11. The press fitting of cones of lateral bearings in a box of differential is made by means of ST 498485400 drift.
12. After a press fitting of cones collect holders of lateral bearings:
a) By means of a mandrel of ST 498447100 fill NEW epiploons in the right and left holders;
b) By means of a mandrel of ST 398477702 put in the right and left holders of a holder of bearings;
c) Installation of a box of differential in a case is made as it should be, the return to a removal order.
19 Adjust a side play of gearing of koronchaty and leading gear wheels and a pretightness of bearings.
a) By means of a key of ST 498427200 develop the leading gear wheel for shrinkage of lateral bearings;
b) By means of a key of ST 399780111 screw the left holder to his easy emphasis in a key;
c) Develop the left holder back approximately on 1.5 teeth, then tighten him on 2 teeth;
d) Temporarily establish a lock plate so that the holder could move on 0.5 teeth;
e) Measure a side play of gearing of gear wheels. In case of need anew adjust a side play and a pretightness of bearings.
13. Achieve combination of adjusting tags on a case of back differential and on holders then temporarily remove the holder. Grease and establish a sealing ring on the place, then screw and tighten bolts of fastening of lock plates with the demanded effort (25 Nanometers).
14. Further assembly of back differential is made as it should be, the return to an order of dismantle of components.
15. Check of back differential of VA type is made similar to check of differential of T-type. |
