Detailed Description

The FAG SR3496 is a transmission pump repair sleeve engineered to create a new sealing surface over worn or scored shafts. Its stainless steel, heat-treated construction supports long-term service in demanding drivetrain environments, while the precise dimensions help ensure a proper fit on 1.750 inch shafts. This makes SR3496 a direct repair option for vehicles such as Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications where shaft wear can affect sealing performance.

Because the sleeve installs without shaft removal or machining, it can reduce repair time and avoid the cost of replacing otherwise serviceable components. The FAG SR3496 is also listed across many front, rear, and N/A-position applications, including older GM truck, SUV, and passenger car platforms.

What It Helps Fix

• Transmission pump shaft seal leakage caused by wear or scoring
• Premature shaft wear at the sealing surface
• Reduced sealing performance after repeated use
• Costly shaft replacement when the base shaft is still serviceable
• Repair delays caused by machining requirements

Installation Notes and Tips

Confirm shaft diameter before installation; this sleeve is specified for a 1.750 inch shaft. Clean the shaft surface thoroughly and inspect for damage that could affect sleeve seating or seal contact. The listed installation depth is 0.813 inch, so verify available space before fitting the sleeve. For fitment verification, match your vehicle year, make, model, and position exactly; examples include Fits 1999-2010 Chevrolet Silverado 1500, front and Fits 1999-2013 GMC Sierra 1500, N/A.
