"Gazelle" Gas-2705>> Transmission>> The back bridge>> Maintenance service of the back bridge
Service of the back bridge consists in periodic check of level of oil in картере, доливке it and change according to a greasing card, clearing of a dirt сапуна, pulling up of a nut of a flange of a leading gear wheel, nuts of fastening of semiaxes, check and restoration of adjustments of bearings of naves of the wheels, a leading gear wheel and differential.

It is forbidden to make replacement of the oil filled on Open Society "GAS", before run of 60 000 km.

Fig. 5.32. The back bridge with a type beam банджо with a separate reducer (an average part): 1 — a nut; 2 — a flange of a leading gear wheel; 3 — a cuff; 4, 6, 11 — bearings; 5 — a ring; 7 — an adjusting ring; 8 — картер a reducer; 9 — a leading gear wheel; 10 — differential; 12 — полуось; 13 — a lining; 14 — a lock plate; 15 — картер; 16 — a nut of bearings of differential; 17 — a cover of the bearing of differential; 18 — a stopper маслозаливного apertures; 19 — a conducted gear wheel; 20 — сапун

It is necessary to measure backlashes in the main transfer on the car after a detachment карданного a shaft. Before check of backlashes it is necessary to check up an inhaling of a nut of 1 flange of a leading gear wheel (fig. 5.32 see) for what it is necessary расшплинтовать a nut and to hold on its moment of force 160—200 Н·м (16—20 кгс·м). Moving of a flange of a leading gear wheel in axial and yгловом directions to check up backlashes. The axial backlash in bearings of a leading gear wheel is checked, how is specified in subsection «Adjustment of a pretightness of bearings of a leading gear wheel»).

For measurement full angular люфта a flange of a leading gear wheel it is necessary to make a label on an edge грязеотражателя a flange, to turn a flange against the stop to the left and to make on картере to the risk, coinciding with риской on a reflector. To turn a flange against the stop to the right and to make the second to risk on картере. To measure distance between risks on картере. If it exceeds 12 mm, it specifies in excessive deterioration of teeths of leading and conducted gear wheels of the main transfer, gear wheels of differential or шлицев semiaxial gear wheels and semiaxes.
Merge oil from картера the back bridge after its preliminary warming up. Check of level of oil and it доливку make through a bulk aperture картера on the car standing on a horizontal platform. Check should be made after a while after a trip to give the chance to oil to cool down and flow down from walls картера. The lack of oil or its surplus are equally harmful.
If bridge noise is raised so that is considered inadmissible from the point of view of comfort or causes fear of breakage, it is considered as malfunction. "Howl" the bridge (high-pitch tone noise) influences comfortableness, and it can be avoided if to exclude long driving in narrow ranges of speeds on which it is audible. Before to assort the bridge, it is necessary to be convinced that noise proceeds from the bridge. The faulty conducted disk of coupling, the tyre (noise varies at a different road covering and grows with increase in speed), the engine can be noise sources.
