2.   Exhaust muffler

From machine number X 28 323 087 the muffler will
be secured with IS M6x25 spline screws instead of
the previous IS M6x90x30 spline screws.
The original stud 0000 953 1024 will be replaced by
a new higher strength version 9121 347 1370.
Two new M6 flange nuts, with a larger flange
diameter, are used to mount the muffler to this stud.
The previously welded cover plate and the spark
arresting screen are now secured with one IS M4x6
spline screw in each case. The B 4.2x9.5 self-
tapping screw used to secure the spark arresting

screen and strap 4201 148 3001 used with the long

screws have been deleted.

Parts availability

In order to simplify stockkeeping and guarantee inter-
changeability, only the new version of the muffler will
be supplied as a replacement in future (with spark

arresting screen and all necessary mounting hard-
ware). In those countries where a spark arresting
screen is mandatory, it is only necessary to fit the
screen according to the illustrated instructions
supplied with the assembly.

Modification to be introduced from machine number X 28 323 087

Remarks
1) Original version of part no longer available from factory
2) Original version of part remains available for older machines and other models

3.   Bearing with guard

3.1 V-belt guard, screws - 19 mm across flats,
    eccentric adjuster

The original sheetmetal V-belt guard was replaced

some time ago with a new version made of polymer.
This change helps save weight (approx. 0.2 kg/
7 oz.) and improves functionality. The head size of

the three mounting screws was changed from
13 mm to 19 mm across flats at the same time and
the eccentric adjuster was modified.

The new eccentric adjuster is now rotated with the
blade of the combination wrench (slot or Torx
recess) instead of the previous captive 13 mm nut.
The head size of the M10x18 mounting screw for
the cutting wheel has also been changed from
13 mm to 19 mm across flats.

Parts availability

All versions of the "bearing with guard" supplied

from now on will include a polymer V-belt guard,
the associated mounting screws (19 mm a/f) and

the new eccentric adjuster.
To ensure interchangeability the new polymer V-
belt guard 4201 700 8114 will be supplied with two
washers. These washers must be fitted on older

machines which have mounting screws with 13 mm
head (see illustration).

3.2 Cast arm

    (mounting screw with 19 mm head)

The M10x35 hex. head screw (17 mm across flats)

previously used to mount the cast arm to the
crankcase will be replaced by a M10x40 hex. head
screw (19 mm a/f).

7.   Elbow fitting on fuel tank

The position of the thread runout for the elbow
fitting in the fuel tank was modified from machine
number X 27 928 356. This change has made the
gaskets that were used as packing unnecessary.
As before, the elbow fitting is screwed in as far as
the stop until the retaining lugs engage. The O-ring
9645 945 4050 seals the joint in this position.
The elbow fitting 4201 007 1032 will be supplied
with three gaskets so that it can still be used for
older machines.
