TROUBLE, EXTERNAL MANIFESTATION
Non-conformance of the direction of the guide wheel turn to that of the steering wheel rota-
tion
Wrong connection of the cylinder outlets of the meter-
ing pump to turning cylinder.
HYDRAULIC MOUNTED SYSTEM
А. Without hydraulic lift
No lifting of the mounted attachment with an agricultural implement
No pressure in the hydraulic system:
Sticking of the bypass valve;
Remove the valve parts, wash them and refit into
the body. The valve shall move freely.
Clogging of the safety valve;
Disassembly the safety valve, wash its parts and
reassemble it. Adjust the valve operation pressure
within 18…20 MPa.
Maladjustment of the governor control rod length.
Adjust, as described in the section “Adjustments”.
No forced lowering of the mounted attachment
Maladjustment of the governor control rod.
Adjust as described in the section “Adjustments”.
Too slow lifting of the mounted attachment with an agricultural implement
Air inflow into the hydraulic system.
Detect the inflow place and eliminate the defect.
Heavy oil leakages in the pump.
Check the pump capacity; replace the pump, if nec-
essary.
Oil foaming in the tank and splashing through the breather
Air inflow into the system via suction line.
Tighten the fastening and replace the suction con-
nection gaskets, if necessary.
Air inflow through the self-moving cuffs of the oil
pump of the hydraulic system of the mounted at-
tachment or pump of the SS system.
Check the condition of the self-moving cuffs and re-
place, if necessary.
Increased oil heating during the operation of the system
Insufficient quantity of oil in the tank.
Add oil to the tank to the upper mark of the oil meter
The oil pipelines are bent or rumpled.
Eliminate the dents or replace the oil pipeline.
Unblocking of the parts of the stem valve of the dis-
tributor.
The agricultural implement is not held in the transport position
(After lifting to the transport position, the implement is lowered spontaneously)
Oil leakage over sealing rings of the cylinder piston
or rod;
Replace the sealing rings of the cylinder piston.
The slide valves or borings in the distributor body.
During the power control, the tillage depth variation exceeds the agrotechnical norms, the engine
rotational speed drops in case of overloads
The correction rate cock is shut.
Increase the automatic correction rate by turning
the handwheel counter-clockwise.
The central rod of the mounted attachment is set to
the lower hole of the shackle.
Set the central rod to the upper hole of the shackle
and, if the maximum tillage depth is insufficient – to
the middle hole.
Maladjustment of the power sensor.
Adjust the power sensor and then the power rod
(see section “Adjustments”).
Maladjustment of the power rod.
Adjust the power rod (see section “Adjustments”).
Loosening of the tightness of the split hubs of the
levers on the intermediate shaft.
Tighten the bolts of the lever hubs on the intermedi-
ate shaft.
Distorted holes on the plough frog and frame con-
nected by the toe bar, insufficient stiffness of the
plough frame.
Repair the plough to ensure the frame stiffness and
its connection with the frog.
