Flathead screwdrivers - Help pry up ring ends if pliers alone don't work. Use multiple sizes.
Masking tape - Protects spindle surface from plier damage during removal.

Understand Snap Ring Structure

Snap rings have small protruding ends that fit into grooves around a spindle motor.
Rings compress when inserted in the groove and spring back to lock in place.
Rings must be compressed again for removal from the groove.

Clean spindle and locate snap ring groove. Check for corrosion.
Apply masking tape around spindle next to the snap ring.
Lubricate the snap ring with penetrating oil to aid removal.

Compress Snap Ring with Pliers

Position plier tips on ring ends and squeeze handles to compress.
Maintain tight grip so ring doesn't slip from pliers.
Equal force on both sides allows even compression.

Extract Snap Ring

Pull pliers away from groove to extract compressed snap ring.
If the ring catches, use a screwdriver to pry up the caught end while pulling.
Remove ring completely and inspect for damage.

Conclusion

Removing snap rings takes patience and care. Following proper technique prevents damage during the process. Always use snap ring pliers and allow lubrication time before attempting removal. With practice, necessary snap ring removal and installation can be performed smoothly.
