Transmission note:
1, so that the North Ben V3 engine parts in the economic speed range, as far as possible with high speed gear, make full use of engine power.
2, in the acceleration, the use of more than one stall control, make full use of the economic speed range.
3, downhill should make full use of engine braking effect.
4, consider the traffic situation in advance, when not necessary, do not use braking or acceleration, to make full use of the vehicle inertia.
Shift of ZF synchronous transmission
1, as long as the operation of the transmission method is correct (that is, do not loosen the throttle), then, if the driver to choose an inappropriate gear, the shift is arduous, and the transmission will be issued a harsh noise. In this way, it is necessary to remind the driver to realize that the selected gear is not appropriate.
2, if the loose throttle shift, synchronous pressure will be reduced, there is no indication that the selected gear is appropriate.
3, the shift frequency under the condition of no loose throttle operation have significant effect on the fuel types of transmission synchronizer.
4, North Ben V3 parts synchronizer gear shift action should be smooth and not hasty, the correct shift steps are as follows:
Step on the clutch pedal (for this purpose, the driver’s seat must be properly adjusted) to drive the shift lever to the desired position smoothly and accurately. In a certain position, will encounter a certain degree of resistance, the synchronization mechanism began to work. Gradually force on the shift lever, don’t push, then release the clutch plate. In this position not to seize lashing gear lever. A fraction of a second (sync time), the gear is easy to change.
The shifting process is always: “tuidang – synchronous – joint”.
Increase of resistance must be overcome when shifting with the transmission size increases, in the low bit synchronous resistance will also increase, such as shift on the ramp, synchronization resistance is very large, the shift force applied to some.
The shift, in order to protect the North-Benz V3 parts of clutch, engine and transmission device itself does not overload and damage, to ensure that no wrong file, that is to say, only when the vehicle speed is not higher than the maximum speed to choose low can achieve, can downshift.
The reverse change only when parking, otherwise, may damage the shift sleeve.
Clutch use
Shift, the clutch pedal should be taken to the bottom, if not in the end or the clutch adjustment is not good (not completely separated, the shift will be a problem, and the synchronizer and the sleeve will suffer greater wear.
The required clearance of the pedal and clutch should be checked regularly.
5, emergency handling
Synchronizer type transmission for 8, GP and GPA. If the compressed air system failure, unable to carry out regional shift, you can manually shift to the low-grade area. To this end, first release shift pull arm and shift cylinder continuously, then hand arm pull to the direction of the engine, and then change into low-grade area, with less than 4 stalls stalls starting the vehicle to the nearest repair shop.
6, drag
The following protective measures should be taken when the vehicle is damaged:
7, for the 8 files, GP and GPA transmission, towed distance within 100 km, the gear lever must change to high-grade area (5~8) neutral file, and check whether the transmission is in the upscale district – viewing lamp on the instrument panel, side arm pull gearshift position. Towing speed should not exceed 60 km / h.
Attention! If the auxiliary gearbox can’t hang in the upscale district, or being towed from more than 100 kilometers, must make the transmission shaft and the front axle disengaged. At this point, the speed can not be limited.
8, for the 5 speed transmission, being towed at a distance of 100 km or less, the shift lever must change to the 2~3 file to the neutral position, and observe the dashboard lights, check in the neutral position, towing speed not exceeding 60 km / h. Note: if the transmission input end or the output end cap must be stuck not rotating drive shaft and the rear axle can be disengaged, then the speed limit.
9, for the 6 speed transmission, being towed at a distance of 100 km or less, the shift lever must be in neutral position (3~4) file, and observe the dashboard lights, check in the neutral position, towing speed not exceeding 60 km / h. Note: if the transmission input end or the output end stuck cannot rotate to keep the drive shaft and the rear axle can be disengaged, then the speed limit.
In addition, pay attention to the instructions in the car manual.
