If all the pulley units have to be replaced, dismount motor base disc and motor. Before removing the belt unscrew the
central pulley (so it does not turn while unlocking) (Fig.8.12.7) (Fig.8.12.8). Pull the central pulley off (Fig.8.12.9).
Unlock bolts (Fig.8.7.10) and take more off (Fig.8.12.11). Unlock retaining shaft/bearing (Fig.8.12.12). Take away the filling
ring (Fig.8.12.13). Now the motor base disc is unlocked, the only way to dismount it is to press it out on a bearing press
(Fig.8.12.14) (Fig.8.12.15). Dismounting the driving pulley: take the top screw out to release the bushing (Fig.8.12.16), push
the bushing together with the washer up (Fig.8.12.17), push washer down of the bushing., take bushing out (Fig.8.12.18),
push key out (Fig.8.12.19), now the washer releases (Fig.8.12.20), dismount sealer cap (Fig.8.12.21), the pulley can be
released with two crowbars; do not use excessive force (Fig.8.12.22) (Fig.8.12.23), push the sealer cap to dismount
(Fig.8.12.24), by mounting back the sealer cap, secure with sealant, center the holes to mount the pulley.
Change the two other
pulleys as earlier described
in the chapter, best when
the motor base disc is
dismount to change the
roller units too. Unlock the
nut on top (Fig.8.12.25). The
pulleys can be released with
two crowbars; do not use
excessive force (Fig.8.12.26) (Fig.8.12.27).
