7.4.7.5. Check of a technical condition of details of a reducer

Before survey of a detail of a reducer carefully wash out. It will facilitate revealing of deterioration and damage of details.

PERFORMANCE ORDER
1. Check up, whether is not present on teeths of gear wheels of the main transfer of damages and whether contact stains on working surfaces of teeths are correctly located. At inadmissible deterioration of a detail replace new; if gearing wrong, find the reason.
The prevention

In spare parts leading and conducted gear wheels are delivered by the complete set which has been picked up for noise and contact, therefore at damage of one gear wheel both replace.


2. Check up a condition of apertures of satellites and surfaces of their axis; at insignificant damages of a surface grind a fine-grained skin, and at serious damages of a detail replace new.
3. Check up surfaces of necks of gear wheels of semiaxes and their landing apertures in a differential box, eliminate damages, as well as to the previous operation.
4. Examine surfaces of basic washers of gear wheels of semiaxes, even insignificant damages eliminate. At replacement of the washers, new select for a thickness.
5. Examine roller bearings of a leading gear wheel and a differential box; they should be without deterioration, with smooth working surfaces. Replace bearings at the slightest doubt in their working capacity, the bad condition of bearings can cause noise and jamming of teeths.
6. Check up, whether is not present on картере and on a box of differential of deformations or cracks, if necessary, replace their new.
7. Carefully examine an epiploon of a leading gear wheel. At detection even insignificant damages or at deterioration of a working edge on width to 1 mm and more replace an epiploon new.
