Detailed Description

This SKF 6729 seal is engineered around exact dimensional requirements so the shaft interface can maintain a tight seal under steering pump operating conditions.

Common Problems This Seal Can Address

  • Power steering fluid leaking from the pump shaft area
  • Contamination entering the steering pump through a worn shaft seal
  • Loss of hydraulic pressure caused by seal wear
  • Steering pump service needs on 1958 Chrysler Imperial, New Yorker, Newport, or Town & Country
  • Seal deterioration from age, heat, and fluid exposure

Installation Notes and Tips

Verify shaft diameter and seal bore dimensions before installation. Inspect the pump shaft surface for scoring or wear, since a damaged shaft can shorten seal life. Clean the sealing area thoroughly and confirm the seal is seated squarely during assembly. For fitment-specific service, confirm the vehicle is a 1958 Chrysler Imperial, New Yorker, Newport, or Town & Country with Thompson Pump equipment.
