Chuck Removal
To remove the chuck:
1.DISCONNECT LATHE FROM POWER!
2.Place a sturdy piece of plywood under the spindle to protect the bed ways during the removal process.
3.Loosen the camlocks by turning the key counterclockwise until each of the cam lines are aligned with its corresponding spindle mark (see Figure 21).

Figure 21. Camlock is fully loosened when the cam
line is aligned with the spindle mark.
Tip: Camlocks can become very tight. A cheater pipe may be used as a last resort to add leverage when loosening. After loosening, you may need to wiggle the chuck key in the camlock to fully disengage the stud.
4.Using a dead blow hammer or other soft mallet, lightly tap around the outer circumference of the chuck body to loosen it from the spindle.
5.Remove the chuck from the spindle, using a light rocking motion to carefully slide the studs out of the cam holes.
—If the chuck does not immediately come off, rotate it approximately 60° and tap it again. Make sure all the marks on the cams and spindle are in proper alignment for removal.
