To replace PTO drive end, fulfill the
following operations:
1. Screw out two bolts and remove a cap
(1).
2. Unscrew four nuts (3) and remove
guard (2).
3. Screw out six bolts (4), remove plate
(6) and dismount the drive end (5).
4. Install another drive end into spline
opening and install the plate (6).
5. Assemble remaining details in the
reverse sequence.
c) Lubricate the shaft and tube of cardan
drive telescopic joint with solid oil.
Install cardan drive joint on PTO drive
end, fasten it securely in fixation
groove. Make sure that eyes (2) of joint
forks (1) of intermediate (telescopic)
shaft lie in one plane. Failure to satisfy
mentioned requirement causes cardan
drive and PTO overloading;
d) Install cardan shaft guard of agricultural
machine;
e) After cardan drive installation make sure
that there is no thrusting of telescopic
connection elements of cardan drive,
when machine is in its extreme positions
towards the tractor; minimum overlapping
of cardan drive telescopic part should be
110-120 mm, as drive discoupling is
possible if overlapping length is less.
Safety clutch spring length (1) of agricultural
machine should be adjusted in such a manner to
provide turnover of cam clutches (2 and 3)
against each other in case of overloading.
Excessive spring tightening leads to clutch
malfunction and cardan drive and PTO
overloading.
Actuate separate PTO drive at minimum engine
speed or when the engine is shut down. Actuate
synchronous PTO drive with running engine,
while smoothly engaging clutch coupling.
When operating tractor without use of PTO be
sure to set PTO control lever into “PTO-off”
position, set shifting clutch of two-speed PTO
drive into position 1 (540 rpm), and set selector
lever of separate-synchronous PTO drive into
middle (neutral) position.
