National Federal-Mogul 99499 Redi-Sleeve Shaft Repair Sleeve

National (Federal-Mogul) 99499 Redi-Sleeve — a thin-wall stainless steel repair sleeve that restores a worn shaft sealing surface to like-new so a standard oil seal can be reused without replacing or machining the shaft. Fits a nominal 5.000" shaft OD (approx. 4.987"–5.000" worn range). Made in USA. **Application:** Universal shaft repair for worn crankshaft, camshaft, transmission, or accessory shaft seal surfaces in the ~5.000" range — widely used on heavy-duty diesel and marine engines. **Condition:** New old stock in original Federal-Mogul packaging; box shows shelf wear. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
