Inner Spindle Removal
Turn off all power to the machine before continuing.
• Remove the upper housing cover, and drive belt.
• Remove the driven sprocket.
• Remove the cutterhead and chip guard.
• Crank spindle up to its full up position.
• Insert a rod or punch through this opening and into the upper adjusting nut. Holding the cutterhead,
loosen this nut by turning it counter-clockwise. Remove nut, index bushing (7246C), key (6062), and
two Belleville spring washers (7052).
• Thread upper adjusting nut back onto inner spindle to keep the spindle from falling out, after
throwback nut is unthreaded.
• Take a rod or punch and insert it into one of the holes in the outside of the throwback nut. This nut is
located between the bottom of the outer spindle and the lower flange of the inner spindle.
• Turn the nut clockwise to loosen. As you back off the nut, tap on top of the inner spindle with a soft
mallet. Do this until the nut is threaded out of the outer spindle.
• Place something under inner spindle, then unthread the upper adjusting nut.
• Slowly lower the inner spindle out of the outer spindle.
• Upper Spindle Bearing Removal:
• Use a puller or a long bar from inside the outer spindle, to carefully remove the upper bearing.
