12.4 Removing the PTO shaft
1. Move the PTO shaft guard into installation
position (Fig. 89).
2. Remove the grease nipple (Fig. 90/1) in the
connection fork (Fig. 90/3) of the PTO shaft
(Fig. 90/2).
3. Remove the shear bolt (Fig. 90/4) between
the fork flange of the PTO shaft and the
flange of the gearbox input shaft.
4. Pry the connection fork off of the gearbox
input shaft using a flat bar.

While prying the connection forks off
of the gearbox input shaft, repeatedly
turn the PTO shaft.
12.5 Shear-off safety devices for
PTO shafts
The separately packaged screws M8 x 30 A2-
70, are replacement shear bolts (Fig. 89/1) for
fastening t
he universal joint fork of the PTO shaft
to the flange of the gearbox input shaft. Always
use grease when fastening the PTO shaft to the
gearbox input shaft.

12.6 Ventilate the friction clutch
After long periods of disuse and before using
it for the first time, "ventilate" the friction
clutch as follows:
1.
Remove the friction clutch from the gearbox
input shaft.
2. Relieve the springs (Fig. 91/1) by unscrew-
ing the nuts (Fig. 91/2).
3.
Crank the clutch by hand. This will eliminate
distortion caused by rust or moisture be-
tween the friction surfaces.
4. Tighten the nuts until the pressure springs
have the specified installation length of a =
1 in / 26.5 mm.
5. Push the friction clutch onto the gearbox
input shaft and fasten it in place. The fric-
tion clutch is now ready to be used again.
High humidity, large amounts of dirt or cleaning
the machine with high-pressure cleaners in-
crease the likelihood of thermal distortion of the
friction linings.
