The gears on the drive and output shafts are supported by «needles» (pin rollers). Thus, there is no rigid connection between shafts and gears. Gears, as already mentioned, always remain coupled.
When shifting gears, a connection is created between the gear and the shaft, not between the gears. To synchronize the speed of the shaft and gear, one part of the shaft slides relative to one part of the other shaft by means of friction elements.
Due to friction, the faster rotating shaft is decelerated until the synchronous rotation can create a connection that ensures the transmission of power flow. Since fractions of a second are required to synchronize the speed, do not forcefully «tear» shift lever, especially when the engine is cold and the gearbox oil is still thick.
Gear Shift Problems
If gears are shifted with difficulty, or after a long stop, the shift appears hard, then most often the source of the malfunction is in the clutch, and not in the gearbox (see section Help with faults in the Clutch chapter). The gearshift adjustment described below serves to bring the gearshift lever to the correct position and thereby straighten the shift strokes.
Adjustment of the mechanism of a gear change
On this model of the car, the gearshift mechanism is clearly visible in the section:
- 1 and 3 - fixing nuts of the body of the ball gear shift mechanism (2);
- 4 - rigid actuation rod;
- 5 - gearshift rod.
Order of execution
1. Unscrew the shift knob.
2. Remove the cuffs of the gearshift lever, to do this, remove the lower frame of the cuff from the clips.
3. Put the shift lever in neutral position.
4. Longitudinal installation: check the distance «A» = 37 mm, if necessary, adjust it as follows:
5. Slightly loosen the bolt «2» (picture below) and slide the shift lever board so that the distance is correct.
6. Tighten «2» with a tightening torque of 25 Nm.
7. Lateral adjustment: Loosen the nuts «3» And «4».
8. Tighten the nut «3» 25 Nm, nut «4» – by 10 Nm.
9. Loosen the bolt «1».
10. Place the shift lever vertically with a slight tilt back and install so that both lugs of the ball stop are at the same distance from the ball housing.
11. Tighten the bolt «1» at 25 Nm.
12. Finally, check the function: the gear lever in the neutral position must be in the plane of the 3/4th gear.
13. Check all gears by shifting. At the same time, pay attention to the functioning of the reverse gear lock.
14. Accurate installation: if the installation still does not give satisfactory results, loosen the nuts «3» And «4» body of the ball gear shift mechanism.
15. Move the lever to the right until it stops (transmission) and at the same time push the ball housing to the left towards the gear lever.
16. While holding the named parts in this position, tighten the nuts again «3» And «4».
Longitudinal shift lever adjustment: size «A» equal to 37 mm.
Adjusting the gearshift mechanism: in this figure, the bolts and nuts mentioned in the text are indicated by numbers.
Adjustment of the shift lever in the transverse position: both lugs of the ball stop must be at the same distance «A» from the ball body.
To gain access to the set screw of the gear lever, you need to lift the boot (2). To do this, remove from the mounting grooves (arrows) lower cuff frame. Then remove the soundproofing (1). Further visible:
- 3 - ball stop;
- 4 - ball body.
