Harley 1948 Panhead OEM Steel Ribbed Outer Primary Cover Knucklehead UL FL For Sale

This configuration features three distinct vertical structural reinforcing ribs running down the midsection channels, which is correct for. [1, 2, 3]Finished in an older, heavily weathered dark charcoal gray enamel paint, this original survivor part has a massive vintage look. It features the large open rear clutch inspection hub circle and the smaller front motor sprocket inspection opening path.Condition Details & Project Note:

• Physical Structure: The heavy-gauge stamped steel hull is solid and straight across the main geometry. The outer perimeter sealing lips are unwarped, and all perimeter screw holes remain completely intact with no tears, cracked mounting eyelets, or previous structural weld repairs.
• Cosmetic Surface Finish: This component is in authentic vintage survivor condition. The paint is heavily chipped and scratched, showing deep real-world character. Localized flash oxidation, fine pitted scoring, and natural surface rust scale patterns are visible across the high-wear edges and structural recesses.
• Interior Casing Condition: The inner chamber is structurally sound but holds 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 base for complete media-blasting and a high-mirror re-chrome or gloss black paint overhaul.
