Manual Transmission Output Shaft Seal for Toyota and Suzuki

Timken 223540 is a manual transmission output shaft seal built for precise lubricant control at the transmission housing. It uses a reinforced outer case, a ribbed rubber inner diameter, and an internal contamination exclusion system to help maintain a clean sealing surface on applications such as Toyota Camry, Toyota Celica, and Suzuki Grand Vitara.

Key Features

• Precision sealing design helps retain transmission lubricant and block outside contaminants
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and promote positive seating
• Internal contamination exclusion system helps reduce debris intrusion at the seal lip
• Vent holes allow lubricant flow around the seal lip to help manage heat build-up
• N-Polyacrylate sealing material for transmission sealing applications
• Outside diameter: 2.176 in. / 55.27 mm; housing bore: 2.165 in. / 55.00 mm; shaft diameter: 1.378 in. / 35.00 mm; width: 0.315 in. / 8.00 mm

Detailed Description

This Timken manual transmission output shaft seal is engineered for vehicles that require a 35 mm shaft diameter and a 55 mm housing bore. It is a direct-fit sealing component for a wide range of applications, including Fits 1983-2001 Toyota Camry, N/A; Fits 1986-1999 Toyota Celica, N/A; Fits 1999-2005 Suzuki Grand Vitara, N/A; and Fits 1998-2004 Chevrolet Tracker, N/A. The seal design focuses on keeping lubricant inside the transmission while limiting contamination at the shaft interface. This part cross-references National 223540 for the same application.

Common Issues This Seal Can Address

• Transmission fluid seepage at the output shaft
• Contamination entering the seal area from road debris or grime
• Seal wear caused by minor shaft surface imperfections
• Heat-related seal deterioration around the lip area
• Leak concerns after transmission service or axle removal

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Inspect the output shaft for scoring, corrosion, or burrs that could affect sealing performance. Clean the bore thoroughly and install the seal squarely to avoid distortion of the outer case or sealing lip. For fitment-specific applications, confirm the vehicle position and transmission configuration before ordering, especially on Toyota Celica, Toyota Matrix, and Suzuki Vitara listings.

Quality Assurance

Timken oil and grease seals are built with precision sealing features and contamination control details to support reliable transmission service. The reinforced case and vented seal design reflect Timken’s focus on durability and controlled lubricant flow in demanding drivetrain applications.
