• Vent holes promote lubricant flow around the seal lip to reduce heat buildup
• Timken part number 340151 for direct reference and ordering

Detailed Product Overview

This steering gear sector shaft seal is designed around precise dimensions: 1.567 in. outside diameter, 1.125 in. shaft diameter, 1.561 in. housing bore, and 0.250 in. width. Those measurements matter when servicing Ford steering gear assemblies because a correct seal fit helps maintain lubricant inside the gear while keeping road grit and other contaminants out. Timken 340151 is also cross-referenced to Quality-Built 11081 and SKF 18757 for the same application.

Vehicle coverage includes 1974-1982 Ford E-100 Econoline, 1975-1982 Ford E-150 Econoline, 1975-1982 Ford E-250 Econoline, 1980-1982 Ford E-350 Econoline, 1975-1982 Ford F-100, 1975-1982 Ford F-150, 1975-1982 Ford F-250, 1980-1982 Ford F-350, and 1968-1973 Ford Thunderbird steering gear applications. Timken 340151 is a practical replacement choice when servicing Ford steering gear sector shaft sealing surfaces that match the listed dimensions and design notes.

What It Helps Fix

• Steering gear oil or grease leakage at the sector shaft
• Contamination entering the steering gear housing
• Seal wear caused by minor shaft surface imperfections
• Heat-related seal deterioration from poor lubricant circulation
• Improper sealing on Ford steering gear assemblies with the listed dimensions

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Inspect the sector shaft for scoring, corrosion, or wear that could affect sealing performance, and clean the bore thoroughly so the reinforced outer case seats evenly. Use care during installation to avoid distorting the seal lip or damaging the outer shell. Confirm the steering gear design matches the Ford Design or Saginaw Design notes shown in the fitment data before assembly.

Quality Assurance
