Folksvagen Sharan/Sharan repair>> Coupling>> Malfunctions of coupling
Possible malfunctions of coupling, their reason and elimination methods are presented in the table.
If coupling completely is not switched off, it is possible with some effort, switching transfers on raised and lowered to reach to the nearest HUNDRED.
If coupling has refused by the included transfer for its deenergizing it is necessary to dump "gas" and to put the gear change lever in neutral position. If transfer has sunk down, it is possible to give small "gas" that the gear change lever was liberated.
To go with faulty coupling execute the following:
- Switch off the engine and include the first transfer;
- Include a starter and start the engine. The car will get under way from a place jerky until frequency of rotation of the engine will not be made even to transfer. If the engine cold it should be warmed up before it that it has not decayed at once. On equal road it is possible to reach on the second transfer to the nearest HUNDRED;
- If wish to try to be switched from the lowest transfer to the higher get under way as it has been described, on the first transfer, and then increase engine turns approximately to 1000 mines-1. Release a pedal of "gas" a little and include neutral transfer. Then completely release a pedal of "gas" and include the second transfer. At alignment of frequency of rotation of a cranked shaft of the engine and a transmission shaft the second transfer will join. If time for transfer switching was much add "gas", simultaneously having included transfer. Switching from the lowest transfer on the higher should be made only on low speeds, being switched, thus, for example, to the second transfer approximately on 20 km/h, on the third transfer approximately on 25 km/h and on the fourth transfer approximately on 35 km/h. To include the fifth transfer most likely it is not required;
- At switching frequency of rotation of a cranked shaft of the engine should be increased by the lowest transfer that it was possible to include the following transfer. Release a pedal of "gas" a little and include neutral transfer, and then again подгазуйте, simultaneously having moved the gear change lever to hill-climbing gear position.
Transfer should join without any problems. At switching on the lowest transfer also it is necessary to reduce speed to supervise a gear change. Whether at a gnash in a transmission it is necessary to check up again transfer is included. Thanks to transfer synchronizers should join without superfluous problems, the truth to do it it is necessary with some effort.
