The main point of discussion here is the case of the maintenance of this vehicle by the public, which is equipped with a seven-speed dry double-disconnected gearbox, which may have recently experienced, for weather reasons, a failure to start refuelling in cold cars, which is frequent, with six to seven cases in 10 cold cars. So i came here to see what caused it。
The maintenance technician checked the failure code for the fast-moving gearbox and found a code on the failure of the clutch, but in combination with the failure of the fast-moving, it was clear that there was a problem with the electrical unit. It explains the fact that the seven-speed dry double-disconnected gearbox, which was installed at speed, was found to be more than 172,000 kilometres in miles, and that, after 150,000 kilometres, the gearbox would fail more or less. The task of the maintenance was therefore to remove the gearbox and conduct a full inspection of the internal parts. A maintenance programme is also developed based on the degree of damage to the spare parts and the duration of the maintenance works is one day。
The two maintenance masters are slowing down the gearbox
The two maintenance masters are slowly lifting the fast-moving gearbox, and while lifting the gearbox, they are also required to keep an eye on the fittings around the gearbox, whether or not there are obstacles, and if any, to dispose of them in a timely manner in order to prevent them from falling。

This gearbox is the most widely used vehicle in the current market, the popular series 1. 4t, which is equipped with two types of oil, one for gear and the other for mechanical units. The gearbox design is similar to that of the manual gearbox, which only removes the clutch and adds additional control units on a manual block. So the rotor oil inside the gearbox is the same time as the hand-to-hand fuel changer in the gearbox, just 100,000 kilometres. The oil repair and repair technicians of the mechanical and electrical units recommended that the vehicles be replaced earlier and that the replacement be most appropriate when the vehicles were driven for three years or 60,000 kilometres。
That's what happens when there's trouble, and the guys can keep it in case. It is also recommended that when a car crash occurs, it should be checked and judged in a timely manner, so that not only will the failure not be aggravated, but it will also save many unnecessary maintenance costs
The maintenance technician used tools to extract the clutch and was prepared to check for damage to the clutch。
The damage was checked and it was found that the gap between the two sets of clutches was clearly too large and badly worn, which was not properly used and could only be resolved by replacing the whole new clutch。

The maintenance technician is preparing to dismantle the electrical units of the machines and to check for internal damage to the units。
This is what happens when the electrical units are removed and there is a severe wear in the interior of the fittings, the electromagnetic valves and the valves, which is highly relevant for the long-term failure to replace the unit oils, as the lack of oil for the oils increases the amount of impurities in the interior, resulting in the cut-off of the electromagnetic valves and valves and the consequent wear and tear. From this, the importance of transformer tank oil can be seen。
The inspection revealed that there were clearly too large gaps in the fast-moving gearbox and severe wear on the surface, damage to the electromagnetic valves inside the unit, removal of gears, and wear and tear on the fork. Maintenance of the electrical units and replacement of badly damaged spare parts resulted in the breakdown of the speed transformer and the recovery of normal vehicle。
The cvtc reminds the carmates that when a car crash occurs, it is important not to lose sight of it, to check it first, and not to wait until the problem gets worse, which not only makes it more problematic, but also more expensive to maintain. Regular driving does not involve violent driving, frequent shifts and regular changes to transformer tank oil, thus extending the life of the transformer.
