InMotion WS471766 Manual Transmission Input Shaft Seal - Front Inner

Manual Transmission Input Shaft Seal

InMotion WS471766 is a nitrile seal built to maintain a tight barrier against contaminants and fluid loss in the transmission sealing system. Its dimensions and material selection support a precise fit where the shaft and housing measurements must align correctly.

Key Features

• Nitrile sealing material for dependable fluid control.
• Inside diameter of 1.25 in. with a 2 in. housing bore.
• Compact 0.25 in. thickness and 0.25 in. width.
• Part number WS471766 for accurate ordering and identification.

Detailed Description

This InMotion transmission seal is engineered for applications that require a secure seal around the input shaft area. The nitrile construction helps resist contamination while maintaining contact at the sealing surface, which is important for reducing leaks and protecting internal components. For buyers searching for a manual transmission input shaft seal for Triumph TR6, Triumph TR250, or Ford Bronco applications, WS471766 provides a fitment-specific replacement option with clearly defined dimensions.

The part number WS471766 should be verified against the original seal dimensions before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Transmission fluid seepage at the shaft seal area.
• Contamination entering the sealed housing.
• Wear caused by an aging or hardened seal.
• Loss of sealing integrity from incorrect dimensions.

Installation Notes and Tips

Confirm shaft diameter, housing bore, and seal thickness before installation. Clean the sealing surface and inspect the shaft for scoring or wear that could affect sealing performance. Fitment includes 1966 Ford Bronco, Front Inner; 1967-1971 Ford Bronco, Front Inner with Spicer 30-AF Axle; 1968-1973 Triumph TR6, N/A with Standard CD Transmission; 1969-1971 Triumph TR250, N/A with Standard CD Transmission; and 1974-1976 Triumph TR6, N/A with Standard CF Transmission.
