Disassembling and assembling the piston
The item numbers specified for the corresponding individual
components relate to chapter drawings.
•
For chuck sizes 165 and 200
the screw (item 10) is screwed in
directly to the piston (item 3) and secured using the pin (item
67). Items 9, 70 and 80 are no longer required.
•
Unscrew the stop pins (item 40) from the piston.
•
Unscrew and remove the screw (item 33) and take off the
safety ring (item 38), then remove the thrust washer (item 32).
•
Remove the screws (item 64), take off the plate (item 12), and
pull the pendulum body (item 5) out of the piston (item 3).
•
The screw (item 66) is glued into the pendulum body (item 5)
such that the connecting member (item 11) is pivot-mounted
with 0.2 mm axial play. Only remove the connecting member
(item 11) if disassembly is required.
•
Undo the securing screws (item 67) such that the flange (item
9) or the screw (item 10) can be removed from the piston (item
3).
Degrease and clean all parts and check them for damage or wear.
Only use genuine SCHUNK spare parts when replacing damaged
parts.
Before assembly, grease well with LINOMAX plus special grease
paste.
The piston is assembled in the same way but in the reverse order.
