8.6 REPLACING THE CLUTCH
In case the electric clutch has to be replaced, remove the engine (see previous
chapter) and lay it on its side with the oil drainage up (Fig. 8.6.1)
and loose
the front nut to dismount the clutch (Fig. 8.6.2 and Fig. 8.6.3 ).
Reassemble in the same manner. Do not forget to mount back the washer on the
shaft
(Fig. 8.6.4). The torque on the front nut (Fig. 8.6.3) to mount the pulley and clutch
should be 70 Nm or 52 ft lbs(Fig. 8.6.2 and Fig. 8.6.3).
8.7DISMOUNTING TOOL HOLDER 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 deep metric socket 13mm with outside diameter not more than 3/4in to unscrew the four bolts (Fig.8.7.1) and
remove the holder (Fig.8.7.2)
When the tool holder is dismounted, you can change the sealers (V-Ring and Felt-Ring).
By loosening four Hex cap flange bolts (Fig.8.7.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.7.4)
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 inside (Fig.8.7.5) just push the V-Ring so the top is on the same
level as the pulley top (Fig.8.7.6). Then take the adaptor and push the V-Ring down with the adaptor (Fig.8.7.7).
The lowest lip of the V-Ring should only barely touch its gliding surface; also never push the V-Ring down with
fingers. Mount the adaptor and the Felt-Ring on top (Fig.8.7.7). Close the sealers with the cap (Fig.8.7.8) and
screw the bolts. Always use the original bolts.
Do not push the V
‐
ring down with fingers.
