The technical condition of the steering can be approximately determined by the amount of free play (play) of the steering wheel
Maintenance of the steering includes its inspection, checking the fastening of the units, the free play of the steering wheel, checking and adjusting the axial play in the propeller bearings, the clearance in the meshing of the steering gear, as well as lubrication work according to the car’s lubrication chart.
Steering mechanism and steering column: 1 - steering wheel; 2, 25 - steering column switches; 3 - retaining ring; 4 - washer; 5 - bearing; 6 - plastic bearing bushing; 7 - ignition switch (lock); 8 - lower part of the steering column casing; 9 - steering column shaft; 10 - cardan joint; 11 - wedge; 12 - nut; 13 - intermediate steering shaft; 14 - intermediate shaft seal; 15 - cardan joint bearing; 16 - bearing needles; 17 - retaining ring; 18 - steering mechanism; 19 - bipod shaft; 20 - universal joint grease nipple; 21 - steering column pipe; 22 - bracket; 23 - handle of the steering column fixation mechanism; 24 - upper part of the steering column casing; 26 - steering wheel fastening nut; 27 - decorative steering wheel trim; 28 - ball nut screw; 29 - top cover; 30 - adjusting gasket; 31, 39 - sealing rings; 32 - ball nut; 33 - ball nut; 34 - nut; 35 - bipod; 36 - cover; 37 - foam ring; 38 - retaining ring; 40 - bipod shaft bearing; 41 - ball nut screw bearing; 42 - bracket; 43 - crankcase; 44 - filler plug; 45 - oil seal; 46 - protective cover
When inspecting the steering, you need to check the fastening of the parts.
All nuts and bolts securing the steering wheel, steering column, steering gear housing, steering shaft, bipod and steering linkage arms must be securely tightened to the torques specified below.
Then you should check the free play of the steering wheel in the position of the front wheels corresponding to the vehicle moving in a straight line.
The amount of free play of the steering wheel should not exceed 25° for GAZ-2705 and GAZ-2705 Combi (and for buses - 20°).
If, after checking all steering elements and eliminating identified faults, the free play of the steering wheel is 25° for GAZ-2705 and GAZ-2705 Combi (for buses - 20°) or more, then it is necessary to adjust the tightening of the screw bearings and the gearing steering mechanism.
Adjusting the steering wheel
Adjusting the position of the steering column must be done after adjusting the driver's seat relative to the control pedals.
To do this you need:
- - turn handle 23 towards you and upward, loosening the fixation of the steering column;
- - set the steering wheel in a comfortable position;
- - fix the selected position of the steering column by turning handle 23 down and away from you.
If it is necessary to adjust the column fixing mechanism, you must:
- - remove the lower casing 8 by unscrewing two screws and freeing it from the lower clamp;
- - remove the upper casing 24, bringing the column as close as possible to the driver;
- - loosen the lock nut and tighten the bolt to a torque of 9.0-12.5 Nm (0.9-1.25 kgf/m);
- - fix the lock nut with a torque of 14-18 Nm (1.4-1.8 kg/cm), preventing the bolt from unscrewing;
- - check column fixation;
- - install the upper and lower casings.
