Good To Know

Q: What are the signs of a failing deck spindle? A: Excessive noise, blade wobble, or a deck that cuts unevenly usually indicate bearing wear inside the spindle. Check for play by hand with the engine off before ordering.

Q: Is this an original MTD or Craftsman part? A: No, this is an aftermarket deck spindle assembly that cross-references the listed OEM numbers. Confirm your deck model and part number before purchase.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
