How do you remove the spindle key?
How do you remove the spindle key?
Place the assembly over the key, and then thread the bolt into the shaft as far as it will go. Spin the nut downward against the block. Then use a wrench to apply enough force on a nut to remove the key from the shaft. If you apply enough downward movement, the key will be extracted.
What’s the best way to remove a pulley?
Drop cap screws through the 7/16 holes and screw in with a good amount of torque. ( judgement call ). Allow the plate to rest on the shaft end. With a torch begin heating the outer periphery of each pulley edge so the hub will expand before the shaft expands. That heat will expand the hub while the hub can still be touched with your fingers.
Can a pulley be removed from a tapered shaft?
The tapered shafts present a unique challenge in that the pulley or sprocket, whose bores are also tapered, is pressed onto the tapered shaft ( Photos 1 and 2 ), usually by nut or bolt in the end of the shaft. To remove the pulley or sprocket, the friction lock the pulley or sprocket has on the shaft must be broken.
How big is the nut on a cleaning fan shaft?
As an example, a pulley on the end of a cleaning fan shaft has a three-quarter-inch nut to tighten the pulley to the shaft, but the torque spec for the nut is only 80 foot pounds. Other situations where sprocket or pulley loosening might occur will call for hammer seating the sprocket or pulley.
Why is the pulley on the left not working?
In Photo 3, the pulley on the left does not have a collar or shoulder on the shaft to stop the inward movement of the pulley when the bolt is tightened. The pulley on the right presents a problem because you cannot see behind the pulley to determine if there is a shoulder or collar.

How can I remove this stuck nut on my riding?
Use that to prevent the pulley from turning. Probably, you’ll have to dedicate one hand to that while loosening. Look carefully at the exposed thread. The photo is not clear enough for me to be sure, but it looks like it might be reverse threaded. So to loosen, apply force clockwise (as seen looking down the bolt).
