The steering mechanism - general information, removal, major maintenance and installation

General information

On Citroёn Xantia cars the steering mechanism of reechny type which, depending on a model complete set, can be equipped by the hydraulic booster is used.

The executive cylinder of system of hydrostrengthening of a wheel is established between the case of reechny transfer and steering draft.

The steering mechanism with a manual drive


1 — Carter of reechny transfer 2 — the Remote plug in thickness of 9 mm 3 — the Bolt of fastening of the steering mechanism	4 — the Internal hinge of fastening of steering draft 5 — the Lock-nut (45 Nanometers) 6 — the Nut of a spherical finger of a tip of steering draft

The steering mechanism with a hydraulic drive


1 — Carter of reechny transfer 3 — the Bolt of fastening of the steering mechanism (70 Nanometers) 4 — the Internal hinge of fastening of steering draft 5 — the Lock-nut (45 Nanometers) 7 — the Valve regulator	8 — Fastening of the hydraulic cylinder on assembly of the steering mechanism (90 Nanometers) 9 — the Emphasis (the course limiter) steering drive (not on all models) 10 — Fastening of the hydraulic cylinder on steering draft (60 Nanometers) 11 — the Remote washer in thickness of 3 mm

Removal

The divider of the spherical support, new nuts of spherical fingers of hinges of steering drafts and new coupling bolt of fastening of an intermediate shaft of a steering column to a driving gear wheel of reechny transfer is required. On the models equipped with the power steering also new sealing elements of shtutserny sockets of hydraulic tubes be required.

Fastening of an intermediate shaft of a steering column to a driving gear wheel of reechny transfer

1 — the Nut of a coupling bolt
2 — the Coupling bolt
3 — the Fixing collar (to unclench in the directions specified by shooters)

PERFORMANCE ORDER

1. On the models equipped with system of hydrostrengthening of a wheel, dump pressure in hydraulic system (see. Head Uniform hydraulic system), then turn a steering wheel from an emphasis against the stop for the purpose of an oporozhneniye of the executive cylinder of a hydraulic actuator.
2. Prop up protivootkatny boots back wheels, then поддомкратьте a front of the car and establish it on props. Remove forward wheels.
3. Make sure that naves of forward wheels are developed in rectilinear situation.

4. On models with a manual drive of the steering mechanism disunite spherical hinges of fastening of three drafts of a drive of gear shifting.

5. On the models equipped with system of hydrostrengthening of a wheel, release shtutserny sockets and disconnect from a case of reechny transfer hydraulic tubes. At once закупорьте the open ends of tubes and reception unions of the steering mechanism for the purpose of hit prevention in dirt system.

6. From one of boards of the car weaken and partially unscrew a nut of a spherical finger of the hinge of fastening of steering draft on stupichny assembly. By means of a divider of spherical support liberate a finger from the reception nest, then finally unscrew a nut.

7. Repeat procedure of division of the spherical hinge for the second steering draft from an opposite board of the car.
8. Remove thermofilters from assembly of the steering mechanism.
9. Under the car give a nut of a coupling bolt of fastening of an intermediate shaft of a steering column to a driving gear wheel of reechny transfer (see an illustration Fastening of an intermediate shaft of a steering column to a driving gear wheel of reechny transfer). At the corresponding complete set shift aside a fixing collar and disconnect a shaft from a gear wheel.

10. Turn out two bolts of fastening of a case of reechny transfer to a stretcher. Remove the remote plugs/washers established between a stretcher and support of the steering mechanism (try to remember their landing situation) (see an illustration — the mechanism support with a manual drive is shown).

11. Carefully take assembly of the steering mechanism from under the right board of the car.

Major maintenance

PERFORMANCE ORDER

1. Attentively examine assembly of the steering mechanism on existence of signs of wear and mechanical damages. Check freedom of moving to a lath in all range of its course: the lath should move without breakthroughs and excessive люфта). Major maintenance of reechny transfer demands from the performer of high qualification and his performance should be entrusted to specialists of car-care center. The unique components which replacement can be made by strengths of the amateur mechanic, tips of steering drafts (are see. Removal and installation of tips of steering drafts).
2. On the models equipped with system of hydrostrengthening of a wheel, examine all shtutserny sockets of hydraulic tubes on existence of traces of leaks. Make sure of reliability of a tightening of cap shtutserny nuts. Also examine on existence of signs of development of leaks the executive cylinder of the steering amplifier. In case of need replace the failed components.

Installation

Installation is made upside-down. Pay attention to the next moments:
   a) Before installation of the steering mechanism on the car center the provision of a gear lath, having brought it into the situation answering to the rectilinear provision of operated wheels;
   b) Track correctness of installation of remote plugs/washers of support of fastening of the steering mechanism on a stretcher. Do not forget to put a washer under heads of fixing bolts;
   c) For fastening of spherical fingers of tips of steering drafts use new nuts. Replace also a nut of a coupling bolt of the kardanny hinge of a steering shaft;
   d) On the models equipped with system of hydrostrengthening of a wheel, replace sealing elements of shtutserny sockets of connection to a case of reechny transfer of hydraulic tubes;
   e) Track that the steering wheel and a lath of the steering mechanism occupied provisions. Answering to a rectilinear arrangement of operated wheels of the car, after it start fastening of an intermediate shaft to a driving gear wheel of reechny transfer;
   f) On the models equipped with system of hydrostrengthening of a wheel, after car lowering on the earth do not forget to tighten spuskny the gate of a regulator of pressure and will move a control lever a suspension bracket in the situation "Maximum";
   g) In summary check adjustment of corners of installation of forward wheels (see. Corners of installation of wheels - the general information, check and adjustment of convergence of forward wheels).
