Product Details

The FAG SR3571 is a crankshaft repair sleeve used to create a renewed sealing surface where wear has affected the original shaft finish. Its 3.875-inch shaft diameter, 4.219-inch flange diameter, 1-inch width, and 1.875-inch installation depth are engineered for a precise fit on the intended crankshaft repair application. For Ford diesel service, this sleeve is listed for 1983-1994 Ford F-250 rear, 1983-1994 Ford F-350 rear, and 1988-1992 Ford E-350 Econoline rear applications, with additional year-specific notes for certain F-250 and F-350 configurations. The FAG SR3571 is a practical repair solution when the crankshaft sealing area is worn but the shaft itself remains serviceable.

What It Helps Fix

• Oil leakage at a worn crankshaft sealing surface
• Premature seal wear caused by shaft groove damage
• Repair needs where crankshaft removal is not practical
• Surface wear on Ford F-250 and Ford F-350 rear applications
• Sealing issues on E-350 Econoline rear diesel service

Installation Notes and Tips

Confirm shaft diameter and installation depth before installation to ensure the sleeve matches the repair area. Clean the shaft thoroughly and inspect the sealing surface for scoring, grooves, or corrosion before fitting the sleeve. This part is used on specific Ford F-250, Ford F-350, and Ford E-350 Econoline rear applications, so verify year, position, and notes against the vehicle listing before service. FAG SR3571 is also referenced by SKF 99387 and 4133571100 for the same application.
