1. Before dismantling of a box of gear shifting carefully clear a surface of its case of dirt, lubricant and oil.
2. Turn out a drain stopper and merge gearbox oil from a box. Having finished, replace a sealing washer, screw a stopper into place and tighten it with the required effort (41 ÷ 47 Nanometers).
3. Transfer the box removed from the car to the assembly stand No. 499937100.
4. Remember that all components removed in the course of dismantling should be cleared carefully, then to check their state and to try to estimate wear degree for the purpose of decision-making concerning their further use. |

Replacement of bearings is made in the following cases: In the presence of mechanical or corrosion damages of any of holders, and also balls/rollers; In the presence of obvious signs of excessive wear of bearing assembly; At violation of smoothness and noiselessness of rotation of the bearing, - the bearing can be reused if noise at its rotation disappears after assembly greasing by gearbox oil. Signs of need of replacement of plugs of gear wheels are: Excessive wear or mechanical damages of an external or internal surface of the plug; Wear of the shaft surface contacting to the plug.

Check of the back bearing of a shaft of the leading gear wheel of the main transfer is made before dismantling of knot of a secondary shaft. And it is necessary to remember that owing to a pretightness this bearing will rotate a little more hardly, than other. |
Replacement of gear wheels is made if: There are chips, cavities or other mechanical damages of teeths; There are signs of excessive wear or mechanical damages of an internal or face surface of gear wheels. Signs of need of replacement of the blocking rings of the synchronizer are: Excessive wear or damage of an internal or face surface; Gap Size between an end face of a ring and a shlitsevy wreath of a gear wheel becomes less than extreme admissible value (excessive density of landing of a ring to a gear wheel cone), the nominal rate of a gap makes 1 mm, the minimum admissible - 0.5 mm; Excessive wear or damage of the surfaces interfaced to crackers of the synchronizer. Crackers (the sliding keys) of the synchronizer are replaced in case of identification of any mechanical damages.
Authors of the present manual recommend to replace epiploons and rubber sealing rings regardless of their state.
The worn-out or damaged components of the main transfer and differential (a gear wheel, roller bearings, persistent washers, axes, pins, cases, etc.) are also subject to replacement.
