6. Place the clutch (#13) in a vise with non marring jaws or wrap a rag
around the clutch to prevent the clutch from being damaged. Apply
only enough pressure to prevent the clutch from turning when you
turn the lead screw using the hex handle. Do not apply so much
pressure that you crush or oblong the clutch. Turn the lead screw
clockwise until you feel the pin (#12) being depressed and popping
out of the drive notch. Continue turning the screw clockwise 180
degrees. If the nut and screw assembly has a pin that has been over
traveled it will be resting in the ramped slot in the clutch. You will
need to turn the screw counterclockwise to release the pin from the
over travel notch. Then turn the screw 180 degrees in a counter
clockwise direction.
7. Wearing gloves or wrapping a rag around the clutch, firmly grasp the
clutch and tap the threaded end of the lead screw on a soft, non
marring surface until the clutch spacer starts to slide off the screw.
When the clutch reaches the area where the pin (#12) and the springs
(#11) are contained by the clutch sleeve hold a rag or your hand over
that area so the pin and springs don't fly out. Continue to slide the
clutch sleeve down and remove it from the lead screw. If your vise has
built up excessive grit and chips it may take a few hard blows to get
the clutch off the screw.
8. If the pin and springs are still in the screw remove them at this time.
9. Slide the holding block assembly (#17) down and off the threaded end
of the lead screw. If the holding block binds in the area of the drive
slot use a file to smooth out any ridges on the slot edge.
