Answer Hello Jake, As per the service guide for model GTW460ASJ0WW; The auger assembly needs to be removed first to access the agitator bolt. To remove the auger, it must be twisted off of the agitator base clockwise. This can be done either using the screwdriver method or the strap wrench method. Screwdriver Method Removal 1. Locate the small protrusion near the bottom of the auger that mounts to the agitator base. 2. Rotate the auger until the hole lines up with the protrusion. This is the location where the inner wall of the auger is thin, so the screwdriver can go through it the easiest. NOTE: The hole is located approximately 3 inches from the bottom edge of the auger fin. 3. Using a thin shank screwdriver, twist it through the hole in the auger. Using the counterforce weight of the basket and the screwdriver handle as a lever, rotate the basket to the left slightly and then with a jerk motion, pop the auger free from the agitator base. Be sure to hold the screwdriver as level as possible. Strap Wrench Method Removal 1. Slide the strap wrench around the bottom of the auger (just below the movable part of the auger) and tighten it until it clicks into place. Important: Ensure the strap wrench is positioned where it will tighten when twisting the auger to the right. 2. Hold the strap against the handle of the wrench to prevent it from coming loose around the auger. 3. Using the counterforce weight of the basket, rotate the basket to the left slightly and then with a jerk motion, pop the auger free from the agitator base. Be sure to hold the strap wrench as level as possible. 4. Remove the 7/16 hex bolt and slide the impeller off of the shaft. The splined coupler is part of the impeller. Important: The impeller bolt WH02X24374 should be replaced any time it is removed for service, and torqued to 100 in. pounds. Read More... Answered by AppliancePartsPros.com | Thursday, May 31, 2018
