8.5 DISASSEMBLING AND
MOUNTING TOOL HOLDER TO
CHANGE BUFFERS AND ELASTIC
ELEMENT
When the TOOL HOLDER is
disassembled you can change
defective parts – elastic element,
buffers, etc.
Lift the locking pin (Fig.8.5.1) to
dismount the retaining washer
(Fig.8.5.2). Take out the screws on
the buffers and the nuts of the
elastic element (Fig.8.5.3;Fig.8.5.4).
Remove the elastic element from
the QC plate (Fig.8.5.5). While the
holder
is
dismounted
(Fig.8.5.6;Fig.8.5.7), clean the parts
and replace any defective ones
with new ones. Assemble the
holder with new buffers, new
screws, and new elastic element.
Replace the retaining washer
(Fig.8.5.8) and push the locking pin
(Fig.8.5.9). This will prevent the
washer
from
falling
while
mounting the holder on the
machine.
Make sure the four bolts holding the adaptor
(Fig.8.5.12) are reliably tighten. Mount the holder
on the machine using the same socket as
mentioned in 8.2 (Fig.8.5.10;Fig.8.5.11). The
retaining washer fits into the central hole C of
adaptor and the four bolts into the thread holes Т
(Fig.8.5.12). The holder is centered on the outside
diameter of the adaptor. Ensure the holder is
properly connected to the plate of the adaptor and then
tight evenly the four bolts.Tightening force of the bolts
has to be 22...25N.m(16...18 ft/lbs). Mounting the holder
without retaining washer (Fig.8.5.2) is
INADMISSIBLE
because the security system preventing the separation of
part of the holder in case of broken buffers and elastic
element will not function!You can change the butterfly
of the holder without dismounting the holder of the
machine.
