanical asset for anyone overhauling an early Knucklehead, Panhead, or Shovelhead chopper, building a vintage bobber project, or restoring a classic ratchet-top/rotary-top gearbox assembly [INDEX].
🏍️ Fitment & Vehicle Compatibility:
Direct factory drop-in application for standard right-side 4-speed manual gearboxes across the classic Big Twin generations [INDEX]:
Harley-Davidson Knucklehead / Panhead / Shovelhead: Fits 1936 to 1984 EL, FL, FLH Electra Glide platforms, and 1971 to 1985 FX, FXE Super Glide, FXS Low Rider, and FXWG Wide Glide configurations [INDEX].
🔍 Condition Notes:

Shifting Dogs: The 4 outer face-locking engagement dogs and internal slider teeth are structurally solid, true, and free of severe rounded profiles, edge gouges, or deep back-cut wear from missed shifts [INDEX].
Internal Splines: The internal tracking spline teeth are clean, sharp, and entirely free from step-wear wallowing or twist deformation [INDEX].
Cosmetics: The slider shows uniform mechanical polishing wear, typical cosmetic transmission oil staining, and minor superficial storage oxidation from sitting in an inventory bin (as clearly detailed in the product photos), but it is fully intact and ready to clean, lube, and drop into your shifting stack.
Original Equipment Manufacturer (OEM) Harley-Davidson Shovelhead Big Twin 4-Speed Transmission Replacement Gears & Shifting Fork Set.
Application: 4-Speed Manual Transmission Mainshaft / Countershaft Internal Gearbox Internals
Components Included: (4) Face-Engagement Slide Gears, (1) Dual-Diameter Splined Gear Cluster Hub, (1) Cast Steel Shifting Fork Guide Link
Up for sale is a genuine factory Harley-Davidson 4-speed transmission internal gear repair bundle. Removed directly from a classic Big Twin Shovelhead gearbox, this is an authentic US-made heavy-duty steel component grouping. This kit includes four slider engagement gears, the dual-tiered splined main gear hub, and one matching factory shifting fork.
Avoid cheap unbranded reproduction transmission gears that suffer from soft steel heat-treating, which leads to rapid tooth shearing or rounded engagement corners under high engine torque. These factory original components are forged from high-tensile steel alloy and built to survive hard acceleration and decades of heavy road use. This grouping is the perfect mechanical solution for replacing stripped teeth, fixing a bike that pops out of 2nd or 3rd gear, or rebuilding a custom vintage ratchet-top or rotary-top chopper transmission.
🏍️ Fitment & Vehicle Compatibility:
Direct drop-in mechanical replacement for standard 4-speed manual gearboxes across the classic Shovelhead era:
Harley-Davidson Shovelhead Big Twins (1200cc / 74ci & 1340cc / 80ci): Fits 1966 to Early 1984 FL, FLH, FLHS, FX, FXE, FXEF, FXS Low Rider, and FXWG Wide Glide configurations utilizing standard 4-speed main and countershaft layouts.
🔍 Condition Notes:
This is a pre-owned vintage factory engine/transmission takeoff component grouping.
The Gear Teeth: All individual gear teeth profiles are structurally sound, sharp, and true, entirely free from broken steps, heavy face pitting, or chipped edges.
Engagement Dogs: The face-engagement locking dogs and matching recessed pockets are clean with crisp, square tracking corners (not heavily rounded out or wallowed from missed shifts).
Shifting Fork: The cast steel shifter fork is perfectly straight, true, and free of crash twists or hairline stress cracks. The tracking pads show normal polished friction marks from normal use but retain plenty of material thickness.
Splines: Internal hub splines are deep and clear. Components display typical superficial oil coloration and light cosmetic storage oxidation (as clearly detailed in the images), but they are fully ready to clean, oil, and assemble into a working gearbox.
Original Equipment Manufacturer (OEM) Harley-Davidson Twin Cam 5-Speed Side Transmission Bearing Housing Block Case Assembly.
Internal Trapdoor Casting Number: 35036-99
Finish: Factory Original Black Wrinkle-Finish Coating
Configuration: Complete side-block assembly with pressed trapdoor, mainshaft ball bearing, and countershaft ball bearing fully intact.
Up for sale is a genuine factory Harley-Davidson 5-speed transmission side bearing housing block cluster assembly takeoff. Removed directly from a smooth-shifting Twin Cam Big Twin engine drivetrain, this is an authentic US-made structural component grouping. It features the factory-original black wrinkle-finish outer coating and a precision diamond-pattern machined gasket interface tracking line.
Avoid the extensive garage labor of purchasing bare transmission housings, separate trapdoors, and loose bearings that require hydraulic shop presses and precision depth alignment tools to fit together safely. This pre-assembled component block drops straight onto your 5-speed transmission gearcase alignment dowels, cutting hours out of your rebuild time. It is the ultimate plug-and-play mechanical solution for repairing a stripped clutch cover port, fixing an oil leak at the trapdoor gasket plane, or replacing a cracked side casing block.
🏍️ Fitment & Vehicle Compatibility:
Direct factory drop-in application for standard 5-speed gearboxes across the rigid-mount Twin Cam 88ci and 95ci engine generations:

The Housing & Trapdoor: The structural cast aluminum block and inner trapdoor are completely solid with absolutely zero hairline stress cracks, impact fractures, or chipped corners along the mounting ears. Machined gasket surfaces are true and smooth.
The Bearings: Both internal heavy-duty steel ball bearings remain firmly pressed into their respective bores. They spin cleanly and smooth by hand with zero chattering, grinding, or out-of-spec lateral play.
Cosmetics: The factory black wrinkle-finish displays normal light cosmetic road scuffs and typical cleaning wear, but it presents very well and is free of major flaking or corrosion.
Please Note: This listing is for the side bearing housing block assembly exactly as pictured. Outer clutch release covers, gaskets, and mounting bolts are not included.
