Description

This is a genuine factory original OEM Harley-Davidson stamped steel "tin" outer primary cover. This classic vintage component features the traditional early rigid-frame styling, characterized by the large open rear clutch inspection hub circle profile and the structural diamond-stamping layout centered across the main body channel.

This specific unit comes exceptionally complete, featuring the factory center circular inspection window access port plate pre-secured to the diamond relief by its two original slot-head mounting screws.

Condition Details & Discrepancies (Please Read):

Physical Structure (Sealing Lip Dents): The inner perimeter steel sealing lip shows clear physical impact distortions, localized dents, and waviness along the bottom border tracking path. This lip edge will need to be dollied and flattened true by the buyer prior to final gasket sealing and mock-up alignment. All outer screw mounting holes remain fully intact without structural cracks or tears.
Cosmetic Surface Finish: This component is in authentic vintage survivor condition. The old chrome plating exhibits heavy character marks throughout, including widespread surface pitting, light scoring, age hazing, and visible chrome flaking along the upper crest edge. There is exposed metal showing natural flash surface rust scale detailing, giving it an excellent period-correct patina.
Interior Casing Condition: The raw inner chamber is structurally sound, retaining a dark layer of old primary oil film residues, grease deposits, and flash surface rust scaling. It is highly suitable for an un-restored survivor bobber or chopper build, or it serves as an excellent solid core candidate for professional media-blasting and a high-mirror re-chrome overhaul.

Please note that this listing includes exactly 1 used factory outer primary tin cover with its center port plate as pictured. Derby plates and mounting fasteners are not included.

3. COMPATIBILITY / FITMENT

Designed as a direct stock replacement or period-correct custom chopper application for 4-speed Big Twin models running rigid or early swingarm frame layouts without electric starters (replaces factory OEM reference 60505-36):

1936–1947 Harley-Davidson Knucklehead (E / EL / F / FL)
1948–1954 Harley-Davidson Panhead / Hydra Glide (FL / FLH)
1937–1948 Harley-Davidson Big Twin Flathead (U / UL / UH / ULH)

Please note: This traditional tin primary cover is engineered for early 4-speed chain-drive models running standard matching legacy steel inner covers. It will not line up with modern aluminum 5-speed drivetrains or later electric-start inner configurations.
