d) Take the old V-belt off and replace it with a new one. Original V-belt marking is
OPTIBELT X13x1335 Ld 6T6K , ord. No. 184 608 . It is also possible to use an
equivalent V-belt made by other manufacturers at a size of A13x1300 Li (Li=internal
length) or A53“ (53“ is the external length La). However, the belt must be made
without rubber on sides! Only such a belt model will guarantee that the V-belt is not
extended and the blade drive start is smooth at engaging the clutch.

Should another than the original recommended type and size of the belt be used, the
machine manufacturer does not answer for correct and full functioning of the drive!
e) After you put the new V-belt on the pulley, insert the V-belt into the groove in the
tightening pulley and fully tighten the bolt on the pulley arm.
f) Put the engine back in place. Pins in the driving belt pulley must fall into holes in the
rubber element on the driven part of the clutch, installed on the gearbox. Bolt the
engine with three M8 nuts with flat washers. Screw the accelerator lever back onto the
handlebars and put the red ball back on the accelerator lever.
g) Put the V-belt into the groove in the belt pulley on the engine.
h) Check the operation of the tightening pulley and adjustment of guide lamination. With
the lever on the right handlebar grip fully pressed down, the pulley must ensure
sufficient belt tension (spring on the cable being extended by about 10 mm as
compared with loose condition). Possible corrections are to be made by means of
adjustment bolt No. 1 (see Fig. 10). With the lever switched off, the pulley must be
tilted away from the longitudinal machine axis at an angle of max. 0 - 5° = with the
belt convex side being approx. 1,5 – 2,0 cm from the bottom of the tightening pulley
(see Fig. 9). The wire in the Bowden cable of the tightening pulley must exhibit no
slackness. In the case that the adjustment bolt is completely screwed out and it is
necessary to tighten the V-belt, the spring on the cable can be hooked into the front
hole on the arm of the tightening pulley (see Fig. 9 bottom, note: this connection can
be used already from the manufacturer) and belt tension can be adjusted once again.
Guide lamination on the right side of the machine must be parallel to the belt and at a
maximum distance of 1 – 2 mm from the belt convex side.
i) Mount the front belt guide back to its original position and mount back the plastic belt
cover.

If the gearbox disassembly from the machine frame occurs, the reverse assembly
must be made with a proper axial alignment of the gearbox and engine shafts. This
is why the operation should be made by an authorized service workshop which has
to have available an original and by manufacturer approved centring fixture.
