Product Details

SKF 14703 is designed for manual transmission applications where the input shaft area must stay sealed against lubricant loss and outside contamination. SKF has a long history in seal engineering, and this part reflects that experience with application-specific construction and material selection. It is a direct-fit style seal for a range of vehicles, including Dodge Ram 2500 and Dodge Ram 3500 models with the 5600 transmission, plus select Nissan, INFINITI, Mitsubishi, and Lincoln applications. The part number 14703 is also commonly referenced in cross applications for the same service position.

What It Helps Fix

• Transmission fluid seepage at the input shaft area

• Leak-related maintenance on Dodge Ram 2500 and Dodge Ram 3500 5600 transmission service
• Rear transmission seal replacement on select Nissan and INFINITI models

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and transmission application before installation. Clean the sealing bore and shaft surface thoroughly, and inspect for scoring or wear that could affect seal life. For best results, install the seal squarely to avoid distortion of the sealing lip. Verify the vehicle listing carefully for year, model, position, and notes such as 5600 transmission or rear application details.
