Timken 710415 Manual Transmission Output Shaft Seal - Rear

Manual Transmission Output Shaft Seal for Ford and Mercury

Timken 710415 is a manual transmission output shaft seal built for rear-position applications on select Ford and Mercury vehicles. It is designed to retain lubricant inside the transmission while helping block dirt and debris from entering the sealing area.

Key Features

• Precision sealing design helps control oil and grease leakage
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections
• Internal contamination exclusion system helps reduce debris intrusion
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup
• Timken 710415 for manual transmission output shaft service

Detailed Description

Compatible With rear manual transmission applications on 1988-1999 Ford F-250, 1999 Ford F-250 Super Duty, 1988-1997 Ford F-150, 1992-1996 Ford Bronco, 1988-1990 Ford F-350, 1988-1989 Ford E-150 Econoline, 1988-1989 Ford E-150 Econoline Club Wagon, 1988-1989 Ford E-350 Econoline, plus 1989-1995 Ford Thunderbird and 1990 Mercury Cougar. Timken 710415 is engineered to help maintain proper transmission fluid control at the output shaft, where wear, contamination, and heat can affect seal performance. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Seal Helps Address

• Transmission fluid seepage at the output shaft
• Contamination entering the rear seal area
• Seal wear from heat buildup and lubricant breakdown
• Minor shaft surface imperfections that affect sealing
• Damage during seal installation

Installation Notes and Tips

Verify rear output shaft fitment before installation and inspect the shaft surface for scoring, corrosion, or burrs. Clean the sealing bore and surrounding area thoroughly, and install the seal squarely to avoid distortion. Confirm the transmission application matches your vehicle, including Ford F-150, Ford Bronco, and Ford F-250 rear manual transmission configurations listed for this part.

Quality Assurance

Timken oil and grease seals use reinforced construction and contamination-control features to support consistent sealing performance in drivetrain service.
