Characteristics for differentiating
between tensioners
4180 182 7600
Left:
previous version 4180 182 7600
Right:
new version 4180 182 7601
The tensioners can be identified according to these
markings:
–
Part number on the part
–
Routing of the throttle cable at the outlet of the
new tensioner (arrow)
3.1.2
Spare parts/service notes
When supplied as spare parts, the new throttle
cables are supplied with the new tensioner. Thus the
new throttle cables can also be used with older
machines.
New throttle cables must always be paired with a
new tensioner.
Previous throttle cables can be used both with the
previous or new tensioners.
The previous tensioner 4180 182 7600 can only be
combined with the previous throttle cables.
For replaceability in previous machine versions,
reworking of the spacer flange may be required as
needed, see b 3.2.

3.2
Spacer flange
Parallel to the new throttle cables, the gap for
routing of the throttle cable has been enlarged on
spacer flange 4180 120 2303. The part number of
the spacer flange remains unchanged. The new
spacer flange can also be used with older machines.
Service note for the spacer flange
The dimension (b) in the gap is required for routing
the throttle cable with the longer plastic tube.
.
Check gap width (a) before installing a new
throttle cable
If the dimension (a) is between 0.095 and 0.102 in.
(2.4 and 2.6 mm), then:
.
Rework the part – widen the gap so that the
width (b) is between 0.106 to 0.118 in. (2.7 and
3.0 mm)
If the dimension is between 0.106 to 0.118 in.
(2.7 and 3.0 mm), no rework is necessary.
