fit great, easy to install. Only problem was the blade shaft and washer was a different diameter than my old one. Had to take time to go to hardware store to find nut and washer to fit after install. Remommend sending hardware with it.

These spindle assemblies fit well and work well, I have purchased and worn them out numerous times. The aluminum housing always wears out, to bad they can't make them with a stronger material. The trick is to keep them lubricated and never run blades that are badly worn because when the blades are out of balance it will wear out the spindles faster.

They need to change the aluminum on the lower part of this casting. I have to keep changing them because they wear out.

Seems to fit and work just fine. Better if it used same blade retainer nut and washer as original. Mounting holes in flange not tapped but that is understandable with as many models as the spindle fits.

Perfect fit. Received quickly. Good job.
