Trouble, symptoms
Remedy
Excessive clearance in the bearings of the
front wheels.
Check and adjust the clearance in the
flange bearings.
Excessive clearance in the bearings of the
HPS hydraulic cylinders.
Replace the worn-out parts.
Excessive wear and ply separation of front tyres:
Toe-in is misadjusted or disturbed.
Adjust the toe-in as described in Section
“Adjustments”.
Tyre inflation pressure does not corre-
spond to that recommended.
Keep the pressure in the tyres according to
the recommendations (see Section “Ag-
gregating the Tractor with Agricultural Ma-
chines and Implements”).
The FDA is all the way operated in the
forced engagement mode.
Check the FDA engagement and disen-
gagement. If any faults will be detected,
eliminate them.
Steering control
Excessive force to be applied for turning the steering wheel:
1. No or insufficient oil pressure in the hy-
draulic system of the steering wheel due
to:
1. The oil pressure in the hydraulic system
of the steering wheel shall be 140...155 bar
(at the stop):
Bleed air from the hydraulic system.
●
the relief valve of the metering pump has
hung up in the open position or adjusted to
low pressure.
*●
Wash the relieve valve and adjust it to
the pressure of 140...145 bar
.
●
the feeding pump is faulty or designed
for counter-clockwise rotation.
●
repair or replace the pump.
2. Excessive friction or jamming in the me-
chanical components of the steering col-
umn.
2. Eliminate the friction in the steering col-
umn:
●
reduce the tightening of the upper nut;
●
lubricate the rubbing surfaces of the plas-
tic bushings;
●
eliminate the contact of the universal joint
with the walls of the steering column
bracket.
3. Excessive torque of turning of the FDA
reduction gears.
3. Repair the FDA.
The steering wheel rotates without turning the steerable wheels:
1. No oil in the tank.
1. Fill in the tank with oil up to the required
level and bleed air from the hydraulic sys-
tem.
2. The relief valve is set to the pressure ex-
ceeding the set point of the anti-hammer
valves.
*2. Adjust the setting of the relief and anti-
hammer valves.
3. When disassembling and reassembling
the non-return valve, the ball was not refit-
ted.
*3. Refit the ball of the non-return valve.
The seals of the hydraulic cylinder piston 4. Repair or replace the hydraulic cylinder.
