Timken 223010 Steering Gear Sector Shaft Seal - Front or Rear

Timken 223010 Steering Gear Sector Shaft Seal

Timken 223010 is a steering gear sector shaft seal built for precise lubricant control and contamination exclusion. It uses an S-Nitrile sealing material, a reinforced outer case, and a ribbed inner diameter to help maintain a secure seal on the shaft.

Compatible With applications such as 2011-2019 Mitsubishi Outlander Sport, 2013-2018 Subaru BRZ front, and 2001-2010 Kia Optima front, this seal also serves many Toyota, Hyundai, BMW, Volkswagen, and other steering gear applications. The Timken 223010 seal is engineered for direct replacement use where the original sector shaft seal has worn, hardened, or begun leaking.

• S-Nitrile construction for sealing performance in steering gear service
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter seals minor shaft imperfections
• Internal contamination exclusion system helps block debris entry
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup
• Dimensions: 1.663 in. outside diameter, 1.181 in. shaft diameter, 1.654 in. housing bore, 0.276 in. width
• CW clockwise helix type

Detailed Description

Timken 223010 is a steering gear sector shaft seal designed to retain lubricant inside the steering gear while keeping dirt and other contaminants out. The seal’s reinforced outer case supports installation durability, while the ribbed inner diameter helps create a tighter seal on shafts with minor wear. Its vented design allows lubricant circulation around the lip, which helps manage operating heat in the sealing area. This part cross-references National 223010 for the same application.

Use Timken 223010 when servicing steering gear leaks on vehicles such as Mitsubishi Outlander Sport, Subaru BRZ, and Kia Optima, or on other listed applications including Hyundai Santa Fe, Toyota Camry, BMW 535i, and Volkswagen Golf. The part number 223010 is also a useful reference when matching OE-style steering gear sector shaft seals across multiple import and domestic platforms.

What It Helps Fix

• Steering gear lubricant leakage at the sector shaft
• Contamination entering the steering gear housing
• Seal wear caused by shaft surface imperfections
• Heat-related seal deterioration in the sealing area
• Loss of steering gear fluid retention during service

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Timken 223010 measures 42.24 mm outside diameter, 30.00 mm shaft diameter, 42.00 mm housing bore, and 7.00 mm width, with a clockwise helix. Clean the bore and shaft thoroughly, inspect for scoring or corrosion, and install the seal squarely to avoid lip damage.

For fitment confirmation, match the vehicle application exactly. Examples include Fits 2011-2019 Mitsubishi Outlander Sport, N/A; Fits 2013-2018 Subaru BRZ, Front; and Fits 2001-2010 Kia Optima, Front.
