Disassembling and assembling the clamping force block
NOTE:
The base jaws (item 2), the chuck piston (item 3) and the housing
(item 1) are matched to each other. These parts cannot be
replaced individually. To replace these parts, ship the entire
clamping force block to SCHUNK along with a repair order.
Always transport the clamping force block without the changing
jaws. The KSP plus 250-BWM and KSP-LH plus 250-BWM have an
M10 threaded transport hole on the front of each base jaw for
mounting the T-handles with the set-screws included in the
accessory kit. Remove the T-handles before operating.
When replacing wearing parts (e.g. seals – for sealing kit lists, see
) adhere to the following order:
1 Pressurize the clamping force block at 6 bar until the jaws are in
the OPEN position.
2 Actuate the disengaging mechanics on the quick-change jaw
system and remove both changing jaws (WTR or WTG).
3 Remove the covering strip (7).
4 Remove the cylindrical screw (item 14) from the chuck piston.
5 Remove the pressure line.
6 Pull the plugs (item 8) out of the housing (item 1).
7 Loosen the screws (items 9, 19) and remove the clamping
system from the base plate or machine table. Air may escape at
this point.
