Disassembling and assembling the chuck
WARNING
The lathe chuck may only be disassembled once it has been
uninstalled (see Mounting the lathe chuck).
• You can leave the base jaws (item 2) in the chuck. Move them
to the outermost permissible position. To do this, push the
piston (item 3) to its front end position.
• Remove the screws (item 43) and use the threaded extraction
hole to push off the center sleeve (item 4) away from the chuck
body (item 1), and then pull it out completely.
• Remove the screws (item 42/44) from the mount (item 7).
• Mark the position of the mount (item 7) in relation to the chuck
body (item 1).
• Loosen the screws (item 40/41) several thread turns and
hammer gently on the screw heads using a rubber mallet. This
allows the mount (item 7) to be released from the centering for
the chuck body (item 1). Remove the screws and take off the
mount.
• Remove the safety bolt (item 14) with compression spring (item
35) and spring bolt (item 13).
• Use a suitable tool to push out and remove the jaw-change bolt
(item 8) with the balls (item 37) through the bore hole for the
safety bolt. Check the seal (item 33) for damage and wear, and
replace it if necessary.
• Pull the piston (item 3) together with the wedge bar set (item
9) out of the chuck body (item 1). The individual wedge bars
(item 9) are identified in position in the chuck body (item 1) in
accordance with the numbering on the perimeter. The piston
has a point marking at the radial front side on the piston
diagonal pull. This is assigned to base jaw guide 1 during
assembly.
• Push the base jaws (item 2) out of the chuck body (item 1).
• Check the seal (item 31) in the piston (item 3) for the center
sleeve (item 4) and the sealing ring (item 32) for the draw tube
for damage and wear, and replace it if necessary.
A wedge bar (item 9) consists of nine parts in total. Spring tension
pre-loads the pressure bolt (item 12) and the pressure pieces (item
