TRANSMISSION BOX BELTS - FIGURE 183
The three drive belts (item 1) on the transmission box
are kept tight by a floating tightener (item 2). This tight-
en has a limited stroke. To avoid any slipping, a gap
of approximately 1/16” to 3/32” (1.5 to 2.5) should be
maintained between the spring coils. This adjustment is
made by tightening the stop nut (item 3).
The limitation gap bolt (item 4) must be adjusted so as to
leave a 1/8” (3) gap between the tightening arm and the
tip of the bolt (item 5).
To replace the three belts (item 1), refer to Figure 180:
FAN BELT REPLACEMENT.

REVERSE, NEUTRAL AND FORWARD SPEEDS
POSITIONS - FIGURE 184
To adjust shifting on the main transmission box:
1. Dismantle the rod (item 1) by removing the pins and
spacers (item 8) to free the cylinder (item 2).
2. Screw the bolt (item 3) completely. Rotate the trans-
mission sheave in a FORWARD motion so that the
speed shift arm (item 4) swings as much as pos-
sible towards the bolt head (item 3). When you hear
a ”CLICK” it means that the REVERSE position is
obtained.
3. Unscrew the bolt (item 3) and keep a 1/8” (3) clear-
ance with the back of the shift arm.
4. Lock the bolt in place with the self-locking nut (item
5).
5. To adjust the FORWARD speed, proceed as for the
REVERSE position using the bolt (item 6) until you
hear a ”CLICK”.
6. Swing the shift arm to the NEUTRAL position and
then bring the rod (item 6) back up by putting back
the pin and washers (item 8) as before.
7. Refer to page 162 for the detector positioning
sensor (item 7) adjustment.
WARNING: Make sure that all movements of parts
in the Forage Harvester has stopped before servi-
cing or repairing the machine.
