SKF 13900 Differential Pinion Seal

SKF 13900 is a differential pinion seal built for driveline sealing at the pinion shaft. With a nitrile sealing surface and precise dimensions, it helps maintain lubricant retention where the pinion enters the differential housing. This SKF differential pinion seal is a practical choice for service work on applications such as Ford F-150 and Chevrolet Silverado driveline repairs when the original seal shows wear.

Key Features

  • Part number: 13900
  • Outside diameter: 2.720 in.
  • Shaft diameter: 1.375 in.
  • Width: 0.313 in.
  • Nitrile sealing surface for driveline sealing applications
  • SKF engineered seal design for differential service

Detailed Description

SKF 13900 is a differential pinion seal designed around the shaft diameter, outside diameter, and width needed for a proper housing fit. The nitrile sealing surface is selected for sealing performance in driveline environments where gear oil must stay contained and road contaminants must stay out. SKF has a long history in seal engineering, and this part reflects that focus on material selection and dimensional accuracy. If you are servicing a Ford F-150 or Chevrolet Silverado differential, verifying the pinion seal dimensions against the original part is an important step before installation. This part cross-references 594449R91 for the same application.

Common Problems This Seal Helps Address

  • Gear oil leakage at the differential pinion area
  • Contamination entering the differential housing
  • Seal wear from age, heat, and driveline movement
  • Noise or driveline service concerns tied to low lubricant level
  • Maintenance replacement during differential repair work

Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width before installation to match the original seal specification. Inspect the pinion yoke and sealing surface for grooves, corrosion, or damage that can affect sealing performance. Clean the housing bore thoroughly and install the seal squarely to avoid distortion. For Ford F-150 and Chevrolet Silverado service, compare the removed seal to SKF 13900 and verify the application details before reassembly.

Quality Assurance

SKF manufactures seals to defined design and material standards for long service life in automotive applications. The brand’s seal engineering background supports consistent fit and sealing performance in differential service.
