Detailed Description

National 224066 is an oil seal for the manual transmission output shaft, engineered around precise metric dimensions for a proper housing and shaft interface. The seal measures 1.575 in. inside diameter, 2.610 in. outside diameter, and 0.315 in. width, with an overall width of 0.453 in. including the side lip. Its polyacrylate material and clockwise-spiral lip design are specified to support sealing at the transmission output area where fluid retention is critical.

It fits 1990-2002 Honda Accord, right; 1988-2001 Honda Prelude, right; 1997-1999 Acura CL, right; 1996-1999 Isuzu Oasis, right; and 1995-1998 Honda Odyssey, right. National 224066 is a direct-fit style option for drivers searching for a Honda Accord right transmission output shaft seal or an Acura CL manual transmission oil seal.

Common Problems This Seal Can Address

• Transmission fluid seepage at the output shaft
• Oil residue around the transmission housing bore
• Seal wear from shaft rotation and age
• Leak-related fluid loss at the right-side output area
• Service replacement for a worn manual transmission oil seal

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the bore and shaft surface thoroughly, and inspect for scoring, corrosion, or burrs that could affect sealing. Install the seal squarely to avoid lip damage, and confirm the clockwise-spiral lip orientation matches the application. Always compare the removed part to National 224066 and confirm right-side fitment for the specific vehicle and transmission.
