7.2.3 Clutch
The clutch sprocket (Fig. 9/k, 10/k)) is subject to
wear and must be checked regularly (at least once a
year).
CAuTION
Defective clutch sprocket
Defective sprockets may lead to the rotor shaft
breaking.
To check the clutch switch the motor (Fig. 9/m,
Fig. 10/m) off and ensure that it cannot be switched
on again.
C-VLR 60
Undo the screws (Fig. 9/s
4
) on the housing flange
(Fig. 9/n
1
). Remove the motor axially with the half of
the clutch on the motor side (Fig. 9/q) and suspend
with the lifting device. If the sprocket (Fig. 9/k) is
damaged or worn, then replace it.
C-VLR 100 - 251
Undo the screws (Fig. 10/s
5
) on the motor flange.
Remove motor and the clutch half (Fig. 10/q) from
the valve housing (Fig. 10/n
2
) axially and suspend
with a lifting device. If the sprocket (Fig. 10/k) is
damaged or worn, then replace it. The fan (Fig. 10/v)
should also be checked for damage from time to
time and replaced if necessary.
NotiCe
Frequent starting up and high ambient tem-
perature
The service life of the sprocket (Fig. 9/k, Fig. 10/k)
is reduced as a result of this.
Re-assemble in reverse order.
