8.8 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.8.8.1) to dismount the retaining washer (Fig.8.8.2). Take out the screws on the buffers and the nuts of
the
elastic
element
(Fig.8.8.3;Fig.8.8.4).
Remove
the
elastic
element from the QC
plate (Fig.8.8.5). While
the
holder
is
dismounted
(Fig.8.7.6;Fig.8.8.7)
clean the parts and
replace the defective
with
new
ones.
Assemble the holder
with new buffers with
new screws and new
elastic element. Put the
retaining
washer
(Fig.8.8.8) and push the
locking pin (Fig.8.8.9).
This will prevent the fall
of the washer when
mounting the holder on
the machine.
Make sure the four bolts holding the adaptor (Fig.8.8.12) are reliably tighten. Mount the holder on the machine using the
same socket as mentioned in 8.6 (Fig.8.8.10;Fig.8.8.11). The retaining washer fits into the central hole C of adaptor and the
four bolts into the thread holes Т (Fig.8.8.12). The
holder is centered on the outside diameter of the
adaptor. Ensure the connection of the holder on
the forehead 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.8.8.2) 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. Fig.8.8.13 is 3-d section view of the
holder, showing its parts. The numbering is the
same as in Spare parts.
