Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Basket does not spin or spins inconsistently
• Agitator does not move during the wash portion of the cycle
• Loud grinding, roaring, or other abnormal noise during operation
• Oil or grease leakage from the gearcase area
• Clothes remain unusually wet at the end of the cycle

Check Before Replacing

• With power disconnected, check whether the inner basket feels unusually loose when rotated by hand; excessive looseness can indicate transmission or bearing wear but is not conclusive.
• Observe whether the washer fills, drains, and powers the motor while the agitator or basket fails to move; inspect other drive components before condemning the gearcase.
• Inspect the visible gearcase area for oil leakage or signs of seal failure.
• Before replacing the gearcase, inspect accessible drive components such as the splutch, drive pulley, belt, or coupling for visible cracking, breakage, or abnormal wear, because those components can produce similar no-agitate or no-spin symptoms.

Installation Notes

• Disconnect electrical power and turn off the washer water supply before servicing.
• The gearcase is located beneath the washer tub and requires removal or disassembly of surrounding drive and tub components for access.
• Use caution when handling the assembly because it is heavy; follow the model-specific service documentation and use appropriate lifting assistance.
• Replace all removed parts and panels before reconnecting power or operating the washer.
• Verify the replacement part against the washer model and existing part identification before installation.
