and/or the levers encounter additional re-
sistance when moving or being shifted,
due to the lack of lubrication in the joints,
severe fouling and/or butting-up (contact)
against adjacent parts (units) of the trac-
tor, etc.
7.6.8. ADJUSTING THE FDA
UNIVERSLA-JOINT DRIVE
The maintenance of the universal-joint
drive consists in adjusting the safety
coupling in the intermediate support and
checking the side play in the universal-
joint bearings.
The safety coupling should be adjusted
to transfer a torque within 40
…80 kgf
•
m
(400
…800 N
•
m). Coupling adjustment is
achieved by tightening nut (2) (see Fig.
57) of the rear tail-end of the intermedi-
ate support shaft, until the transfer of a
required torque is attained.
Check regularly the universal-joint trun-
nion bearings for side play. If side play is
detected, dismantle the joint and check
the condition of bearings and trunnions;
replace worn-out parts, if any. When in-
stalling the stuffing box, press glands
down until they rest against the bearing.
The universal-joint shaft is dynamically
balanced. Dismantle the universal-joint
shaft only in case the occasion requires.
On replacing parts when in service
—
tubes together with joint forks and flange
— the shaft in assembly with both joints
should be dynamically balanced, with
plates welded at both ends of the tube.
The imbalance should not exceed 55
g
•
cm. DO NOT rotate universal-joint
shafts using tyre levers, wrenches and/or
other accessories, to avoid damage to
their packings, grease fittings and/or
breakdown of universal-joint trunnions.

7.6.9. THE FORE AXLE
Adjusting the Steering Tie-Rod
Articulated Joints
Every 125 hours of operation check the
articulated joints by rocking the articulat-
ed joints by hand or turning the steering
wheel.
Fig. 58
To adjust the steering tie-rod articulated
joint, proceed as follows:
а) disconnect locking wire (2) (see Fig.
58) from the rod end
(3)
;
b) turn down plug (1) be means of a
wrench so that to take up the gap in
the joint;
c) lock the plug with locking wire.
