3. Unscrew the six bolts (4), remove the
lock plate (6) and remove the shank
(5).
4. Install another shank into the spline hole
and install the plate (6), screwing in the
bolts (4) to a torque of 50 Nm.
5. Assemble the other parts in the order
reverse to disassembling.
c) lubricate the shaft and pipe of the tel-
escopic joint of the cardan drive with
solid oil. Install the cardan drive joint
to the PTO shank, secure it in the fix-
ing groove. Make sure that the forks
(1) of the joints of intermediate (tele-
scopic) shaft lay with the ears (2) in
the same plane. Failure to observe
this requirement results in overloads
of the cardan drive and PTO.
d) install the casing of the agricultural
machine driveshaft;
e) after installing the cardan drive, make
sure, that the elements of the cardan
drive telescopic joint do not stop against
the tractor in the extreme positions of the
machine; the minimum overlap of the
cardan drive telescopic part must be 110
to 120 mm as in case of a lesser value
the drive may disengage.
f) adjust the safety coupling of the agri-
cultural machine by changing the
length of the spring (1). It must be ad-
justed so that in case of overloads the
cam clutches 2 and 3 rotate each rela-
tive to the other. A too strong tension
of the spring results in maloperation of
the clutch and overloads of the cardan
drive and PTO.
g) engage the PTO independent drive at
minimum engine speed or when the
engine is off. Engage the synchronous
PTO drive when the engine is running
by gradually engaging the clutch.
h) disengage the PTO when making
turns with the machine (for trailer ma-
chines) as well as when lifting the ma-
chine to the transportation position (for
mounted and semi-mounted ma-
chines);
