InMotion WS714670 Manual Transmission Output Shaft Seal

Manual Transmission Seal Overview

The InMotion WS714670 is a manual transmission output shaft seal built for heavy-duty applications that need a secure barrier against contaminants and fluid loss. It uses polyacrylate construction and precise dimensions to help maintain a tight seal in compatible New Process 4500HD transmission setups.

Key Features

• Polyacrylate seal material for durable sealing performance.
• Precision sizing with a 2.5 in. inside diameter and 3.5 in. housing bore.
• Designed to maintain a reliable barrier against debris and moisture.
• Fits manual transmission applications using the New Process 4500HD transmission.
• Part number WS714670 for easy identification and ordering.

Detailed Description

This InMotion transmission seal is engineered to help protect internal drivetrain components by maintaining a consistent seal at the output shaft area. The polyacrylate material and measured thickness support a controlled fit, while the 3.504 in. outside diameter helps the seal seat properly in the housing. It is a practical replacement choice for Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and GMC Sierra 3500 applications listed with the New Process 4500HD transmission. The WS714670 part number should be matched carefully to the transmission configuration before installation.

What It Helps Address

• Transmission fluid seepage at the output shaft seal area.
• Contamination from dirt and moisture entering the seal interface.
• Wear-related sealing loss in high-load manual transmission service.
• Fitment issues when replacing a seal on New Process 4500HD-equipped trucks.

Installation Notes

Confirm the transmission model and seal dimensions before installation. Clean the sealing surface thoroughly and inspect the shaft and housing bore for wear, scoring, or damage that could affect sealing performance. Verify the application against the vehicle listing for WS714670 before final assembly.
