10.5. Additional protection of spherical hinges of steering drafts


Spherical hinges are only capable to serve long in case water and dirt do not get to them. Consolidation of hinges can be improved and by that to increase their durability if over the available factory rubber sealant 2 to put on the washer 3 which is cut out from soft foam rubber 10-15 mm thick each spherical finger (previously having taken out it from a nest).

Simpler, but the effective way of protection of spherical hinges consists that they are wrapped up in 2–3 layers a polyvinylchloride film. The ends of a film fix by an insulating tape.

Durability spherical a sharnirova of a steering trapeze and a suspension bracket in many respects depends on an integrity of rubber protective covers. The damaged covers can be replaced with scraps of the bicycle camera 100-120 mm long successfully. Fix an internal part of a cover by rings 10 mm wide from the same camera, and external on draft – a copper wire with a diameter about 1 mm.

That hinges of a steering trapeze of cars served longer, cut out a ring with an outer diameter of 65 mm from foam rubber 40 mm thick and internal – 10 mm. Impregnate its nigroly and, having slightly wrung out, put in a cover of the hinge greased "with Litol 24" at assembly. Observations show what нигрол protects the hinge from water better, than "Litol 24" which should fill a cover. At the same time also scarce lubricant is saved.

The sticker of a rubber patch is usually useless as in operating time of a cover it falls off. It is possible to restore tightness of several covers in such a way. To grease the pure internal and external surfaces of a cover fat-free by gasoline with 88 glue and to impose a layer of fine kapron fabric (a piece of a women's stocking). Then – two more layers, too with glue.

After drying to put covers on the car where they will regularly serve.

How to preserve hinges of steering drafts? On cars at which they are greased through press butterdishes by means of the syringe, recommend to draw in before this operation a hinge spring a clamp. Several excess minutes on service of the car – but a guarantee that lubricant in the hinge is completely replaced, are removed abrasive particles, dirt.

On some models hinges of steering drafts have no press butterdishes for lubricant. Therefore it is necessary from time to time (through 3–5 thousand km of a run, depending on service conditions) to give to these knots "injection". Take the ordinary medical syringe on 10 cm3 and a thick needle to it. Warm нигрол or gipoidny lubricant, fill in the syringe and, having punctured a rubber antisplash cap in the top part of the hinge, enter a portion of lubricant. the opening in rubber will drag on at once when you pull out a needle.

Hinges in the steering drive of some cars are not subject to greasing. Factory experts consider that in operation it is cheaper to replace worn-out knot new. From the point of view of the motorist it not absolutely so. To grease knot one-two times a year are cheaper, than to pay for a new detail and work on replacement. Therefore by car, without removing details, drill an opening with a diameter of 5,2 mm in the center of each cap. Accurately, that shaving did not get in hinges, cut in openings M6 carving, same, as well as in cases of spherical hinges on suspension bracket levers. Make traffic jams 4-5 mm long for openings of M6 screws.

After such alteration every time, serving the car, fill up lubricant in all hinges, having adapted for this purpose a shtauferny butterdish 4 with the soldered carving tip of suitable diameter.

Maintenance instructions of many cars recommend to sort and resupply through each 100 thousand kilometers of a run lubricant in them. However in practice, and especially when driving on dirty roads, need for replenishment or replacement of lubricant arises much more often. Not to disassemble at the same time hinges, it is possible to make openings in which cut M6 carving in their carving traffic jams and to wrap in them butterdishes.

After such completion to grease hinges – business of several minutes, average hinges require the syringe with a curved tip. That dirt did not get to butterdishes, upon termination of work put on them rubber caps.
