Replacement of bearings of forward naves

2-рядные roller stupichny bearings have a tight design. Adjustment of a pretightness and stuffing of bearings by greasing is made at manufacturer. Bearings are calculated on all service life of the car and additional service do not need. Try not to allow pullings of nuts of fastening of power shafts above admissible value.

For performance of procedure the suitable press, or the workbench equipped with a big vice is required. Prepare also suitable opravka (face heads of the corresponding size will approach). Internal holders of bearings are put in a nave внатяг and sometimes act in film together with a nave. In such cases for their extraction it is necessary to use a special stripper of lezviyny type.

PERFORMANCE ORDER

1. Remove stupichny assembly (see. Removal and installation of stupichny assembly of a forward suspension bracket).
2. Strongly lay stupichny assembly on pair of wooden blocks, or clamp it in a vice with soft sponges. Rest an opravka suitable on the size against an internal end face of a flange of stupichny assembly, pull together a flange from the bearing. If the external part of an internal holder of the bearing remains in a nave, use for its extraction by a stripper (see the prevention at the beginning of the section).

3. Remove a lock ring of the bearing from an external end face of stupichny assembly.

4. In case of need plant an internal holder of the bearing back on a separator and strongly prop up inside of stupichny assembly. By means of an opravka suitable on the size выпрессуйте the bearing from a nave (the opravka should rest only against an end face of an internal holder of the bearing).

The lock ring of the bearing is subject to replacement without fail, regardless of its condition.

6. Slightly oil an external holder of the bearing and an axis of a flange of a nave.
7. Reliably prop up stupichny assembly and plant in it the bearing. Track perpendicularity of landing of the bearing. Opravka should rest only against a face surface of an external holder.
8. Having planted the bearing, fix it a new lock ring, having tracked correctness of landing of the last in the flute in stupichny assembly.
9. Prop up the outer side of stupichny assembly and with plant an internal holder of the bearing on a pin of a flange of a nave. Press the bearing against the stop in bearing coat hanger by means of an opravka resting against an end face of an internal holder.
