Manual Transmission Output Shaft Seal for BMW and Nissan

Timken 223520 is a manual transmission output shaft seal built for rear-position applications on select BMW and Nissan vehicles. It uses an S-Nitrile sealing material and a precision sealing design to help retain lubricant while keeping contaminants out of the transmission.

Key Features

  • Manual transmission output shaft seal for rear applications
  • S-Nitrile construction for sealing performance and durability
  • Reinforced outer case helps resist installation damage
  • Ribbed rubber inner diameter helps seal minor shaft imperfections and promote seating
  • Internal contamination exclusion system helps block debris that can lead to leakage
  • Vent holes promote lubricant flow around the seal lip to reduce heat build-up
  • Dimensions: 1.980 in. outside diameter, 1.378 in. shaft diameter, 1.969 in. housing bore, 0.315 in. width

Detailed Description

Timken 223520 is engineered for rear manual transmission output shaft service where consistent sealing is critical. The seal’s reinforced outer case supports installation, while the ribbed inner diameter helps maintain contact on shafts with minor wear or surface variation. With a contamination exclusion system and vented design, this seal is built to help maintain lubricant control under operating heat and road exposure. This part cross-references BBB Industries (e.g., 13885, 13933) for the same application.

  • Seal damage during installation

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation: 1.378 in. shaft diameter, 1.969 in. housing bore, and 0.315 in. width. Clean the sealing surface and inspect the shaft for scoring or excessive wear before pressing the seal into place. Confirm rear-position application and match the vehicle exactly to the listed fitment for BMW M5, BMW M6, BMW 7 Series models, BMW Z3/Z8, and Nissan Frontier or Xterra.
