Timken 223608 Manual Transmission Output Shaft Seal - Front or Rear

Manual Transmission Output Shaft Seal for Mitsubishi and Toyota

Timken 223608 is a manual transmission output shaft seal built for direct-fit service in a wide range of Mitsubishi, Dodge, Ford, Plymouth, and Toyota applications. It is designed to retain transmission lubricant at the output shaft while helping block dirt and debris from entering the case.

With fitment covering Mitsubishi Montero, Montero Sport, Mighty Max, and Outlander applications, as well as Toyota Supra and several Mitsubishi-based Dodge and Ford models, this seal supports common front and rear manual transmission service needs. Timken 223608 is a practical replacement when the original seal shows wear, leakage, or contamination damage.

• Reinforced outer case helps resist installation damage and improve durability
• Ribbed S-Nitrile inner diameter helps seal minor shaft imperfections and promote seating
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to reduce heat buildup
• Helix type: CCW counter-clockwise
• Dimensions: 2.055 in. outside diameter, 1.417 in. shaft diameter, 2.047 in. housing bore, 0.394 in. width

Detailed Description

Timken 223608 is a manual transmission output shaft seal engineered for vehicles that use Mitsubishi-based transmission designs. It is commonly selected for front and rear service on Mitsubishi Montero, Mitsubishi Montero Sport, Mitsubishi Mighty Max, Mitsubishi Outlander, Toyota Supra, Dodge Ram 50, Dodge Raider, Ford Ranger, Ford Bronco II, Ford Explorer, Ford Aerostar, and related applications listed in the fitment data. This part cross-references National 223608 for the same application.

The seal uses S-Nitrile material for oil and grease resistance, while the ribbed inner diameter helps maintain contact on shafts with minor wear. The reinforced outer case supports installation, and the contamination exclusion features help reduce the chance of debris-related leakage in manual transmission service.

What It Helps Fix

• Transmission fluid leaking from the output shaft area
• Contamination entering the manual transmission through a worn seal
• Heat-related seal wear from poor lubricant control
• Leakage caused by minor shaft surface imperfections
• Seal damage during removal or installation

Installation Notes and Tips

Confirm housing bore, shaft diameter, width, and helix direction before installation. Timken 223608 measures 52.20 mm outside diameter, 36.00 mm shaft diameter, 52.00 mm housing bore, and 10.00 mm width, with a CCW helix.
