Product Details

SKF has a long history in seal engineering, including early development of integrated shaft seal designs and continued refinement of bonding and material selection. This timing cover seal is manufactured to specific design requirements so the sealing lip and material properties match the operating environment. For service work on vehicles such as the Jeep Wrangler, Toyota Tacoma, or Lexus GX460, the goal is to maintain lubricant retention and keep contaminants out of the sealed area.

Part number 17122 is listed across a broad range of model years, including 1994 through 2024, with rear and N/A positions shown in the fitment data depending on vehicle application. Use the exact vehicle listing to confirm the correct timing cover seal before installation.

What This Seal Helps Address

• Oil or fluid seepage at the timing cover area
• Contamination entering the sealed shaft interface
• Seal hardening or wear from age and heat cycling
• Loss of sealing integrity after service or disassembly
• Fitment issues when replacing a worn OE-style timing cover seal

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width against the removed seal before installation. Clean the sealing bore and shaft surface thoroughly, and inspect for scoring, corrosion, or debris that could affect sealing performance. Confirm the vehicle-specific position shown in the fitment data, especially on applications listed as rear or N/A. For service on Jeep Cherokee, Jeep Compass, and Toyota 4Runner applications, match the exact year and model before assembly.
