Manual Transmission Shift Shaft Seal for OE-Style Sealing

Timken 710243 is a manual transmission shift shaft seal built to help retain lubricant at the shift shaft while keeping dirt and debris out of the transmission. It is a direct-fit sealing component for select Mazda, Honda, Chevrolet, Oldsmobile, and Nissan manual transmission applications.

Compatible With 2014-2018 Mazda 3, 2014-2018 Mazda 6, and 2013-2018 Mazda CX-5 applications, this seal supports clean, stable shift shaft sealing in service environments where leakage control matters. Timken 710243 is also listed for additional manual transmission applications across older Honda, Chevrolet, Oldsmobile, and Nissan models.

Key Features

• Manual transmission shift shaft seal for lubricant retention
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter seals minor spindle imperfections
• Internal contamination exclusion system helps block debris entry
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Timken part number 710243 for accurate ordering and service lookup

Detailed Description

Timken 710243 uses a precision sealing design to help prevent oil and grease escape from the shift shaft area while limiting contaminant intrusion. The reinforced outer case adds durability during installation, and the ribbed inner diameter helps maintain sealing contact on shafts with minor surface variation. Vent holes around the seal lip support lubricant circulation, which helps manage heat at the sealing surface. This makes the Timken 710243 a practical choice for manual transmission service on Mazda 3, Mazda 6, and Mazda CX-5 models, along with other listed applications.

What It Helps Solve

• Transmission fluid seepage at the shift shaft
• Contamination entering the manual transmission housing
• Seal wear caused by heat build-up at the lip
• Poor sealing on shafts with minor imperfections
• Leak-related drivability concerns during manual transmission service

Installation Notes and Tips

Inspect the shift shaft, bore, and surrounding sealing surface before installation. Clean away old seal material, dirt, and lubricant residue so the new seal seats evenly. Confirm the seal orientation before pressing it into place, and avoid nicking the sealing lip or outer case during installation. Verify the transmission is filled to the correct fluid level after service.

Quality Assurance

Timken oil and grease seals are engineered with precision sealing features, reinforced construction, and contamination control details to support dependable service life in transmission applications.
