Spherical hinges are capable to serve long only in case water and dirt do not get to them. Consolidation of hinges can be improved and by that to increase their durability if on each spherical finger (previously having taken out it from a nest) over an available factory rubber sealant 2 to put on the washer 3 which has been cut out from soft foam rubber in thickness of 10-15 mm.
Simpler, but the effective way of protection of spherical hinges consists that wrap up them in 2–3 layers a polyvinylchloride film. The ends of a film fix an insulating tape.
The durability spherical шарнирова a steering trapeze and a suspension bracket in many respects depends on an integrity of rubber protective covers. It is possible to replace the damaged covers successfully with scraps of the bicycle chamber in length of 100-120 mm. An internal part of a cover fix rings the in width of 10 mm from the same chamber, and external on draft – a copper wire in diameter about 1 mm.
That hinges of a steering trapeze of cars served more long, from foam rubber in thickness of 40 mm cut out a ring in external diameter of 65 mm and internal – 10 mm. Impregnate its nigroly and, having slightly wrung out, put in a cover of the hinge greased "Litol 24" at assembly. Supervision show that нигрол protects the hinge from water better, than "Litol 24" to which should fill a cover. Scarce greasing is thus saved also.
The sticker of a rubber patch is usually useless, as in cover operating time it falls off. It is possible to restore tightness of several covers in such a way. The pure fat-free gasoline internal and external surfaces of a cover to grease with glue "88" and to impose a layer of a fine kapron fabric (a piece of a female stocking). Then – two more layers, too with glue.
After drying to put covers on the car where they will regularly serve.
How to save up hinges of steering drafts? On cars at which they are greased through press butterdishes by means of a syringe, recommend to draw in before this operation a hinge spring a clamp. Some superfluous minutes on car service – but a guarantee that greasing in the hinge is completely replaced, abrasive particles, dirt are removed.
On some models hinges of steering drafts have no press butterdishes for greasing. Therefore it is necessary from time to time (through 3–5 thousand km of run, depending on service conditions) to give to these knots "injection". Take a usual medical syringe on 10 cm3 and a thick needle to it. Warm up нигрол or gipoidny greasing, fill in a syringe and, having punctured a rubber antisplash cap in the top part of the hinge, enter a portion of greasing. the opening in rubber will be tightened at once, when you pull out a needle.
Hinges in a steering drive of some cars are not subject to greasing. Factory experts consider that in operation to replace worn-out knot new cheaper. From the point of view of the motorist it not absolutely so. To grease knot of one-two time a year is cheaper, than to pay for a new detail and work on replacement. Therefore by the car, without removing details, drill in the center of each cap an opening in diameter of 5,2 mm. Accurately, that shaving did not get in hinges, cut in openings carving М6, same, as well as in cases of spherical hinges on suspension bracket levers. Of M6 screws make jams in length of 4-5 mm for openings.
After such alteration each time, serving the car, fill up greasing 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 assort and resupply through each 100 thousand kilometers of run of greasing in them. However in practice, and especially when driving on dirty roads, need for replenishment or replacement of greasing arises much more often. Not to assort thus hinges, it is possible to make in their carving jams of an opening in which cut carving М6, and to wrap in them butterdishes.
After such completion to grease hinges – business of several minutes, only average hinges need a syringe with the bent tip. That dirt did not get to butterdishes, upon termination of work put on them rubber caps.
