SKF 21134 Automatic Transmission Oil Pump Seal

SKF 21134 is an automatic transmission oil pump seal built around precise dimensions and a nitrile sealing surface. It is intended for transmission service where the pump seal must retain fluid and help keep contaminants out.

  • Part number: 21134
  • Automatic transmission oil pump seal for transmission sealing systems
  • Outside diameter: 3.001 in.

Detailed Description

SKF 21134 is engineered as an automatic transmission oil pump seal with dimensions that matter during transmission rebuild and repair work. The 2.125-inch shaft diameter, 3.001-inch outside diameter, and 0.438-inch width help identify the correct seal for the application. For technicians searching for an SKF transmission oil pump seal, 21134 provides a direct reference point for matching the seal to the pump and shaft interface. This part cross-references Anchor 10293 for the same application.

SKF has a long history in seal development, and this seal reflects that focus on controlled material selection and precise fit. If you are servicing a transmission on a Ford, Chevrolet, or Dodge platform, verifying the seal dimensions against the original component is an important step before installation. Searches such as SKF 21134 automatic transmission oil pump seal, transmission pump seal 2.125 shaft diameter, and OE-style transmission seal replacement are common for this part.

What It Helps Address

  • Transmission fluid leakage at the oil pump seal area
  • Contamination entering the transmission through a worn seal
  • Seal wear from age, heat, and fluid exposure
  • Poor sealing after transmission service or rebuild
  • Dimension mismatch when replacing a worn pump seal

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation. Inspect the pump bore and shaft surface for scoring, corrosion, or debris that could affect sealing. Clean the sealing surfaces thoroughly and install the seal squarely to avoid distortion. For vehicle-specific searches, verify the application against the transmission build data for Ford, Chevrolet, or Dodge models before final assembly.

Quality Assurance

SKF manufactures seals to specific designs using premium materials and controlled production standards. The brand’s seal engineering background and long-term focus on lubricant retention and contamination control support consistent performance in transmission service.
