Removing the steering gear

To do this, do the following:

- remove the cotter pin and unscrew the wedge nut on the steering mechanism, knock out the wedge, eliminating its deformation, and remove the cardan shaft yoke from the mechanism shaft;

- unscrew the bipod mounting nut and remove the bipod from the steering gear sector shaft with a puller 7823-6092;

Puller 7823-6092 for removing the bipod from the steering gear

- unscrew the five nuts securing the steering gear bracket to the frame side member, and remove the steering gear with the bracket; remove the bracket from the steering gear.

Disassembly

To disassemble, do the following:

GAZ-2705 steering gear

- drain the oil from the crankcase of the steering wheel through the filler plug 4

- clamp the steering mechanism in a vice by the tide under the crankcase mounting hole and thoroughly clean all surfaces from dirt;

- remove two plugs from the crankcase;

- remove covers 17, 19 and sponge seal 16 from the sector shaft;

- straighten the holes on the bearings 15 of the shaft-sector with a beard;

- remove the bearings 15 of the shaft-sector one by one with a puller without shocks and distortions, eliminating the spilling of the rollers.

Moving bearings to the other end of the shaft or mixing the rollers of one bearing with the rollers of another bearing are not allowed.

- remove the shaft-sector 3 and sealing rings 13;

- unscrew the bolts securing the top cover of the crankcase and remove the top cover along with the gaskets;

- press out the stuffing box, bearing race from the top cover, having removed the preliminary sealing ring and gaskets 5;

- remove screw 2 complete with nut;

- press out the remaining outer race of the propeller bearings.

Do not press out the outer races of the propeller bearing from the crankcase and the top cover unnecessarily.

Inspection

The parts of the dismantled steering mechanism should be washed in kerosene or other liquid that facilitates the removal of grease, dirt and metal wear particles from the parts.

Before assembling the steering gear, inspect all of its parts to determine if worn parts need to be replaced.

Steering gear housing

If cracks and breaks are found, the crankcase must be replaced.

Screw with steering gear nut.

If dents appear on the surface of the screw or if it jams when turning the screw in the nut, it should be replaced as an assembly with the nut.

Shaft-sector

If there are cracks and dents on the working surfaces of the shaft, the shaft-sector must be replaced.

Bearings

Bearings must be washed in clean kerosene and blown out with compressed air.

If the bearings have cracks, wear of the raceways and balls, cage cracks, then such bearings must be replaced.

Sealing rubber rings

If the sealing rings have lost their original shape or have tears and cuts, then the rings must be replaced.

Assembly

To assemble, do the following:

- lubricate the working surfaces of the steering gear parts with a thin layer of grease;

- press the screw bearing cage into the steering gear housing as far as it will go and install the sealing rings;

- press the screw bearing cage, oil seal into the top cover and install the sealing ring;

- check the quality of pressing the bearing cages with a feeler gauge;

- install the screw with the nut and bearings in the crankcase;

- install and bolt the top cover of the steering mechanism by adjusting the tightening of the screw bearings.

The bolts of the top cover must be tightened to a torque of 24-36 Nm (2.4-3.6 kg/cm);

- install the shaft-sector into the crankcase, while the middle tooth of the nut should fall into the middle cavity of the shaft-sector;

- install the assembled bearings;

- adjust the engagement of the sector shaft with the nut;

- perform subassembly in the reverse order of disassembly;

- install the steering mechanism on the car.

The bolts of the bracket to the steering gear must be tightened to a torque of 44-62 Nm (4.4-6.2 kg / cm), the nuts of the bracket to the side member - to a torque of 28-36 Nm (2.8-3.6 kg /cm);

- install the cardan shaft yoke on the steering shaft, drive the wedge into the yoke and tighten it with a nut to a torque of 1 8-25 Nm (1 8-2.5 kg/cm).

Place the flat and spring washers under the nut on the machined sideawn on the fork, cotter wedge;

- install the bipod on the shaft-sector of the steering mechanism and secure it with a nut, the tightening torque is 105-1 40 Nm (10.5-14 kg / cm).

Removing the cardan shaft of the steering wheel

To remove the cardan shaft, you must:

- remove two cotter pins of the hinges, unscrew the nuts securing the wedges, knock out the wedges, remove the caps and remove the cardan shaft with the seal;

- remove the cotter pin on the cardan shaft hinge, unscrew the wedge nut, knock out the wedge and remove the cardan shaft hinge.

Disassembling the cardan shaft

In the process of disassembly, you must:

- clean the cardan shaft joint from dirt and oil;

- remove the retaining rings of the bearings of the cross;

- press out the bearings of the cross on a press or in a vice with a bronze certificate, the outer diameter of which is slightly smaller than the hole in the fork.

To do this, the mandrel must be installed on the bottom of the needle bearing housing and the opposite bearing is pressed out.

Turn and press out the other bearing, setting the reference to the end of the cross spike;

- turn the shaft 1/4 turn and press the bearings out of the lugs of the second fork in the same sequence;

- remove the cross.

Rinse all parts of the cardan joint in kerosene and check their condition.

Replace worn parts.

Similarly, the cardan shaft hinge mounted on the steering shaft is disassembled.

Gimbal assembly

To assemble, do the following:

- lubricate the bearings and the cross with a thin layer of grease, insert the spikes of the cross into the eye of one of the forks so that the oiler does not close the cheek of the fork;

- using a mandrel, first press one bearing into the cardan yoke, and then the second;

- install retaining rings;

- turn the cardan shaft ¼ turn and in the same sequence press in and fix the other two bearings in the lugs of the second crosspiece with retaining rings;

- lubricate the bearings of the cross through a grease fitting;

- after installing the wedge, install the washers and the nut on the machined surface of the fork.

Splint the wedges;
- tighten the wedge nuts to a torque of 12-18 Nm (1.2-1.8 kg / cm).
The cardan shaft hinge mounted on the steering shaft is assembled in the same way.< /p>

Removing the steering wheel

To remove the steering wheel you need:

- remove the steering gear cover;

- unscrew the steering wheel nut, remove the lock washer;

- make a mark on the steering wheel hub and on the end of the shaft to determine their relative position;

Steering wheel puller

- remove the steering wheel with a puller.

Installation

To install the steering wheel you need:

- install the steering wheel according to the previously marked marks on the steering wheel hub and on the end of the shaft;

- install the lock washer and secure the steering wheel. The tightening torque of the nut must be 65-80 Nm (6.5-8.0 kg/cm);

- install the pad on the steering wheel.
