Detailed Description

National 2655 is engineered as an oil seal for transmission output shaft sealing applications where dimensional accuracy matters. The seal measures 1.375 inches inside diameter, 2.254 inches outside diameter, and 0.405 inches thick, with a flanged outside diameter of 2.484 inches. Its polyacrylate construction and spiral lip profile are specified to support sealing at the shaft interface, while the Redicoat finish adds a protective coating to the sealing surface. National has supplied sealing products for more than 75 years, and this part reflects that focus on precision transmission sealing. This part cross-references ATP FO-213 and Bosch 13685 for the same application. National 2655 is listed across a wide range of Ford Ranger, Ford Explorer, Mazda B2300, Mazda B3000, and Mazda B4000 applications, along with additional Ford, Mazda, Mercury, and Lincoln transmission listings shown in the fitment data.

What This Seal Helps Address

• Transmission fluid seepage at the output shaft
• Oil leakage around the seal housing bore
• Wear-related sealing loss at the shaft interface
• Service replacement for aged or hardened transmission seals
• Leak repair on Ford Ranger, Ford Explorer, and Mazda truck applications

Installation Notes and Tips

This seal is listed for multiple Ford 4R44E, 4R55E, 5R44E, 5R55E, A4LD, C3, and Mazda M5M-D applications, so matching the transmission code is essential. Inspect the shaft surface and seal bore for scoring, corrosion, or debris before installing National 2655. Use clean transmission fluid on the sealing lip during assembly and confirm the seal seats evenly in the housing.
