Whirlpool WP8577376 Washer Genuine OEM Transmission Shaft Seal

Factory replacement transmission stem / agitator shaft seal for select Whirlpool-built top-load washers.

Product Overview

WP8577376 is a Genuine Whirlpool OEM washer shaft seal. Whirlpool describes it as a washing machine transmission stem seal, while Sears identifies it as an agitator shaft seal.

The seal helps prevent wash water from leaking between the tub mounting stem and the agitator drive shaft, protecting the transmission/drive area from moisture.

Quick Answer

WP8577376 is the current Genuine Whirlpool OEM replacement for several older washer shaft and center-post seals. It is commonly used on older Whirlpool-built direct-drive top-load washers.

Common Problems This Part May Fix

  • Water leaking around the agitator or center-post area
  • Moisture reaching the transmission or drive system
  • Worn, cracked, hardened, or missing shaft seal
  • Leak discovered during tub or transmission service
