Fig. 7.2. The steering mechanism: In — an edge on the top cover; With — risk at a screw end face; 1 — картер; 2 — the screw with a ball nut; 3 — a shaft-sector; 4 — a stopper of a jellied aperture; 5 — adjusting linings; 6 — a nut; 7 — шплинт; 8 — a plug; 9 — a cover; 10 — a wedge; 11 — a sealant of a steering shaft; 12 — карданный a shaft; 13 — a sealing ring; 14 — a lock ring; 15 — an external ring of the bearing of a shaft-sector; 16 — a shaft-sector sealant; 17 — a cover; 18 — сошка; 19 — a lateral cover; 20 — a stopper

Adjustment of bearings to spend at occurrence of an axial or radial backlash in bearings of the screw 2 (fig. 7.2) to be convinced available these backlashes, it is necessary:

- To turn a steering wheel on 21/2 turns from position of rectilinear movement in any party;

- To shake the screw of the steering mechanism for the fixed plug a hand; if thus the screw has axial or radial moving (люфт plugs concerning a cover of the steering mechanism) screw bearings should be regulated.

Adjustment make in the following sequence:

• to disconnect сошку 18 and a plug of a shaft 12 steering wheels;

• to turn on bolts of fastening of the steering mechanism to an arm and to remove the steering mechanism from the car;

• to merge oil through an aperture closed by a stopper 4;

• to take out two stoppers 20 on картере;

• to remove two covers 17 both 19 and a spongy sealant 16 shaft of sector;

• to remove a lock ring 14;

• to straighten бородком лунки on bearings of a shaft-sector and to remove their stripper, having excluded blows and warps on the bearing;

• to remove a shaft-sector 3;

• to turn on bolts of fastening of the top cover картера, to uncover and take out one of adjusting linings 5;

• to establish a cover картера into place and to check up the moment of turn of the screw in bearings. The moment should be 0,4—0,8 Н�м (4,0—8,0 кгс�см). Thus it should not be felt люфт the screw;

• to establish a shaft-sector 3 and bearings, having greased landing surfaces and sealing rings with oil for the steering mechanism. At installation, bearings should be directed эксцентриситетом downwards (the shaft-sector is as much as possible removed from a ball nut). Warps at assemblage are not supposed. Jamming of bearings on a shaft-sector or картере testifies to a warp or wrong orientation эксцентриситетов bearings;

• to adjust gearing in steam a nut-sector;

• to fix from a procollar shaft-sector bearings, having unbent a fillet on bearings in apertures on картере;

• to make assemblage of the steering mechanism in return sequence;

• to establish the steering mechanism on the car;

• to fill in oil;

• to establish сошку 18 and a plug of a shaft 12 (at installation of a wedge 10 nut 6 and washers should be from outside processed end face on a plug 8).
