Removal карданной transfers from the car
Before removal карданной transfers it is necessary to make labels of mutual angular position of a sliding plug and a transmission shaft. It is convenient to do labels by a paint on a reflector of a sliding plug and the transmission extension piece. Then to clear of a dirt an acting carving part of bolts of fastening to a flange of the back bridge and to turn away them. To turn away a nut of fastening of an intermediate support and to release it from a frame cross-beam. After that it is necessary to shift карданную transfer forward, to disconnect it from a bridge flange. For simplification of this operation if necessary it is possible to strike a hammer through a copper lining on a flange of the back hinge in a place designated by the letter And (fig. 5.28 see). Then карданной transfers take out the forward sliding end from the extension piece of a box and tag a paint at an end face of a conducted shaft of a transmission. Having removed карданную transfer, it is necessary to protect at once a shaft of a sliding plug from pollution (for example to tie with a pure fabric), and an aperture in a box to close a pure stopper.
Before to assort карданную transfer, it is necessary for clearing carefully, and dismantling places to wash out kerosene.
For dismantle of an intermediate support it is necessary to make labels a paint on a pipe of an intermediate shaft and on шлицевой to a plug of the average hinge that at assemblage шлицы a shaft of an intermediate shaft and a plug have occupied former position. To remove with шлицев an intermediate shaft a plug blows of a copper hammer or through a copper lining in a place designated by letter Г (fig. 5.28 see)
If the plug does not act in film, it is necessary to disassemble the average hinge and a plug, the hinge and a plug to remove a stripper. The intermediate support can be removed from a shaft, striking on a shaft shaft through a wooden or copper lining.
Before dismantling of hinges to mark with a paint mutual position of plugs. To remove lock rings 3 (fig. 5.28 see) from bearings крестовины, having established a screw-driver in an end face of a ring and slightly striking on its handle. If the ring is turned in a flute, to substitute the second screw-driver under other end face of a ring.
After removal of rings выпрессовать bearings in a vice, as is shown in fig. 5.30, having a press butterdish from outside оправки.
Check of a technical condition of details
It is necessary to wash out hinge details, to clean channels крестовины. They should be pure and are visible through. If on thorns крестовины there are flutes — prints of needles depth more than 0,1 mm the detail should replace. To check up the ball valve of a press butterdish. To exclude hit of a dirt in the bearing.
To be convinced of dense landing иглодержателей in glasses of bearings, in a good condition of a working edge of a cuff, in integrity and correct landing of their springs.
In case of use new крестовины in gathering it is necessary for clearing from dense консервационной greasings, including channels. To check up presence of springs of cuffs.
It is impossible to mix needles of different bearings. As a last resort it is possible to use the complete set of needles from other bearing.
At survey of an intermediate support pay attention to a bearing condition.
Assemblage карданных hinges demands special carefulness and cleanliness on a workplace.
If assemblage is made with use new крестовины in gathering with new bearings it is necessary to put on first of all thorns крестовины cuffs against the stop in a basic ring.
At use of the bearings which were in the use, cuffs should remain in иглодержателях bearings.
Assemblage to carry out in a following order:
- To fill in oil in glasses of bearings to the middle of needles;
- To insert pair of thorns крестовины into apertures of ears of one of plugs. Thus the relative positioning of plugs should be kept on labels as was before dismantling;
- To insert bearings into plug apertures, partially having put on them thorns, and, rotating крестовину every which way (fig. 5.31), smoothly to shift bearings against the stop (fig. 5.31);
- Easy blow of a hammer to establish a lock ring 2 in a bearing flute. Thus it is necessary to hold a ring, as it is possible it вылетание from a flute;
- To put a ring-opravku 1 on an external end face of an ear of a plug with the stopped bearing (fig. 5.31) and допрессовать крестовину with bearings against the stop a lock ring in the bearing and a plug then to insert the second lock ring;
- To collect second half of hinge in the same sequence.
The collected hinge should not have jammings and variable effort проворачивания. The moment проворачивания should not exceed hinges 2 Н·м (0,2 кгс·м). If hard, it is necessary to strike hinges some times a hammer in the places designated by the letter And (fig. 5.28 see);
The intermediate support gathers in a following order:
- запрессовать the bearing in a holder against the stop, making effort an external ring of the bearing;
- Holder with the bearing to establish in an internal cavity of a pillow of an intermediate support;
- Intermediate support with the bearing to establish on шлицевой the end against the stop in a fillet, making effort an end face of a holder of the bearing;
- To enclose in a flute шлицевой plugs a sealing ring;
- To establish шлицевую a plug 11 on шлицы a shaft on earlier put labels;
- Bolt 16 with put on it a lock plate 15 and a washer 17 to screw on 2—3 threads of a carving in an end face шлицевого the end of an intermediate shaft; to establish a washer 17 in a cut шлицевой plugs 11 so that an oval aperture of a washer 17 there were in parallel axes of apertures of ears of a plug;
- Having placed fixing short moustache of a lock plate 15 in an oval aperture of a washer 17, to press a plate to a washer and to tighten a bolt 16, having tightened its moment 40—45 H·м (4,0—4,5 кгс·м).
- To stop a bolt 16, having unbent on the verge of its head petals of a lock plate 15;
- To check up ease of rotation of the bearing of an intermediate support, having eliminated if necessary the reason задевания details;
- To stop a bolt 16, having unbent on a side of its head petals of a lock plate 15.
After assemblage карданной transfers it is necessary to make its dynamic balancing.
Installation карданной transfers on the car
It is originally necessary to insert a sliding plug of the forward hinge into the transmission extension piece. A flange of the back hinge to connect to a flange of a leading gear wheel of the back bridge and to tighten carving fastening by the moment 27—30 Н·м (2,7—3,0 кгс·м). An intermediate support to establish on a cross-beam of a frame and, having convinced of absence of its warp concerning a longitudinal axis of the car, to tighten nuts the moment of force 12—18 Н·м (1,2—1,8 кгс·м).
Fastening of an intermediate support to a cross-beam to make only on the car standing on wheels.
