Detailed Description

Timken 223050 is engineered for manual transmission output shaft sealing where lubricant retention and debris control are critical. The seal’s precision design, reinforced outer case, and ribbed inner diameter support a stable fit on the shaft while helping maintain sealing contact across minor surface imperfections. With a 1.181-inch shaft diameter, 1.969-inch housing bore, and 1.978-inch outside diameter, this seal is sized for the listed applications and transmission service requirements. Timken 223050 is a direct-fit service part for select BMW and Subaru drivetrains, including BMW 325i, BMW Z4, Subaru Legacy, and Subaru Forester applications.

This part cross-references National 223050 for the same application.

What It Helps Address

• Transmission fluid leakage at the output shaft
• Contamination entering the transmission housing
• Seal wear from heat build-up around the lip
• Reduced sealing performance from minor shaft imperfections
• Installation damage to the seal case during service

Installation Notes and Tips

Verify shaft diameter, housing bore, and helix direction before installation. Clean the bore and shaft thoroughly, and inspect for scoring, corrosion, or wear that could affect sealing. Proper seating is important for BMW 430i, BMW 320i, BMW 128i, and Subaru Impreza manual transmission output shaft seal replacement jobs, especially where the original seal has been leaking or contaminated.
