8.6 DISMOUTING TOOL HOLDERS TO CHANGING V-RINGS AND FELT RINGS
To check or replace the buffers and the elastic elements, the tool holders have to be dismounted.
You will need a 13mm deep metric socket with an outside diameter of no more than 3/4in to unscrew the four bolts
(Fig.8.6.1) and remove the holder (Fig.8.6.2) When the tool holder is dismounted, you can change the sealers (V-Ring
and Felt-Ring).
By loosening four Hex cap flange bolts (Fig.8.6.3) the adaptor comes loose. Unscrew the six screws of the cap
(Fig.8.6.4) holding the felt-ring. Take out the Felt-Ring, adaptor and V-Ring.
Mount the V-Ring with the smallest lip of the V to the inside (Fig.8.6.5) - simply push the V-Ring so the top is on the
same level as the pulley top (Fig.8.6.6). Then take the adaptor and push the V-Ring down with the adaptor (Fig.8.6.7).
The lowest lip of the V-Ring should only barely touch its gliding surface. Mount the adaptor and the Felt-Ring on top
(Fig.8.6.7). Close the sealers with the cap (Fig.8.6.8) and screw the bolts. Always use the original bolts. Do not push the
V-ring down with fingers.
When the tool holder and adapter are dismounted, you
can change the top key transmitting the movement to
the planetary chain
.
8.7 DISASSEMBLING AND MOUNTING TOOL HOLDERS TO CHANGING BUFFERS AND ELASTIC ELEMENT
When the
TOOL HOLDER is disassembled you can change defective parts – elastic element, buffers, etc.
Lift the locking pin (Fig.8.7.1) to dismount the retaining washer (Fig.8.7.2). Take out the screws on the buffers and the nuts of the
elastic element (Fig.8.7.3; Fig.8.7.4). Remove the elastic element from the QC plate (Fig.8.7.5). While the holder is dismounted
(Fig.8.7.6; Fig.8.7.7), 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.8.7.8) and push the locking pin (Fig.8.7.9). This will prevent the
washer from falling while mounting the holder on the machine.
